We have always used Garrett turbocharger components in building custom turbos and some of our proprietary turbo combinations for years because of their metallurgical qualities and consistent machining tolerances.   Their ball bearing turbochargers have been a stock item for years as well, especially the GT30 and GT35 sizes.  Now we offer the full line of Honeywell-Garrett turbochargers for purchase.  These turbos are now very much improved and capable of delivering outstanding performance which is proven by race use across the United States and all over the world.  With modern billet compressor wheels and bearing improvements these turbos are still the industry standard as far as fitment and performance with many options for turbine housings for tuning.  Many of their turbochargers have been extensively redesigned to offer increased airflow delivery and reduced weight overall to be very competitive in race applications.  The housings have undergone some additional machining operations to improve the compressor wheel inlet area aerodynamic efficiency.  On the turbine housing options there are more durable materials used in the castings along with expanded options for passage area and geometric tuning.  In a few words, these turbos are now ‘better than ever’.   Honeywell-Garrett are very much now the new standard in racing turbochargers with more and more top competitors relying on their turbochargers to provide boost for record-setting passes down the track and around the road course circuits. 

     Here at Exclusive Turbosystems we are best known for our custom-manufactured performance turbochargers which out-perform the expectations of our clients all the time.   Pictured to the left is one of a pair of R32 Skyline GTR Garrett T-25 turbochargers being upgraded with a billet compressor wheel and 360 degree thrust components, the inlet and outlet castings which have been both ported internally and polished externally, and the exhaust manifold which is ported and will be ceramic-coated.  We feel that every turbocharger can benefit from being ported internally similar to our manifolds because they are dealing with such high velocity exhaust gas volumes.  All of our signature turbos are ported internally and feature compressor housing polishing on their exteriors.  They all look like the castings you see to the left.  We are quite proud of the ‘liquid-metal’ finish we give castings like these for our clients.  They LOVE this look!


      So you need the one of the biggest, baddest turbochargers that Honeywell-Garrett offers for your engine?  Then you have found it with the GTX5533R lineup of turbo ‘Supercores’.  These turbos can deliver 1400 WHP from the 84mm all the way up to a stout 2300 WHP from the 98mm GTX5533R.  Yes, these feature a forged billet aluminum compressor wheel, and yes it has been redesigned with an improved aerodynamic profile.  Garrett went back to the drawing board and after substantial development on the profile of the 11-blade wheel was able to gain both and increase in airflow capacity along with boost response.   A feature that is new is the inclusion of a billet aluminum compressor backplate which offers a substantial weight savings over the first generation GTX5533R.  Another benefit of this new backing plate is its improved heat-dissipation characteristics.  This affords a reduction in bearing operating temperatures within the bearing housing which improves longevity.  The inlet, is of course, a precision-machined ported shroud for efficiency anti-surge characteristics.  On the critical turbine end of this ‘Supercore’ sits the latest 112mm Inconel wheel for massive exhaust gas capacity for making the most available torque available for driving the billet compressor wheel on the opposite end of the shaft.  The ceramic ball bearings are caged inside of a unique housing engineered with cast fins to provide extra surface area for cooling.  


     The compressor housing of the GTX5533R has a few features designed to extend performance to the ultimate level.  Honeywell-Garrett went back to the drawing board and redesign the housing for expanded airflow capacity with the Gen-2 billet compressor wheels and the casting is an even higher quality with smoother surfaces inside the scroll passages.  The anti-surge inlet has been machined with a distinct, rounded edge for a better surge resistance properties compared to the previous casting.  The 6” precision-machined inlet is matched by a 3.5” V-band outlet which allows for a secure connection to charge piping.  The .96 A/R has large volume passages cast in for superior flow dynamics with the 133mm (exducer diameter) GTX55R compressor wheels which are fitted inside and matched specifically to each casting.  Additionally, a speed sensor port is pre-machined into these housings so that compressor wheel acceleration can be accurately monitored during a race.  


     The turbine housings available for fitment to these ‘Supercores’ are specifically matched to the 112mm turbine owheels flow rate characteristics so that both gas volume and velocity is at optimized levels for driving the billet compressor wheels attached to the opposite end of the shaft.  The scroll inlets are cast from high Nickel-content Stainless material with smooth inner surfaces befitting a race turbocharger.  On the outlet a V-band flange is integral with the casting for a low-restriction gas passage into the downpipe.  Several SFI-certified housings are available to make you legal at the track if needed.  Each one features a dowel drilled into the turbine outlet to prevent a turbine wheel from exiting the turbocharger in the unlikely event of a failure.


     These turbos are the best available from Garrett Honeywell.  With their advanced compressor wheel designs, specialized machining of the compressor housings, proven ball-bearing shaft support structures, and numerous turbine housing options available for tuning, the GTX5533R turbos are popular choices for competition engines across the country.  A pair of these turbos can easily deliver the pressurized air to support well over 4000 HP on a well-built Mountain motor in a Pro-Mod, or can be used to deliver the boost on a single turbo engine of modest displacement just as effectively.  GTX5533R turbos are designed to be durable and very efficient in delivering massive amounts of pressurized air, while being responsive and simple to fit onto a modern race engine.  They are THE standard by which competition turbochargers are measured by.


     Honeywell-Garrett offers the GTX5533R as a ‘supercore’ minus the turbine housing and clamps.  This allows you to purchase any of the turbine housing options available to outfit your turbocharger perfectly to the engine, and fine-tune the response/boost delivery curve.  With 8 distinct housing choices available that each fit the entire selection of GTX5533R supercores, you have plenty of options.

Large-Frame Honeywell-Garrett Competition Ball Bearing Turbochargers

Honeywell-Garrett GTX5533R Dual Ball Bearing 85mm - 98mm Race Turbocharger


     The GTX55R turbo, just what is needed for making in between 1400 HP and 2500 with a single turbocharger.  These are commonly fitted to some of the top Pro-Mod engines across the country for a reason, they deliver the goods when it counts.

     Honeywell-Garrett GTX5018R Dual Ball Bearing 82mm - 88mm Race Turbocharger.


     By combining a Gen 2 compressor housing with a original GTX billet compressor wheel Garrett has created a high-performance turbocharger without the price tag of the latest Gen 2 fully updated turbochargers.  These turbos are quite potent to be sure, and can deliver airflow enough to support 950 HP up to 1600 HP per turbocharger.

     The GTX5018R was designed by Honeywell-Garrett to be an excellent high-value option among the 82mm-88mm competition turbochargers.  This large frame dual ceramic bearing turbocharger features a combination of either a 82mm, 84mm, 86mm, or 88mm inducer compressor wheel that has an outer diameter of  118mm, combined with a turbine shaft that has a 99mm outer diameter wheel.  With a flow rating of about 165 lbs/hr (for the 88mm) and a peak efficiency of an impressively high 79%, this turbo can boast a airflow delivery capacity of over 1600 HP.  Excellent for Pro-Mod engines built to deliver 3200 HP with a twin-turbo system feeding the intake plenum.


     At the heart of each GTX5018 is a second generation 11-blade billet, forged aluminum alloy  compressor wheel that has been redesigned with an advanced aerodynamic profile for the blades.  It’s shaft mass has been reduced to the extent that the nut to secure the wheel onto the shaft is integrated into the billet aluminum compressor wheel form.  Another element of this wheel‘s design is its large outer diameter which is key to maximizing the airflow volume that this turbo has the capability of moving.  At the blade tips the base of the blade form is machined away to reduce inertia while allowing essentially the same airflow volume capacity.  This effectively speeds up compressor response and improves efficiency of the wheel within the housing.  A billet aluminum backing plate which has been precisely machined is bolted to the bearing housing.  Not only is it dramatically lighter than the older cast iron backing plate but improves heat dissipation from bearing housing as well.  The turbine shaft is supported by 2 ceramic ball bearings which allow both low-friction rotor-group acceleration and high thrust load capacity.  The bearing housing itself is cast with large heat-dissipation fins to reduce inner temperatures and promote better lubrication effectiveness.  At the working side of the CHRA is the 118mm Inconel alloy turbine wheel with its 91mm exducer and advanced blade profiles.  This wheel is large enough to to have an effective rotational torque to spin the 118mm compressor wheel without being too heavy for rotor-group responsiveness with the available exhaust gas energy.


     Surrounding the turbine wheel and cast specifically for its flow characteristics is a choice of 2 cast 85-trim housings with V-band discharge outlets.  These single scroll housings can be had in either a .96 A/R or 1.39 A/R T6 flanged configuration.  Both housings have a low-turbulence V-band outlet to allow easy exhaust gas exit from the turbine wheel blades into the downpipe.  With these 2 choices you should find just the right combination to use for your compressor size with the GTX5018R turbocharger.


     On the cold side of the GTX5018R turbocharger we have a .69 A/R housing that has a 3.5” v-band outlet and 6” compressor inlet.  A cavity surrounds the compressor inlet inner casting and serves to reduce the effects of potentially damaging surge.  The scroll passage of the compressor housing is consistently smooth inside to promote airflow efficiency from the compressor wheel.  With its .69 A/R dimensions, this housing affords strong boost response from these 82mm - 88mm sized compressor wheels.  The combined improvements in compressor wheel dynamics and the strong boost-building response of this housing are key ingredients in making the GTX5018R an excellent value for current turbocharged race engines.


     The GTX5018R is offered as a ‘supercore’ minus the turbine housing and its clamps.  The turbine housing can be purchased separately allowing a choice of turbocharger response levels and ultimate airflow capacity overall.

     Honeywell-Garrett GTX5008R Dual Ball Bearing 80mm Billet Compressor Class -Legal Race Turbocharger


     The GTX5008R turbocharger takes the 80mm compressor wheel to the very limit for a near 1300 HP airflow capability.  It’s compressor wheel offers a 80% peak (compressor map) efficiency level which surpasses most similar wheel designs. 

     With a 80mm billet compressor wheel at the heart of the redesigned compressor housing the GTX5008R ball bearing turbocharger is a serious turbocharger designed to be a quick-response big HP turbocharger for race engines requiring a 1300 HP capable delivery.  Garrett specially designed the compressor wheel with a 108mm exterior diameter to take full advantage of the 80mm inducer class rules.  It has a unique wheel shape to enhance the blade area within the class rules dimensional limitations and offer a competitive edge among 80mm class-restricted turbochargers.  This Gen 1 compressor wheel was so well-designed that Garrett feels no need to drastically alter its profile for this latest GTX5008R ball-bearing turbo.  They didn’t want to ruin a good thing it seems.


     The compressor housing itself incorporates a fully machined inducer inlet area, a precision-machined v-band compressor discharge flange, and a port for a compressor wheel speed sensor.  Now you can attach a speed sensor to the turbocharger and data-log the shaft speed characteristics during a run.  Also, the backplate is a fully machined billet aluminum CNC-machined lightweight upgrade to the older cast iron backplate.  This billet backing plate reduces the turbocharger’s overall weight.  A ported shroud inlet allows a more efficient airflow signature through the compressor wheel blades and reduces wheel damaging surge effects.  The .69 A/R dimensions of this housing help to get stronger boost response from the 108mm (outer diameter) compressor wheel.  Garrett has gone through a lot of effort to make sure this GTX5008R turbocharger has a very efficient compressor section surrounding its billet wheel.


     The bearing housing has cast-in cooling fins and contains a dual ceramic ball-bearing cartridge to support the turbine shaft.  This dual bearing arrangement is key in keeping the rotor group components spinning in an ultra-low friction environment even during high thrust load conditions. The front (compressor-end) ceramic ball bearing handles the boost-induced thrust loads so that a separate thrust plate and washers aren’t needed.  Inside the bearing housing spins the turbine shaft with its 99mm 84-trim Inconel wheel.  This turbine wheel offers a large enough outer diameter to drive the larger compressor wheels yet low enough in mass to offer strong response characteristics.


     A pair of turbine housings are offered to match this GTX5008R Supercore a .96 A/R, and a 1.23 A/R.  With the .96 A/R housing option you will get the best response out of the GTX5008R especially with smaller displacement engines.  The 1.23 A/R will offer up the highest flow rates through the 99mm turbine wheel for the ultimate in airflow through the compressor wheel.  Both of these are open volute single scroll castings made from high nickel-content modular iron.  The turbine outlet has a v-band flange machined onto the housing for a low-turbulence gasket-free connection to the down-pipe.

     With a 88mm billet compressor wheel fitted inside a redesigned second-generation .69 A/R compressor housing, this gives the GTX4718R a true 1600 HP potential.  This is compressor configuration is coupled to a 93mm turbine wheel that has 4 A/R options to allow excellent tuneability as far as turbo response and matching to engine displacement and exhaust flow characteristics.  


     With a precision-machined anti-surge compressor inlet and integrated speed sensor port machined into the casting, this housing is packed with race-level features.  It offers a .69 A/R to get the best pressure building characteristics from the 118mm diameter compressor wheel.  The outlet has a precision-machined v-band flange for a high-pressure capable connection to the charge piping.  With the machined port you can attach a sensor and data-log the turbocharger acceleration during a run.


     The CHRA is built around a large-frame finned bearing housing which houses a pair of ceramic ball-bearings to support the turbine shaft precisely.  On the compressor end of the housing is a newly featured billet aluminum backing plate which is  both precision-machined for the shaft seal and offers a weight savings over the last generation cast iron backing plate.  Another benefit is an improvement in heat distribution away from the bearings inside the casting during operation.  For this GTX4718R turbocharger Garrett has selected the ‘713’ Inconel alloy 93mm turbine wheel with an 84mm exducer for driving the 88mm compressor wheel on the other end of the shaft.  It has the appropriate wheel diameter offering ideal rotational torque for the GTX4718R 160 lb-per-hour capable 11-blade compressor wheel.  


     Four options exist for turbine housings, all with 5” v-band outlets machined onto the discharge.  These are all T6 flanged from .96 A/R, 1.08 A/R, 1.23 A/R, to a 1.39 A/R and feature a 82 trim turbine housing arrangement.  These four options allow for easy fitment onto a variety of engine displacements from a mere 2.5L up to 10L and account for some adjustability in turbocharger response characteristics.  Put another way, the GTX4718R can work on anything from a Nissan Skyline (with its modest 2.5L inline 6-cylinder RB25DET engine) to a 8.0L V-10 Dodge Viper.  Pretty broad range of engines for sure.

Honeywell-Garrett GTX4508R Dual Ball Bearing 80mm T4 Race Turbocharger 


     The GTX4508R is the largest T4 turbocharger offered by Garrett.  This billet compressor wheel equipped beast has a dual ball-bearing heart and offers up to a 1250 HP of airflow capacity.  The CHRA is built with a compact bearing housing affording easier fitme


     Here we have the largest T4 turbocharger offered by Honeywell-Garrett the 1200+ HP GTX4508R.  The GTX4508R is not exactly like the other large-frame turbos as it is built with a more compact bearing housing that, when combined with its smaller T4 turbine housing dimensions, affords easier fitment in an engine bay.  The forged aluminum alloy billet compressor wheel is a 108mm diameter 11-blade design which is key to the GTX4508R’s stellar performance.  It is a dual ball-bearing turbocharger with twin-scroll turbine housings, both features are paramount to fast boost response.


     The GTX4508R CHRA has a water-cooler bearing housing with very compact dimensions from the backplate to the turbine housing flange.  This makes this turbocharger much shorter in length compared to the T6 housing GTX large-frame turbochargers.  The ability to plumb coolant lines into the bearing housing makes the GTX4508R operate at much lower temperatures which directly translates into better durability and reduce carbon build-up in the turbine section.  This housing contains a pair of proven ceramic ball-bearings to support the turbine shaft and bear the thrust loads as well.  These ball-bearings also are key to the turbcharger operating at very tight tolerances , key to maintaining aerodynamic efficiency of the rotor group spinning within the housings.  The 55-trim 11-blade billet aluminum compressor wheel has an 80mm inlet diameter and is 108mm in overall width.  It’s 1st Gen GTX profile has been proven to be very efficient at both spinning up to boost production rpms and flowing at least 15% more air volume than a comparable cast wheel of similar dimensions.  The 85-trim 87mm turbine wheel is also sized to offer plenty of rotational torque to drive the compressor wheel without being too heavy to spin-up quickly with the available exhaust gas energy. 


     On the compressor side of the GTX4508R turbo is a .69 A/R housing which has been redesigned to offer better airflow capacity and flow velocity characteristics.  The latest casting methods yield smoother scroll passages Internally and a better finish externally.  Each housing features a precision-machined anti-surge profile allowing more turbulence-free airflow into the compressor wheel inducer.  There is also a machined v-band flange integral with the discharge outlet of the compressor housing for a leak-free connection capable of containing high-boost pressures.


     Turbine housings are all v-band outlet equipped and have twin-scroll inlets.  With A/R options from 1.01 to 1.44, there is a wide range of exhaust flow dynamic tuning to get the GTX4508R perfectly matched to your engine.  The twin-scroll housing inlet really is 

very efficient for directing exhaust gas streams onto the turbine wheel blades at high velocities directly affecting turbine whell acceleration.  The twin scroll passages get the velocity up, and the A/R area allows for sufficient gas volume capacity.  


     Thecombined features of both the compressor and turbine housings make the GTX4508R respond extremely well with the compressor surge line well away from the peak efficiency area of the map.  To its credit, the GTX4508R makes fast turbo response and delivering well over 1000WHP look easy to do.  With its water-cooled bearings and tough and capable billet compressor wheel, it is safe to say this turbocharger will deliver its rated output year, after year, after year.

Garrett GTX4202R Dual Ball Bearing 76mm Race Turbocharger


     The GTX4202R is the ‘KISS’ turbocharger of the ball bearing variety.  It features a simple combination of housings, with just 2 exhaust housing options so that setup of this 1100+HP turbo is very easy.  The tough Honeywell-Garrett GTX4202R makes 1000 WHP and fast response real simple.

     Making 1000 WHP is simple with this 76mm turbocharger.  Combining a water-cooled bearing housing, a ball-bearing supported turbine shaft, and compact T4 housings adds up to a fast-spooling turbo that can ruin hard day-in, day-out, in either single or twin turbocharger setups alike.  A pair of these GTX4202R turbos will support 2200+HP at full chat.


     Dual ceramic ball-bearings support the 82mm turbine wheel which sit inside of a housing with cooling passages that you can easily run engine coolant through.  A pair of large ports are drilled into the casting so that large amounts of coolant can pass through and carry heat away from the turbocharger Itself.  The proven ceramic bearing architecture means low friction and high boost pressure load capacity alike.  Having a pair of precision ball-bearings also keeps the shaft spinning straight and true within the housings for consistent aerodynamic performance on the compressor and turbine side of the turbocharger.  A Gen-1 GTX billet aluminum compressor wheel with a 76mm inlet diameter and a 102mm outer diameter, offering proven durability and solid performance which peaks at 78% aerodynamic efficiency.  This CHRA offers a solid foundtion for the GTX4202R turbocharger.


     The compressor housing is cast with a .60 A/R ratio relationship betweven the compressor wheel and housing discharge offering very strong boost pressure building characteristics.  Anti-surge slots are cast into the compressor inlet to keep the compressor wheel operating in peak efficiency over a wide boost range.  A v-band outlet has been machined into the compressor housing discharge for a tight, high-pressure connection to the charge piping.  


     A pair of twin scroll turbine housings surround the 84-trim turbine wheel.  These housings are well suited to provide excellent turbine wheel acceleration (1.01 A/R turbine housing) with a tuning range to allow more top-end flow if needed (1.15 A/R turbine housing).  The 82mm turbine wheel size affords an ideal relationship for spinning up the compressor wheel on the other end very fast indeed.  Both feature a casting that has provision for a machined v-band discharge outlet for low-turbulence exhaust flow into the downpipe.



     The combination of a durable water-cooled bearing housing, low-friction ball-bearing CHRA, responsive turbine housing arrangement, and proven billet compressor wheel aerodynamic performance, makes the GTX4202R an easy choice when space is somewhat limited and each turbocharger needs to support 1100 HP consistently.  These turbos are rated to support 525 HP up to 1120 HP depending on boost pressure settings, and perfect with modest displacement engines from 2.0 liters all the way up to 7.0 liters.  Put another way, they will spool-up just as well on a 4-cylinder Mitsubishi EVO as a stroked small block V8 muscle car.

     The GTX4294R represents a solid performer in the 700 to 1000 HP range of turbochargers.  Its ball bearing supported turbine shaft is coupled to a 70m billet compressor wheel which can coax almost 1000 HP out of you engine with extremely quick boost response.  This is more responsive than even other ball-bearing equiped turbochargers because of its low turbine wheel and compressor wheel inertia combination.  


     Honeywell-Garrett equips the GTX4294R with a water cooled bearing housing to encase its dual ceramic ball-bearings.  This affords a more durable environment and improved resistance to carbon-buildup in the turbine housing area.  Two

 Large ports are on opposite sides of the housing for a cross-flow cooling action of the coolant as it circulates through the housing cavity.  The 82mm turbine wheel supports a 70mm inlet diameter and 94mm outer diameter billet 11-blade compressor wheel.  The advanced profile of the compressor wheel has less mass at the blade roots with blade tip extensions to minimize inertia while expanding compressor wheel airflow capacity and acceleration capabilities.  This compresor wheel design offers nearly 20% better efficiency and airflow capacity over a comparable cast aluminum wheel design.  Added to the lower friction of the dual ball-bearing shaft support, this CHRA has very fast response to translating exhaust gas energy delivered by the turbine housing into turbine shaft rpms.  Even with its modest 70mm compressor wheel inlet size the overall efficiency of the CHRA can support just 5% shy of the 1000 HP level of airflow.


     Both the compressor and turbine housings have v-band flanges machined into the discharges of the outlets.  This affords a high-boost capable seal on the compressor discharge, and a smooth reduced turbulence gas flow into the downpipe from the turbine housing outlet.  The compressor housing itself features a .60 A/R which keeps the compressor wheel building boost pressure quickly.  Anti-surge porting of the compressor housing inlet extends compressor map efficiency and reduces the possibility of wheel damage from surge.  Each of the 2 turbine housing options has a twin-scroll inlet for the most effective gas velocity acceleration at the turbine wheel blades.  This ‘porting’ of the housing actually sets up two swirling columns of exhaust gas directed at the blades and increases the velocity of the gasses which can flow into the turbine wheel.  These attributes are exactly why twin-scroll housings offer better turbocharger responsiveness (with a negligible penalty in ultimate gas volume) compared to an open-volute housing.


     While the 1.01 A/R turbine housing will produce the best boost response curve with the GTX4294R, it must be said that even the 1.15 A/R turbine housing equipped turbo would have few piers if turbocharger acceleration were to be measured.  Consider the 1.01 A/R housing the best choice for setting up your engine for the best throttle response possible, essentially mimicking a naturally aspirated power delivery.  The 1.15 A/R housing simply extends the the airflow capacity further.  Engines of very modest displacement of 2.0 liters and even less will be able to get excellent response with this turbocharger, and larger engines like a 7.0 liter V8 will have essentially instantaneous throttle response and power delivery.  Utilizing a pair of GTX4294R turbos on an engine gives an output of 1900 HP without needing to have mountain-motor size engine displacement to get the turbos to spool-up well.

Take a good look at the 1000 HP capable Honeywell-Garrett GTX3584RS.  This compact powerhouse of a turbo features a dual ball-bearing core and Gen-2 billet compressor aerodynamics, with numerous turbine housing options for tuning exactly right level of turbo response to match your engine build.  Use a pair of GTX3584RS turbos to support a healthy 2000 HP with phenomenal response and proven toughness in the heat of competition.

     At the cold end of the GTX3584RS is a housing with several key improvements to complement the aerodynamic performance of the compressor wheel.  The inlet has a ported shroud surrounding the compressor inlet for anti-surge properties.  An extensive amount of precision-machining has been performed on the inlet area to keep the air flow within design parameters.  For monitoring compressor wheel acceleration, a port has been drilled into the housing exterior for a speed sensor.  Compressor discharge on this housing can be either a v-band connection or a beaded tubular exit.  The entire housing has been cast with an improved method which produces a smoother surface both inside and out.  It’s .72 A/R compressor-to-discharge ratio lends itself to getting the maximum airflow out of the compressor wheel and is larger than the GTX3582R compressor housing.  Like we said, many key improvements. 


     On the hot end of the GTX3584RS there are 3 distinct housing options for tuning the turbine wheel acceleration curve in a range from higher velocity to higher volume.  These special cast Stainless Steel, high-nickel-content housings feature v-band inlets which are precisely machined onto the housings.  The .83 A/R housing represents the best option for velocity and response while the 1.21 A/R housing will produce the best volume and top-end airflow capability of the turbocharger.  Each of these housings features a unique internal profile perfectly matched to just the GTX3584RS turbine wheel profile.  At the exit a v-band outlet is integral with the casting with a perfectly machined mating surface for a tight seal with the downppie flange.


     Honeywell-Garrett has packed quite a few technical features into this tidy package of a turbo.  With 6 different configurations available with the various housings it should be simple enough to make the GTX3584RS work exactly as you need.  Any engine from around 2.0 liters up to almost 6.0 liters in displacement can produce 1000 HP with this turbo mounted up on an exhaust manifold.  For a twin-turbo system, any engine of 4.0 liters and larger can be fitted with a pair of GTX3584RS turbos.  Regardless of what your exact configuration is you will have one of the best responding turbochargers available pressurizing the plenum.

Honeywell-Garrett GTX4088R

     This second generation GTX3582R turbocharger is outfitted with some of the same features of the large-frame GTX turbos so you know the performance is excellent.  The casting of the compressor housing is better than ever and it packs some race-ready features you will enjoy.  Being built around an 8mm turbine shaft which sits in ceramic bearings, it spins up to speed with very little measurable friction at all.  Honeywell-Garrett surrounds the shaft with a coolant filled housing to keep the temperatures low during operations.  On the hot side of the GTX3582R you have a plethora of options for housings.  There are T3 Housings, T4 housings, and v-band inlet housings options too.  This is one of the most popular turbochargers available to the performance aftermarket so this vast array of housing choices means everyone can get just the right housing configuration they need.


     Center stage is a dual ceramic ball-bearing cartridge that not only precisely centers and supports the turbine shaft, but it easily bears the thrust loads of the compressor wheel as well.  It is widely well-known that the dual (ceramic) ball-bearing turbochargers are quite durable with higher boost pressure loads.  Whereas the typical journal bearing turbocharger may be durable at 25 -35 psi, a comparable ceramic ball-bearing turbo will have no problem dealing with 35 - 45 psi on a daily basis.  Surrounding this bearing cartridge is a water-cooled housing.  By hooking up hoses from your engine’s coolant supply to the inlet and outlet ports of the GTX3582R’s housing you can keep bearing temps down and reduce carbon buildup in they turbine section of the turbocharger.  The shaft on the GTX3582R has a high-flow 84-trim 68mm turbine wheel.   This turbine wheel is critical to the GTX3582R having the optimal combination of high shaft speed and rotational torque to spin up the compressor wheel quickly.  On the other end of this shaft is a redesigned masterpiece of CNC-machining, the 66mm billet aluminum alloy compressor wheel.  It is a 10-blade 64-trim design redesigned for higher flow rates and better aerodynamic efficiency of the previous version.  It features a 76% peak efficiency and maintains more than 70% efficiency throughout its compressor map operating range.


     Honeywell-Garrett has outfitted the GTX3582R with a re-engineered compressor housing for expanded airflow.  The inlet has a fully machined anti-surge entrance into the compressor wheel blades for the air to have an efficient pathway.  There is a pre-machined speed sensor port in the housing so that compressor wheel rpm can be data-logged if desired.  A large 2.5” outlet is cast into this .70 A/R housing.  The inlet to outlet area ratio is key to the 850 HP level of airflow which is possible with the compressor wheel.  Even the casting process has been improved to offer a smoother surface finish on the exterior and the interior passages of the compressor housing contributing to the improvement in airflow capacity.


     On the hot side of the GTX3582R sits a wide range of turbine housings, (3) T3 flanged housings, (3) T4 flanged housings, and (3) v-band inlet housing choices.  Each housing is cast in a high-Nickel content Stainless steel alloy for improved durability at high-temperatures. All of the housings now feature a high-flowing v-band outlet configuration.  The T4 housing configurations are offered in .63 A/R, .82 A/R, and a 1.06 A/R, while the T3 housing choices are .63 A/R, .82 A/R, and 1.06 A/R, and finally the v-band housings offered are .61 A/R, .83 A/R, and a 1.01 A/R.  These 9 options make the boost curve tuning much easier With the smaller .61 and .63 housings best for rapid turbine acceleration and the 1.01 and 1.06 housings optimized for ultimate compressor flow volume capacity.  All of these offer class-leading turbocharger response which can be adjusted to suit the traction available or engine response criterion.  There are no bad choices with these turbine housings merely a change in tne character of its response.


     With all of the new features amount to a high-horsepower capable turbocharger with incredible responsiveness.  The GTX3582R will support 850 HP in a single turbo setup and 1700 HP with a pair bolted onto the exhaust manifolds.  Any engine from a modest 2.0 liter up to almost 5.0 liters will have nearly instantaneous boost response with a single GTX3582R.  With a pair of GTX3582R turbos from 4.0 liters through close to 10 liters can be accommodated perfectly.  With the compact water-cooled bearing section and short overall dimensions it can be put just about anywhere you prefer in the engine bay.  


Included Features:

Honeywell-Garrett Medium-Frame Competition Turbochargers

     The Honeywell-Garrett GTX4088R delivers large-frame performance with a small frame footprint.  This dual ball-bearing turbocharger can deliver 850 HP worth of airflow in an efficient manner with its combination of an anti-surge compressor housing and twin-scroll turbine housing.

     The GTX4088R has fairly compact dimensions for a turbocharger capable of well over 700HP.  This T4 turbocharger features a compact water-cooled bearing housing for its ball-bearing supported shaft.  An anti-surge compressor housing keeps the billet wheel operating in the ‘sweet spot’ of it efficiency as well.  Both turbine housing options feature twin-scroll inlets for unparalleled gas efficiency for the turbine wheel.


     The heart of this turbocharger is a shorter turbine shaft than that of the large-framed turbos with a similar bearing journal thickness.  This directly translates into a stronger shaft and more compact turbocharger dimensions.  This GTX4088R has a dual ceramic ball-bearing cartridge which guarantees both stellar responsiveness and durability at high boost pressures alike.  Around the ball-bearing cartridge is a water-cooled housing with a pair of large ports for coolant to flow into and out of.  Keeping the bearing temperature low is a simple affair with this housing being plumbed into the engines coolant lines.  This also greatly reduces the possibility of carbon buildup in the turbine housing heat shield area.  With the very low friction of the ceramic bearings and their ability to handle extremely high thrust load capacity, the GTX4088R has no problem coping with more than 2 or 3 BAR boost pressures.  The compresor wheel is 65mm at the inlet and 88mm in overall diameter.  This being a forged aluminum alloy and CNC-machined from a old billet it has very strong blades with much lower mass than a cast compressor wheel of similar dimensions.  It’s 11–blades are responsible for both the fast build-up of boost pressure in the compressor housing discharge and an impressive high 78% efficiency peak.


     The GTX4088R compressor housing has a large 4” inlet surrounding the anti-surge porting which is integrated into the compressor inlet cavity.  To help keep the compressor housing width as narrow as possible the discharge scroll is a slightly oval shape internally even though it features a rather large .72 A/R.  The discharge of the compressor scroll is a generously sized 2.5” and exits closer to the center axis of the turbocharger for a more compact housing profile.


     The 78-trim 77mm turbine wheel spins away inside of your choice of 4 twin-scroll housings.  Honeywell-Garrett elected to outfit the GTX4088R with a dual scroll turbine housing for the purpose of ensuring excellent turbine wheel acceleration characteristics.  The ability of the two scrolls to create a swirling motion of the incoming gas streams actually works to speed-up velocity just before interacting with the turbine wheel blades.  The net result is a measurable improvement in turbine shaft acceleration with a given volume of exhaust gas flow.  The smaller .85 A/R and .95 A/R housings afford the very best response with the GTX4088R, while the larger 1.06 A/R and 1.19 A/R housings allow for more peak airflow, and of course, midrange and top-end power.  Another feature include on each of the housings is the integration of a machined v-band flange into the turbine discharge outlet.  This keeps turbulence to a minimum and assures a leak-free connection to the exhaust downpipe which can be attached at any angle necessary.


     You can easily fit the GTX4088R onto a wide variety of engines from a 2.0 liter 4-cylinder or inline 6-cylinder, all the way up to a 6.0 liter V8.  A single turbocharger is ideal for most engines of more modest displacement while the GTX4088R’s excellent response capabilities allow for a pair to be utilized on an engine which is 4.0 liters or larger.  Be forewarned, a pair of GTX4088R turbos will shove 1700 HP worth of pressurized air into the plenum at full boost very quickly.

Honeywell-Garrett GTX3584RS

Honeywell-Garrett GTX3582R

Honeywell-Garrett GTX5018R

     The *BRAND NEW* GTX5020R offers up a 9% improvement in flow with a specilally designed selection of  bilet compressor wheels and housings which can support more than 2000 HP from a single turbocharger.  It features a proven dual ball-bearing CHRA for class-leading response, consistent performance, and durability.

     Honeywell-Garrett went back to the drawing board to coax even more performance out of the GTX5018R turbocharger and this is the spectacular result of their efforts.  The entire compressor section has been significantly altered to maximize the amont of airflow volume that can be moved with a 76mm, 80mm, and 88mm inducer compressor wheel. When combined with a 99mm turbine wheel the 88mm GTX5020R can support an incredible 2020 HP! 


     The GTX5020R CHRA has been tweaked  so much that the backplate, compressor housing, and of course the billet compressor wheel, are all new for this particular turbocharger.  The larger outider diameter of the compressor wheel sounds like a simple adjustment, but it necessitates a redesign of the backplate and the compressor housing for proper clearances to be maintained.  The billet aluminum alloy compressor wheel has a unique 2nd Gen 13-blade design similiar to the GTX5533R compressor wheels.  Coaxing more airflow out of a compressor wheel by nearly 10% is one thing, but reducing wheel mass by 30% is pure magic.  This redesigned compressor wheel is even faster to respond by a significant margin even with the higher airflow capacity.  The GTX5020R has a 84-trim 99mm turbine wheel supported by Honeywell-Garrett's largest ceramic ball-bearing assembly to date.  These are housed inside a finned casting that  offers additional surface area for cooling and plenty of material for strength and rigidity around the turbine shaft.  Bolted to the compressor end of this bearing housing is a billet aluminum backing plate which has been specifically CNC-machined to offer a weight savings and the proper clearance for the compressor wheel.


     To get the huge bump in airflow capacity from the compressor housing to complement the GTX5020R compressor wheels Honeywell-Garrett recast the housing with a larger .88 discharge to inlet area ratio.  Simply making the compressor wheel larger would not account for the 2000 HP airflow capability alone.  This housing has a fully machined anti-suge inlet cavity and the discharge has been precision machined as well for a high-pressure capable v-band flange connection.  As with the other housings in this GTX Gen-2 category, a speed sensor port has been machined into the housing base so that data-logging of the wheel acceleration can be recorded.


     At the all-important turbine end of this turbocharger sits a T6-flanged v-band exit housing in 2 size options from Honeywell-Garrett.  These housings offer a peak effiiency of 76% and are offered in both a .96 A/R and a 1.39 A/R open-volute configuration.

Even with just these 2 options you can use this turbocharger on an engine anywhere in the 2.8 liter to 11.0 liter range of displacement, this is a direct reflection of the highly efficient exhaust housing arrangement of the GTX5020R turbocharger.


     When Honey-Garrett put their resources together they produce impressive results like this GTX5020R turbocharger.  A rock-solid 2000 HP plus delivery from a 88mm turbocharger with great response, this shows where turbocharger technology has been brought to today.  Even a modest displacement 2.8 liter engine will spool this turbocharger up well, thanks to the state-of-the-art CHRA specifications.  A pair of these are just what the doctor ordered for a 4000 HP engine buildsheet, with airflow to spare.  What a turbo the new GTX5020R is.

Honeywell-Garrett GTX5020R

Honeywell-Garrett GTX3582R (Reverse Rotation)

This is a reverse rotation GTX3582R for twin turbocharger installations.  Honeywell-Garrett went through the trouble and expense to design an exact aerodynamic copy of the GTX3582R which flows in the opposite (counter-clockwise) shaft direction.  Same spectacular 66mm billet compressor wheel and dual ball-bearing shaft support.  The exact same class-leading boost response and 850 HP airflow deliver, just in a reverse orientation.

     For a perfectly symmetrical 1700 HP turbocharger fitment this (reverse rotation) GTX3582R can’t be be beat.  Thes exact same advanced compressor wheel design and housing tweaks are offered.  For tuning the response curve the 3 v-band options are covered to avail a completely v-banded and mirrored-image turbocharger system.


     The CHRA is built around the same ceramic ball-bearing supported turbine shaft assembly but with counter-clockwise blade profiles and a matching billet compressor wheel.  The same ultra-compact water-cooled bearing housing is used as the GTX3582R turbocharger so plumbing of the coolant lines and oil supply and drain will be easy.  The CHRA rotor group is fully VSR balanced to the same high standard (as with all of the GTX-R turbocharger CHRAs) for fitment into the turbine and compressor housings.  


     Identical in aerodynamic performance to the clockwise rotation standard GTX3582R compressor housing, the reverse rotation housing boasts the same advanced features and critical machining as the GTX3582R.  The speed sensor port is pre-machined into the housing shrouded inlet and the anti-surge inlet has been machined to the same specifications and tolerances.  It should be noted that to guarantee a perfect match to a standard rotation turbocharger, precision CNC machining of the compressor wheel and housing is the only way to produce the repeatable aerodynamic performance for a turbocharger manufacturer.  Honeywell-Garrett has this capability.  One look at the compressor wheel or it’s housing will reveal the precise machining Honeywell-Garrett has applied to making these ‘mirror-image’ GTX3582R turbos an exact copy of their standard rotation counterparts.


     Three exhaust housings are made available for this turbocharger, which of course has standard rotation matches for a perfectly symmetrical turbocharger setup.  The same .61 A/R, .83 A/R, and 1.01 A/R volume ratios are available in a reverse rotation v-band cast Stainless Steel housing.  Each of these housings are precision cast and machined with a v-band connection flange out of a high Nickel-content alloy perfect for high-temperature turbine housing use.  These 3 options allow a boost response curve to be established that will allow you to easily match up a pair of these mirror image turbos to an engine of about 4.0 liters of displacement or more.  The smaller .61 A/R ratio is better suited to the smallest engine builds or for the most responsive power delivery possible, while the 1.01 A/R would allow for the most airflow potential and the ability to support a full 1700 HP from the engine with a smooth power curve.


     Because Honeywell-Garrett has gone through the hassle to design this turbocharger a twin-turbocharged engine can actually look balanced aesthetically in addition to performing the way it should with no difference between 2 banks of cylinders being fed by a different turbocharger.  There is no guesswork with choosing how to the run the exhaust manifolds or charge piping, it can simple be a copy of the other side of the system.  This reverse rotation GTX3582R will allow you to cleanly mount a twin-turbo system on your engine and both turbos will operate EXACTLY the same or as if you had just one plumbed into the plenum.


Included Features:


 - Ceramic ball-bearing CHRA

 - Water-cooled bearing housing

Honeywell-Garrett GTX3576R

     With a cool 750 HP airflow delivery the GTX3576R brings large turbocharger performance to a small frame size.  Second generation compressor aerodynamics ensure quick boost buildup and a ball-bearing core guarantees responsiveness.  The '35R' has been recognized the world over as a solid platform for single or twin-turbo builds that require the very best engine response with high engine output.  The billet compressor wheel GTX3576R takes it to the next level.

Honeywell-Garrett GTX3576R

(Reverse Rotation)

     Honeywell-Garrett makes it easy to have a very balanced and perfectly symmetrical twin turbo system on a modest-displacement engine with the availability of the Reverse Rotation GTX3576R turbocharger.  The CHRA is equipped with a turbine wheel and compressor wheel which rotate counter-clockwise within their housings which are also specifically cast and machined for a balanced fitment with a standard rotation GTX3576R turbocharger.


     Honeywell-Garrett uses their proven dual ceramic ball-bearing cartridge to support the GTX3576R turbine shaft inside of a water-cooled bearing housing of compact dimensions.  The internal passages allow a consistent flow of coolant to circulate around the bearing cartridge and close to the turbine wheel end of the turbocharger, thus keeping the turbos oil supply from breaking down because of too much heat introduced by the turbocharger itself.  Carbon buildup is also dramatically reduced by the cooling effect in the turbine area of the bearing housing.  A rather healthy 68mm turbine wheel spins away inside the housing generating extremely vigorous compressor wheel acceleration on the opposite end of the shaft. The 58mm compressor wheel is a highly efficient 8-blade billet aluminum CNC-machined piece of precision aerodynamic form. This forged aluminum compressor wheel is freshly designed to surpass the previous design in both airflow volume and boost response. The 58-trim compressor wheel has a 76mm outer diameter and larger blade area. By altering the design to incorporate a smaller blade count but with increased surface area, Honeywell-Garrett has not just raised to airflow capacity, but reduced the wheel mass as well.  This results in a win-win situation of higher horsepower levels supported with faster response to the throttle inputs.


     The GTX3576R has a full 4” compressor inlet but the housing is smaller than the GTX3582R’s compressor housing by about an 1” for a smaller installation footprint in the engine bay.  It features a machined anti-surge inlet for the compressor wheel and a speed sensor port pre-tapped at the base of the compressor wheel outer diameter.  Now turbocharger speed can be data-logged for review after a run to get an accurate picture of the map efficiency your setup has. The compressor discharge is a 2” opening and has better internal flow dynamics from improved casting methods applied to the housing.  The entire housing has been cast in a mirror image of a standard rotation GTX3576R and precisely machined to offer the same aerodynamic performance but with an output facing the opposite direction from the compressor discharge.


     This turbocharger has the same turbine wheel as the larger GTX3582R turbo and has the same generous housing choices available to make the GTX3576R responds exactly the way your engine best requires.  The 84-trim turbine wheel really make this turbocharger a powerhouse of boost delivery.  The housing choices allow you to mount this to a fully v-band flanged exhaust manifold with a few A/R options for boost response and power delivery curve tuning. The smaller area .61 A/R housing will produce the fastest boost response possible from the engine.  Conversely, the larger area 1.01 A/R housing will make the best top-end power possible.  Each housing inlet flange is precision-machined for a tight seal to the manifold.  These housings are also cast from a high-Nickel content Stainless Steel alloy for superior high-temperature durability, perfect for a high-output 1500HP capable engine.


     A pair of GTX3576R turbochargers will deliver instant boost response from low engine speeds like few turbochargers can. This particular combination of compressor wheel and turbine wheel supported by twin ball-bearings affords killer response and a strong top-end delivery potential.  Combining 2 GTX3576R turbos together on a 4.0 liter or larger has the capability to unleash 1300 WHP and more from the engine.  These are serious turbos.  With the aerodynamic technology and precision-machining Honeywell-Garrett has invested in the Reverse Rotation GTX3576R it makes setting up a big HP, smaller engine for boost a very balanced and great-looking affair.  Most engines will enjoy using mirror-image exhaust manifolds, downpipes, charge piping, and CAI piping for the ultimate in symmetrical layout.

     Featuring a dual ball-bearing core with state-of-the-art compressor and turbine wheels with numerous turbine housing options, the 2nd generation GTX3076R is a tough turbo that performs extremely well and is easy to setup correctly. Very few turbochargers can generate 750 HP from an engine under 2.0 liters which is exactly what the GTX3076R can do. Honeywell-Garrett have shown us that aerodynamics are key with making small turbochargers capable and efficient at moving large masses of air.


     At the core of the GTX3076R turbocharger is a dual ceramic ball-bearing CHRA with a 58mm compressor wheel on one end and a 60mm turbine wheel on the opposite end. The bearing cartridge sits inside a water-cooled bearing housing that keeps the oil temperatures in check and reduces the occurrence of carbon deposits near the turbine wheel. This single feature extends the life of the GTX3076R by reducing the effects of heat on the oil flowing through the ball-bearings. Since the forward ceramic ball-bearing also bears the compressor thrust loads, the GTX3076R has a very high capacity for boost pressures which would wear out most journal-bearing turbochargers. Honeywell-Garrett redesigned the billet aluminum compressor wheel to incorporate a 9-blade arrangement that has lower mass and larger blade area at the same time. This CNC-machined forged aluminum wheel is blessed with expanded airflow capacity AND faster response. Aerodynamics being applied well are what we have with the GTX3076R turbocharger. The turbine wheel itself is also an advanced work of thermodynamic efficiency. It may be smaller than other GTX turbine wheels but its profile is perfectly shaped to move very efficiently in the exhaust gas stream of the GTX3076R turbine housings. The turbine wheel’s low mass has an important advantage, it gives a measurable acceleration boost to the response of this turbocharger. All said, the CHRA of the GTX3076R is tough, compact, and extremely well-suited to offering class-leading responsiveness.


     The compressor housing that surrounds the billet wheel so well on this turbocharger has been subjected to some tweaks as well. First, the inlet of the compressor housing has a precision-machined anti-surge cavity to protect the compressor wheel from damage and broaden the efficiency of the GTX3076R’s performance. Second, the housing has been pre-tapped for a speed sensor right at the base of the outer blades of the compressor wheel. Now you can accurately data-log the shaft speed during a run to gauge the turbocharger setup efficiency an keep watch for an over-speed condition. The third alteration is an improved casting of the entire housing for smoother surfaces both external and more importantly for airflow efficiency, internal. The .60 A/R housing is specifically cast with just the right scroll volume to promote very rapid boost build-up within the compressor housing. The engineers have labored long and hard on making the GTX3076R compressor section deliver massive amounts of pressurized air, quickly.

The options for the turbine housings are extensive and include (6) T3-flanged housings in either wastegate configuration or ‘free-float’, and (3) different full v-band housing choices. The T3 housing options are available with either a v-band turbine outlet or a 5-bolt arrangement designed for the wastegate configuration. T3 housing choices are .63 A/R, .82 A/R, and 1.06 A/R in either outlet style. The v-band housings have a different set of volume ratios, a .61 A/R, .83 A/R, and a 1.01 A/R. The v-band housings are cast in a high Nickel-content Stainless Steel alloy for superior heat resistance and durability. No matter what your preference is for boost regulation, Honeywell-Garrett has you covered for the GTX3076R. Ideally, the .61 and .63 A/R housings allow for the most responsive boost delivery possible, and on the other end of the spectrum, the 1.01 and 1.06 A/R housings will deliver the highest airflow and top-end flow potential.


     The range of engine displacement best matched by the GTX3076R are between 1.8 liters and just over 3.0 liters for a single turbocharger system. Twin-turbo systems for 3.5 liter engines and larger will have excellent response with a pair of GTX3076R turbos bolted onto the manifolds. With a combined output of 1500 HP these twin-turbo systems will surely get plenty of respect from a competitor. Especially after you spool-up in an instant and rocket away at warp-speed.

Honeywell-Garrett GTX3071R

     The second generation GTX3071R ball-bearing turbocharger delivers 675 HP in an instant.  It combines a next-generation compressor section with a proven ball-bearing supported shaft and numerous turbine housing options for a potent small engine displacement turbocharger that delivers big horsepower numbers.  Highly-efficient and fast-responding, the GTX3071R is packed with advanced features and outstanding performance capabilities.

     Looking at the cold side of the GTX3071R turbocharger you will see a newly designed compressor housing which has been machined in key areas to expand upon its performance envelope. The inlet to the compressor wheel has been precision-machined with anti-surge porting surrounding the wheel inducer. Outside of the housing is a port machined into the base of the compressor wheel area for an optional speed sensor. Honeywell-Garrett has performed this step with extra-careful precision so that the compressor wheel outer blade edge speed could be recorded and logged during a run for later analysis if needed. Speaking of compressor wheels, this one is a beauty. It has a lower-mass 8-blade design which features higher airflow capacity AND faster response. This CNC-machined billet aluminum compressor wheel has a 54mm inlet diameter and is 71mm in outer diameter width. Very modest dimensions for nearly 70 lbs per minute of airflow potential indeed. This ‘Gen-2’ wheel is key to the GTX3071R having such incredible horsepower delivery capability. The compressor housing has been tweaked to offer stellar boost response as well with a .60 A/R. Even the casting itself has been reworked for a smoother internal passage consistency and exterior finish.

  

     The heart of the GTX3071R is its 60mm turbine shaft spinning inside of a dual ceramic ball-bearing cartridge. Cast in Inconel alloy, then precision-machined and balanced, this turbine wheel has a low-mass shape to its blades with a high-flowing profile Honeywell-Garrett has extensively developed for ball-bearing turbocharger service. Proven to be ultra-precise for keeping the compressor wheel spinning dead-center inside the housing, the twin ceramic bearings also support high thrust loads imposed by high boost pressure. Compared to a comparable journal bearing turbocharger the ceramic ball-bearing turbos are able to live at much higher boost pressures. It is common to see more than 2 BAR boost pressure without any issues from these turbos. The bearing housing itself iOS cast with a cavity surrounding the bearing cartridge for coolant to circulate through. Water-cooling the turbocharger like this keeps the oil circulating through the bearings from breaking down chemically due to the heat of the turbocharger exhaust gasses radiating through the housings. The cooling effect also dramatically reduces the likelihood of carbon deposits forming in the turbine housing end of the bearing casting assembly.


     The turbine housing options available for or the GTX3071R turbocharger are (6) T3-flanged choices and a trio of full v-band housings for the 60mm 84-trim turbine wheel. With nine options for turbine housing configuration finding just the right one for your engine and fitment requirements is a simple affair. For the T3 housings you have the choice of a .63 A/R, .82 A/R, or a 1.06 A/R with either a v-band outlet or a 5-bolt wastegated configuration. The v-band housings offer a choice of a .61 A/R, .83 A/R, or 1.01 A/R. These v-band housings are unique in both internal volume and their high-nickel Stainless Steel alloy composition, being specifically cast in this alloy for extra-durability at high temperatures. For tuning the GTX3071R for the best responsiveness the .61 and .63 A/R housings are best. On the opposite end of the housing selections, you will find the 1.01 and 1.06 A/R options best for the ultimate levels of top-end airflow potential from the GTX3071R turbocharger. All of these housings are designed just for the GTX3071R turbocharger’s 60mm turbine wheel profile.


     Depending on the turbine housing selection you choose, you will enjoy phenomenal boost response with an engine as small as just 1.5 to 1.8 liters of displacement. The upper edge of the GTX3071R’s performance will deliver a very respectable 675 HP. A pair of GTX3071R turbos can pressurize a 3.0 liter or larger engine to the tune of a cool 1350 HP. No matter how you use the GTX3071R you will be thoroughly pleased with the responsiveness of its trick, dual ball-bearing supported, next-generation compressor wheel aerodynamics. The output supported by this new-and-improved turbocharger is worthy of respect to be sure.

Honeywell-Garrett GTX2976R

     Having a 600 HP plus capability from a fairly small turbocharger that doesn’t require a large engine displacement is what the GTX2976R is all about. Take a tough ball-bearing CHRA with a sweet 58mm billet compressor wheel, which is spun up to speed by a highly efficient 57mm turbine wheel, and house it within a set of well-proportioned housings on each end, and you get the responsive GTX2976R.


     Honeywell-Garrett has masterfully engineered the ball-bearing cartridge to the point that it is a proven core for their highest output turbochargers. After several years of development the ceramic ball-bearing supported turbine shafts are a ‘known entity’ in the performance aftermarket turbocharger arena. Using ceramic balls to deal with the extremely high rpms and the heat loads is key to each of their applications. The incredible performance of this GTX turbocharger showcases this very well. The 78% efficiency peak of the compressor map is strong evidence of how well the GTX2976R works at moving air. Honeywell-Garrett has a great combination here for smaller displacement engines. A water-cooled bearing housing surrounds the bearing cartridge with coolant to keep the oil from breaking down from within the turbocharger core. Carbon deposits in their turbine housing area are greatly reduced by this cooling of the bearing housing as well. The 57mm turbine wheel associated with this GTX2976R turbocharger is a high-rpm high-flow profile appropriate for the extremely high shaft speeds common with a ball-bearing turbocharger. The blade shaping has been developed by Garrett to respond best with a highly responsive ball-bearing CHRA. The 11-blade forged aluminum compressor wheel being driven on the other end is a proven Gen-1 design that offers low mass and very high flow rates alike. Offering close to 80% aerodynamic efficiency is no small feat, Honeywell-Garrett have invested thousands of man-hours into developing their GTX compressor wheels to such a high standard. The GTX2976R would not be nearly as good without it.


     For the compressor housing on this turbocharger, a large inlet casting with an anti-surge cavity and machined slot was specially fitted. On this casting the majority of the inducer area has been precision-machined for the best aerodynamic properties and consistent airflow dynamics. The outlet scroll is a .60 A/R and offers very fast boost build-up within the housing form the airflow being compressed by the billet wheel. On the inlet there is a large 4” opening to support plenty of incoming airflow to feed the hungry compressor wheel as it quickly accelerates up to speed. This is a very effective housing as far as both airflow and surge-resistance. The 2” outlet is an easy connection to make to the charge piping as well.


     On the all-important turbine side of the GTX2976R CHRA we find a selection of different housings which make setup and boost response tuning easier. There is a .64 A/R internally wastegated housing with a 4-bolt T25 flange on the inlet offered to get excellent turbine wheel acceleration and incredible midrange airflow capability as well. A trio of full V-band flanged housings are also available for this turbocharger with turbine area options from the smallest of .61 A/R to the largest of 1.01 A/R. This affords a great range to adjust the boost response and power delivery to your preference. The smaller A/R housaings are ideal for the absolute fastest turbo response possible and the largest will support the most airflow (and therefore HP) potential from the GTX2976R.


     There are so many applications for a turbocharger such as this because of its immense capabilities. Flowing enough air to support just over 620 HP is quite serious, especially considering how small this turbocharger assembly is. The compressor housing itself, which is the largest single component of the GTX2976R, is only about 8” wide. With the internally wastegated turbine housing the packaging can be very tidy indeed. Since an engine of merely 1.8 liters has no problem whatsoever spooling this turbocharger up quickly, there are countless applications for either upgrading a factory-turbocharged or a custom-built turbo engine. If prefered, a well-built 3.0 liter engine can get a pair of GTX2976R turbos to sing their ‘war cry’ quite well to the tune of nearly 1250 HP! All of this potential is at your disposal with some of the fastest turbocharger spool-up response you can imagine.

     With the abilty to support more than 600 HP and being having some compact dimensions, the Honeywell-Garrett GTX2976R is a great turbocharger for smaller displacement  engines.  It has the added benefit of being a great upgrade turbocharger for many factory turbocharged engines.  The best way to describe this turbo is to qoute Muhamed Ali..."it floats like a butterfly and stings like a bee".  Ok, so it spools like a... you get the picture.  The GTX2976R has fast response and great airflow for serious power.

Honeywell-Garrett GTX5009R

The Brand New GTX5009R turbocharger offers up from nearly 900 HP to 1700 HP from your choice of either a 76mm or 80mm advanced aerodynamic profile billet compressor wheel.  This ball-bearing turbocharger features a fully updated compressor section being driven by a highly-efficient 99mm turbine wheel. The GTX5009R delivers huge amounts of airflow from this combination of state-of-the-art compressor aerodynamics and large high-gas-flow turbine wheel .

     A full ball-bearing supported turbine shaft has on the hot side a 99mm turbine wheel which spins a 109mm diameter compressor wheel on the cold side of the GTX5009R turbocharger.  The aerodynamic improvements made to the compressor wheel profile account for a substantial 15% increase in airflow capacity throughout the operating range of the GTX5009R.  This Gen-2 compressor wheel is matched to an improved compressor housing with top-notch machining and improved features for competitive use. 


     At the very core of this new offering from the engineers at Honeywell-Garrett is a ceramic ball-bearing housing with some advanced features of its own.  The dual ball-bearing structures is key to an accurate shaft alignment within the housings and very high thrust load capacity for those competitive levels of boost pressure expected of these turbos.  The bearing housing itself is a sturdy casting with very prominent fins on its exterior strategically placed to increase surface area for cooling of the bearings held within.  Honeywell-Garrett is quite adept at turbine wheel thermodynamics to be sure with experience going back several decades and their choice for the best performance is a 99mm Inconel turbine wheel.  This turbine wheel features Garrett’s signature blade profile which is very thick close to the center of the shaft and much thinner at the outer edges.  This greatly reduces mass for the exhaust gas stream to act upon.  A closer inspection of the blade shape reveals that each blade has a slight curvature away from the shaft and downward to open up the distance from each blade to the next.  This strategic shaping allows higher gas flow from between the blades as it exits away from the turbine wheel, most beneficial for reducing unnecessary back pressure or choke-flow.  On the other end of this shaft sits the jewel of the GTX5009R, its 13-blade, forged billet aluminum, CNC-machined compressor wheel.  Redesigned from the shaft area out to the tips, this new wheel offers much more blade area with a smaller base for lower mass to be spun-up to speed.  So much has been done to reduce inertia on this wheel that the nut to secure it to the turbine shaft is actually a part of the aluminum compressor wheel.  How much is this effort worth?  This amounts to 39% lower compressor wheel inertia, which is directly related to how fast this GTX5009R can respond and accelerate.  Very trick indeed.  Taking it one step further, the backing plate of this turbo is actually a billet aluminum precision-machined component, also designed to shed weight from the turbocharger.  It is both strong, light, and has a new o-ring seal for the compressor housing to clamp down onto.  This is to keep the high boost pressures from escaping from between the housing and plate connection.  From the turbine wheel to the compressor wheel this CHRA is packed with cutting-edge features for assuring the best performance possible.


     Added to the compressor wheel is a new housing that has a few features of its own to complement the performance improvement of the GTX5009R.  Looking into the compressor inlet you get to feast our eyes on some very precise machine-work to give the inlet anti-surge protection.  The expanded compressor flow dynamics get a boost from this inlet being contoured in specific places and exactly proportioned around the compressor wheel inlet.  The casting itself is a fresh one with smoother surfaces on the exterior and more importantly, the internal passage of the compressor discharge.  The discharge features a larger .88 A/R volume ratio to improve airflow being delivered from the compressor wheel.  There is a v-band flange on this discharge outlet for a high-pressure connection to the charge piping.  Another new addition to the compressor housing is a fully machined speed sensor port right at the base of the compressor wheel blade tips.  Now you can easily attach a sensor and properly monitor the turbocharger speed during a run to analyze your housing selection and keep tabs of the turbochargers performance parameters.


     Honeywell-Garrett offers a pair of turbine housings to suit the GTX5009R.  Both of these housings are an open volute/scroll inlet configuration with a v-band outlet.  These housings were designed to offer the high levels of gas volume the 99mm turbine wheel requires for optimal performance.  The smaller area .96 A/R housing offers the fastest turbo response possible no matter which compressor wheel size you have, while the larger volume 1.39 A/R housing delivers the maximum amount of compressor flow and horsepower levels possible.  Both housings have precisely machined v-band flanges for the downpipe connection offering a low-turbulence exit for the exhaust gasses out of the turbine wheel.


     With the 2 compressor wheel sizes and 2 turbine housing choices you have 4 options available to custom-tailor the GTX5009R to your use.  The GTX5009R has some incredible features making it an easy choice for either single turbo or twin-turbo engines.  These turbos don’t require much exhaust energy to get them up to speed because of the highly-efficient compressor section and low-friction ball-bearing CHRA.  A mere 2.5 liter engine can have a single (76mm) GTX5009R fitted and deliver up close to 1000 HP, and a small displacement V-8 can have incredible turbo response and around 2000 HP with (2) 76mm GTX5009R’s.  With the larger 80mm compressor wheels a pair of GTX5009R turbos can support an impressive 3400 HP.  This is Pro-Mod territory for certain, not for the faint of engine, or chassis.

Honeywell-Garrett GTX4720R

     Introducing the GTX4720R 1950 HP capable turbocharger.  This turbocharger is a dual ball-bearing turbocharger which offfers superior aerodynamics from its redesigned 76mm, 80mm, or 88mm compressor wheels.  Offerring lower inertia and dramatically expanded performance capability Because of the completely reworked compressor section, the GTX4720R gets the nod for taking it to the limit with a 93mm turbine wheel. 

     There are 3 different compressor wheel sizes you can have with a GTX4720R to support from just over 1000 HP to just under 2000 HP for quite a range of output from a single turbocharger.  Honeywell-Garrett accomplished this with an aggressively modified compressor section fitted to the GTX4718R turbine shaft.


     The foundation of this turbocharger is the combination of the high-flow 93mm turbine wheel and a larger 120mm diameter compressor wheel with reprofiled blades.  This rotor group is supported by a dual ceramic ball-bearing cartridge precisely located within the bearing housing itself.  The bearing housing has been cast with external fins to increase surface area for cooling of the bearing structure within.  Honeywell-Garrett uses this dual ball-bearing arrangement for 3 reasons.  The first is for keeping internal friction associated with the turbine shaft ultra-low.  Secondly, it keeps shaft alignment perfectly centered and assures both the compressor and turbine wheels run exactly at the center of their housings for best aerodynamic performance and efficiency.  Finally, for higher thrust load capacity for continuous operations above 3 and 4 BAR boost pressure which this turbocharger will spend the majority of its life at.  Attached to the ‘cold’ side of the bearing cartridge is a billet aluminum fully-machined backplate that is lighter than the older cast iron plates and just as strong.  This aluminum backplate also has an o-ring seal for the the interface with the compressor housing itself to keep he entire assembly free of potential boost leaks.  This was a costly addition to retool for, but Honeywell-Garrett felt driven to pursue weight reduction and improved durability wherever possible with their larger turbochargers.  The compressor wheel is the star of the show with this turbocharger for good reason.  It is reprofiled to flow almost 10% more airflow throughout its operating range while being lower in mass.  It also offers a 30% reduction in inertia which is huge, thus allowing for even faster boost build-up and turbo response.  It is amazing what a handful of aerodynamic engineers and computer-controlled machining can accomplish with small adjustments to the dimensions of these components.


     The housing surrounding the compressor wheel is also altered to promote enhanced airflow.  The inlet cavity has a precision-machined anti-surge profile that extends the compressor map efficiency and gives a smoother path for the incoming air column entering the wheel.  The scroll itself has been recast with a larger .88 A/R area for better airflow volume with the improved compressor dynamics.  You also get a precision-machined speed sensor port and v-band discharge outlet flange.  Now you have all of the advanced features on the compressor housing for a proper data-log of the turbocharger during a run and a tight seal for the charge pipe connection.  The housing itself is the latest generation casting which has a much more uniformly smooth surface finish both on the exterior, and more importantly, the interior of the discharge scroll cavity.  The housing modifications of the GTX4720R are absolutely crucial to the outstanding performance it boasts.


     There are 4 distinct housing options for the 93mm 84-trim turbine wheel.  A .96 A/R housing is the smallest area housing available, while on the opposite end, a 1.39 A/R housing has the largest area.  For the best possible turbine (and therefore the entire rotor group) acceleration the .96 A/R is what you need.  The 1.39 A/R housing allows for the highest exhaust gas flow rates for the ultimate top-end power capability.  Since there are 2 housings sizes in between, you have plenty of boost response tuneability to work with.  Each of these housings features a high-flow single scroll inlet with a T6 flange pattern and on the outlet of the turbine discharge is a fully-machined v-band flange.  These housings were designed with competition in mind from the beginning with each casting having a high Nickel-alloy content for superior heat durability.


     Pairing up 2 76mm GTX4720R turbochargers has the potential of supporting a MINIMUM of 2050 HP with the smallest .96 A/R turbine housings.  This will represent the very fastest turbocharger response with a Pro-Mod setup.  Those engines built for 4000 HP will enjoy phenomenal responsiveness too even with the 88mm compressor wheel and 1.39 A/R turbine housings.  All of the GTX4720R variations are quick-responding because of the low-mass compressor wheel and ball-bearing supported turbine wheel.  You really can’t go wrong with this turbocharger no matter which level of compressor size you choose.

Honeywell-Garrett GTX4709R

The BRAND NEW 1625 HP GTX4709R takes the 80mm compressor wheel size to another lever of airflow.  Spectacular performance comes from a combination of a new compressor wheel and housing offering better flow and quicker response.

     To bring the 76mm and 80mm ball-bearing turbos to the next level Honeywell-Garrett made a concentrated effort at getting even more airflow out of the compressor wheel and redesigning the compressor housing to match it.

  The result of this effort is an impressive 15% improvement in airflow.  They also modified the compressor wheel for lower mass to improve response too.  These modifications really make these turbos shine.  


     The core of the GTX4709R is the dual ceramic ball-bearing cartridge that supports the 93mm turbine wheel and shaft assembly.  A finned bearing housing keeps the ball-bearing cartridge from getting too hot by wicking away heat from the bearings themselves. Using a dual ball-bearing system to support the shaft not only guarantees excellent response from the rotor group and precise wheel alignment within the housings, but assures class-leading thrust capacity for the high-boost loads imposed by completion use.  On the ‘cold’ end of the turbine shaft sits the magical new billet aluminum compressor wheel.  The forged CNC-machined wheel is  now 109mm in diameter, growing by 1mm, but most impressively is LIGHTER.  Even though it has more airflow capacity it boasts a 39% lower inertia improvement as well.  Both the 76mm and 80mm compresor wheels have the same aerodynamic advancement in this GTX4709R turbocharger.  This CHRA is now capable of delivering the same level of airflow as a 88mm CHRA because of the new compressor dynamics.  To top off the CHRA improvements Honeywell-Garrett includes a matching lightweight backing plate for the compressor housing to clamp down onto.  It is machined out of a similar aluminum alloy as the billet compresor wheel.


     All of the credit for this performance is not solely attributed to the compressor wheel.  The housing itself has been redesigned as well for more airflow capacity.  A .88 A/R has been incorporated into the casting dimensions to boost aerodynamic efficiency at higher airflow rates.  This new housing takes full advantage of the new compressor wheel‘s attributes to deliver the next-level of airflow from the 76mm and 80mm GTX4709R turbocharger.  At the compressor housing inlet we see a fully precision-machined anti0surge cavity for very efficient airflow ingestion into the compressor wheel inducer.  This machining is complemented by a speed-sensor port machined into the housing and a v-band outlet at the compressor discharge itself.  There should be no concern with boost pressure leaks on this turbo with the v-band connection.  The speed sensor port allows you to keep tabs on shaft speed and acceleration during a run to make sure you have the turbine housing A/R dialed in perfectly on your setup.  These turbos were designed from the outset for competition with these important features.  


     The hot side of the GTX4709R turbochargers is a full range of turbine housings which were also designed to work best around the 93mm Inconel alloy turbine wheel spinning away inside them.  These 82-trim housings all feature a v-band outlet precision-machined into the turbine discharge for a solid connection to the downpipe with low-turbulence characteristics.  The housing sizes range from a .96 A/R up to a 1.39 A/R with 2 sizes in between offering a wide range of turbine flow dynamics for tuning the GTX4709R response curve.  Whereas the 1.39 A/R housing will deliver the maximum amount of high-end airflow and HP possible the .96 A/R housing this the champion of getting the very best response out of the GTX4709R.  All of these options are merely for adjusting the boost curve for your engine and the track conditions.  The smaller A/R housings will surely test the traction of your chassis with their insane spool-up and lower-rpm and midrange delivery, while the larger A/R options ’soften’ the delivery somewhat but have similar boost build-up once spooled, even with smaller displacement motors.


     Honeywell-Garrett has been listening to competitors all over and responded well with the GTX4709R turbocharger.  It responds even better and delivers more HP everywhere in the rpm range.  None of the ball-bearing turbos were ‘laggy’ but these new advancements in compressor aerodynamics make the larger turbos respond like they were much smaller in size.  But who would consider a 1600 HP plus delivery from a 80mm turbocharger anything but ‘big-time’?  A pair of GTX4709R turbos will be right at home on a 2400 - 3100 HP Pro-Mod engine with plenty of responsiveness and midrange delivery to make great numbers on the big-end of the track.

  With a choice of either a 102mm or an even larger 106mm compressor wheel you know the BRAND NEW GTX5544R is one mean turbocharger.  A state-of-the-art compressor section, low-friction ball-bearing core, and ultra-high exhaust flow turbine wheel combine to give you all that Honeywell-Garrett has to offer with this top-of-the-line GTX5544R turbocharger.  Packed from end to end with advanced features, this turbocharger is ready to be run right into the winner’s circle.  

     The GTX5544R is the new ‘Bad-Boy’ ball-bearing turbo from the skunkworks at Honeywell-Garrett.  This turbocharger combines the highest flowing compressor wheel and housing arrangement with a massive 112mm turbine wheel for just one purpose, track domination.  Advanced machining of the compressor housing, compressor wheel, and backing plate make this compressor section 100% brand new.  Added to the very capable turbine section this means better airflow, faster response, and much improved track performance.


     Honeywell-Garrett went to great lengths to increase the airflow capacity of the (larger by 2mm) 120mm diameter compressor wheels for this turbocharger.  Just like their other Gen-2 compressor wheels, each blade profile is altered to reduce mass while expanding area for airflow volume improvements.  A very strong, aerospace-grade forged T6 aluminum alloy is used to make each of these wheels from a solid billet.  The CNC-machined wheels each have very precise dimensions and take maximum use of the amount of blade height that will work with the turbine shaft section protruding out of the backing plate.  The compressor housing associated with these massive wheels has its own features to add to making the GTX5544R a great turbocharger for competition.  The inlet area is fully precision-machined for a highly efficient anti-surge cavity.  Even the area leading into the wheel inducer itself is radiused by machining for the best airflow possible.  The housing discharge is a rather large .96 A/R for the ultimate in airflow volume.  The housing itself is improved with a casting method to yield a smoother surface finish both outside, and more important to aerodynamic function, inside the scroll passageway.  For monitoring the compressor wheel speed a fully machined sensor port is integrated into the compressor housing base.  The discharge is a v-band for a secure connection to the charge piping.  With all of these advances there are no doubts to the level of commitment Honeywell-Garrett has to making their GTX55 performance line of turbochargers the best available.

Honeywell-Garrett GTX5544R

GTX Ball-Bearing Turbochargers


State-of-the-Art Billet Compressor Wheels

Precision Housing Machining

Tough Ceramic Bearings

High-Flowing Turbine Wheels

 Proven Responsiveness

     This smaller-frame turbocharger has a compact footprint, a tough ball-bearing core, and large airflow delivery capabilities. Any engine from a 2.0 liter to just under 5.0 liters will be a perfect match for the GTX3576R and will deliver boost from low engine speeds through to redline. It combines a very efficient and generously sized turbine wheel with a state-of-the-art compressor wheel to deliver performance much higher than the compressor wheel dimensions would suggest are possible.


     Honeywell-Garrett uses their proven dual ceramic ball-bearing cartridge to support the GTX3576R turbine shaft inside of a water-cooled bearing housing of compact dimensions. The internal passages allow a consistent flow of coolant to circulate around the bearing cartridge and close to the turbine wheel end of the turbocharger, thus keeping the turbos oil supply from breaking down because of too much heat introduced by the turbocharger itself. Carbon buildup is also dramatically reduced by the cooling effect in the turbine area of the bearing housing. A rather healthy 68mm turbine wheel spins away inside the housing generating extremely vigorous compressor wheel acceleration on the opposite end of the shaft. The 58mm compressor wheel is a highly efficient 9-blade billet aluminum CNC-machined piece of precision aerodynamic form. This forged aluminum compressor wheel is freshly designed to surpass the previous design in both airflow volume and boost response. The 58-trim compressor wheel has a 76mm outer diameter and larger blade area. By altering the design to incorporate a smaller blade count but with increased surface area, Honeywell-Garrett has not just raised to airflow capacity, but reduced the wheel mass as well. This results in a win-win situation of higher horsepower levels supported with faster response to the throttle inputs.


     The GTX3576R has a full 4” compressor inlet but the housing is smaller than the GTX3582R’s compressor housing by about an 1” for a smaller installation footprint in the engine bay. It features a machined anti-surge inlet for the compressor wheel and a speed sensor port pre-tapped at the base of the compressor wheel outer diameter. Now turbocharger speed can be data-logged for review after a run to get an accurate picture of the map efficiency your setup has. The compressor discharge is a 2” opening and has better internal flow dynamics from improved casting methods applied to the housing.


     This turbocharger has the same turbine wheel as the larger GTX3582R turbo and has the same generous housing choices available to make the GTX3576R responds exactly the way your engine best requires. The 84-trim turbine wheel really makes this turbocharger a powerhouse of boost delivery. The housing choices allow you to mount this to a T3-flanged, T4-flanged, or even a fully v-band flanged exhaust manifold with a few A/R options for boost response and power delivery curve tuning. The smaller area .61 or .63 A/R housings will produce the fastest boost response possible from the engine. Conversely, the larger area 1.01 and 1.06 A/R housings make the best top-end power possible. Each housing inlet flange configuration has 3 A/R options for tuning.

A single GTX3576R will deliver instant boost response from low engine speeds like few turbochargers can. This particular combination of compressor wheel and turbine wheel supported by twin ball-bearings affords killer response and a full 750 HP top-end delivery potential. Combining 2 GTX3576R turbos together on a 4.0 liter or larger has the capability to unleash 1500 HP from the engine. These are serious turbos. With the aerodynamic technology and precision-machining Honeywell-Garrett has invested in the GTX3576R it makes a very big impression for its size.

(Reverse Rotation)

Honeywell-Garrett GTX2971R

     With an ultimate airflow capacity of 560 HP the GTX2971R has a good deal of airflow to be sure.  The dual ball-bearing supported 57mm turbine shaft offers class-leading responsiveness and durability.  Higher boost pressures over 2 BAR are no problem either.  Many turbine housings are available for the hot side allowing tuning adjustment and fitment options.


     The core of the GTX2871R is a dual ceramic ball-bearing CHRA enclosed within a water-cooled bearing housing.  The turbine shaft has a high-flow 57mm turbine wheel the offers an efficient transmission of thermodynamic energy into rotational shaft speed.  The GTX29712R has 2 options for turbine wheel trims.  The standard 84-Trim and a larger 90-Trim.  The exducer size is 2mm larger at 54mm on the 90-Trim turbine wheel.  Both turbine shafts have their strong points.  The 84-Trim is lighter and will spin up to speed faster, while the 90-Trim will support the compressor wheel best in high-HP applications.  This ball-bearing supported shaft is very precisely located and this is crucial for the compressor wheel and turbine wheel performance to be at optimum levels by keeping them exactly centered in their respective housings.  Honeywell-Garrett uses a proven bearing cartridge design with this series of turbocharger based on their lengthy development process.  These ball-bearing cartridges are well-known the world over as the gold standard of both performance and durability of turbocharger cores.  On the cold end of the shaft is a 54mm (inducer diameter) billet compressor wheel that offers an impressive 77% aerodynamic efficiency level.  CNC-machined to exacting precision, this 11-blade aerospace-grade aluminum alloy wheel is the key to the GTX2971R‘s performance levels.  It is both very low in mass and strong.  Much stronger than a cast-aluminum alloy compressor wheel.  The additional strength and blade rigidity is key to maintaining blade shape during the higher rpm levels associated with these ball-bearing turbochargers.  Total airflow capacity of this particular compressor wheel will support 560 HP.  Coupled to the high exhaust -flow capacity of the turbine wheel on the other end of the shaft, this CHRA is the reason this turbocharger responds so well and delivers such high levels of airflow.


     The compressor housing fitted to complement this compressor wheel is a large inlet diameter casting with a few design features that compliment the CHRA performance capabilities quite well.  At the compressor inlet, a 4” opening allows copious amounts of fresh airflow into the compressor wheel with little turbulence or drag.  Anti-surge porting is also incorporated into the inlet to extend the map efficiency of the compressor wheel and limit potentially damaging surge from ever being an issue.  The housing has some machining performed on the entry to the compressor wheel for keeping the airflow precisely uniform upon entry into the blades.  The outlet passage has been cast in a .60 A/R ratio for very fast build-up of boost pressure from the compressor wheel airflow.  This feature is a complement to the CHRA’s aerodynamic capability and contributes to a quick boost rise from the GTX2971R turbocharger.


     On the turbine wheel side of the GTX2971R there are a selection of well-engineered turbine housings to take full advantage of the available exhaust gas energy.  A pair of T25-flanged housings allow for an internally-wastegated turbocharger fitment making an installation very simple.  The (6) V-band housings are specially cast in a high-Nickel content Stainless Steel alloy for superior durability in high-output applications.  These housings are offered in 3 different scroll volumes for tuning, and you can select either a 84-Trim or 90-Trim turbine wheel with each housing size.  The .61 A/R is the optimal choice for the fastest turbocharger response possible, and on the other end of the scale the largest 1.01 A/R housing delivers the strongest airflow delivery from the compressor wheel for the ultimate in HP potential.


     The GTX2971R makes an excellent upgrade turbocharger especially for vehicles originally equipped with a T25 turbocharger from the factory.  Generally speaking, this turbocharger will bolt right up to the factory manifold just like the OEM turbo.  Of course because of its 550 HP+ airflow delivery, this is quite a bolt-on upgrade.  In most cases it will more than double the engines rated output.  As a stand-alone turbocharger for a purpose-built engine it offers spectacular responsiveness and very strong top-end airflow delivery.  Any engine with a pair of GTX2971R turbochargers will have to be built strong enough to withstand more than 1100 HP.  These turbos deliver some strong perfomance numbers for sure.

     This is the 11-blade billet aluminum compressor wheel equipped GTX2971R.  A rather large 4” anti-surge inlet compressor housing coaxes 77% aerodynamic efficiency from the 50mm compressor wheel.  Honeywell-Garrett uses computer-engineered aerodynamic profiling to take this compressor wheel size to another level and uses a dual ball-bearing supported turbine wheel for a 55 pound per hour airflow delivery level.  A perfect turbocharger for smaller engines that need a turbocharger with loads of airflow well above the 500 HP level with plenty of responsiveness and compact dimensions for tight engine bay installations.

Honeywell-Garrett GTX2967R

     When you couple a highly efficient 50mm billet compressor wheel to a rather large 57mm turbine wheel you end up with the insanely responsive GTX2967R turbocharger.  The ability to support nearly 500 HP doesn't hurt either.  This ball-bearing turbocharger should be nicknamed 'quicksilver' or something like that.  This is the PERFECT turbocharger for road-racing powerplants.  Very capable when used in twin-turbo setups with an output exceeding 900 HP with ease.  With the GTX2967R, 'lag' is not even an option.  Response is fast, and even faster.

     The GTX2967R is a rare combination of a turbine wheel that is generally found on much larger turbochargers, and a rather modestly sized compressor wheel which weighs almost nothing.  The result is instantaneous turbocharger acceleration.  It doesn’t take very much exhaust gas volume to light this turbocharger off either, as engines far smaller than 2.0 liters will enjoy extremely strong response with the GTX2976R.  It’s advanced aerodynamics are the reason for such fantastic performance.  Honeywell-Garrett put some work into this turbo to make it as responsive as it is.


     The foundation of the GTX2967R is a combination of a 50mm (inducer diameter) Gen-1 billet compressor wheel attached to a 57mm high-flow turbine wheel, which is supported by a pair of ball-bearings.  These are ceramic ball-bearings mind you, extremely tough and very durable in the high-heat environment of a turbocharger.  Honeywell-Garrett has essentially perfected their ball-bearing cartridges for performance turbochargers at this point.  The predictable performance and proven reliability of their ball-bearing turbochargers has been well documented all over the world.  Using a CNC-machined, billet compressor wheel milled from a solid billet of forged aerospace-grade aluminum alloy, Honeywell-Garrett has outfitted the GTX2967R well.   The blades are thinner than any cast compressor wheel could ever be because of the forged alloy composition of the metal.  Using a complex computer program to perform the machining operation, these blades are shaped with an aggressive profile to move massive amounts of airflow quickly and efficiently.  How efficiently, you ask?  Peak efficiency is a remarkable 79% with this compressor wheel, only a few of the Gen-2 compressor wheels offer higher levels of efficiency.  It has been said, ‘if it ain’t broke, dont fix it’.  No wonder this small compressor wheel can deliver enough airflow to support close to 500 HP.  The 57mm turbine wheel is identical to that of the 84-Trim GTX2971R turbocharger so you know it can spin up rather quickly and support high levels of gas-flow volume.  Spectacular performance should be a given with these specifications.


     An over-sized 3” inlet is cast into the compressor housing for greater airflow capacity.  The compressor inlet also features anti-surge porting that not only reduces the likelihood of compressor wheel damage, but actually expands the compressor wheel map efficiency.  The housing itself is a very compact TO4B profile with a large 2” outlet on the compressor discharge.  Ten years ago, it used to require a 58mm compressor wheel to deliver this level of airflow.  Turbocharger aerodynamics have come a very long way with this company.  


     Four exhaust housings give you some flexibility for getting the best fitment and performance from your GTX2967R.  There is a wastegated T25-flanged .64 A/R housing which allows easy fitment to most OEM turbo manifolds originally fitted with a Garrett T25 turbocharger.  This makes this turbocharger an easy choice as an upgrade for such vehicles.  For more custom fitted engine builds there are 3 V-band housing options that feature both an inlet and outlet v-band flange configuration.  These are available in sizes from the smallest volume .61 A/R, up to the largest housing of a 1.01 A/R volume ratio.  As far as tuning the responsiveness of the GTX2967R the .61 and .64 A/R housings will have the best gas velocity characteristics and result in the strongest boost response.  The 1.01 A/R housing will have the most gas-flow volume capacity and support the most (turbocharger) airflow and power.


     Consider this to be the best responding GTX turbocharger in this size category.  There are really no words to describe the immediacy with which the GTX2967R will spool-up.  This is a phenomenal road-course turbocharger.  Absolutely brutal on a twin-turbo smaller-displacement engine.  A 3.5 liter engine with a pair of GTX2967R turbos will respond like a naturally-aspirated big-block.  A 940 HP big-block that is.  Low-end and midrange boost delivery will produce insane levels of torque with either one or a pair of GTX2967R turbos pressurizing the intake.

Honeywell-Garrett GTX2867R

     With a 550 HP delivery, the GTX2867R ball-bearing turbocharger delivers huge amounts of airflow from its pint-sized package.  A 50mm billet compressor wheel takes center stage with this very responsive turbocharger for smaller engines.  It’s second generation aerodynamic profile is the reason this turbocharger can boast such incredible performance from its modest compressor wheel size.  Smaller displacement engines will absolutely shine with one of these bolted up.  Honestly if you have the internal fortitude, try a pair of GTX2867R turbos for 1100 HP worth of pin you to the seat NOW, fun.

     How exactly does this 50mm compressor wheel equipped GTX2867R move enough air to support 550 HP?  Honeywell-Garrett applied a heap of aerodynamic technology to the compressor section, that’s how.  This turbocharger has a fully updated billet compressor wheel and housing with some trick machining done on the housing to reach this level of performance.


     A ceramic ball bearing supports each end of the turbine shaft inside of the GTX2867R‘s CHRA.  Garrett pioneered this technology some years ago and has pretty much perfected it At this point.  The performance and durability of their ball-bearing turbochargers is know wherever turbochargers are used for performance engine builds.  This latest example of that technology is at the center of this turbochargers outstanding responsiveness and high-rpm capability.  You can really lean on these turbochargers with some pretty high boost pressures, well above the 2 BAR level.  To flow the amount of air this turbocharger can move at the rpms it can achieve, requires a very strong compressor wheel, to this end the GTX2867R has a second generation 8-blade billet wheel.  Honeywell-Garrett has fitted a CNC-machined, aluminum alloy wheel with adanced aerodynamic profiling that has a wide range of its peak efficiency flows rates.  This next-level compressor wheel design is why the GTX2867R can achieve such impressive airflow rates with a mere 50mm compressor wheel inlet diameter.  Driving this compressor wheel is a 54mm turbine wheel with a 69% efficiency rating which is as high as the majority of the best GTX turbine wheels can boast.  It obviously delivers enough rotational torque to get the compressor wheel up to the peak rpm levels fast.  The 500 HP+ rating of this turbocharger is proof positive to the turbine wheel’s effectiveness.  This combination of compressor and turbine wheels is very well suited to deliver high airflow volumes quickly.  


     As a complement to the compressor wheel Honeywell-Garrett has fitted a redesigned compressor housing to fully exploit its performance capabilities.  The large 3” diameter inlet has a ported shroud offering anti-surge properties to the housing.  The inlet has a few machining operations applied to improve the incoming airflow efficiency.  The inlet has a smooth bore on both the larger inlet cavity and the inner compressor inlet has been radiused towards the compressor wheel inlet.  A new casting process gives the exterior and interior passageways smoother surfaces for better airflow properties.  This housing also features a compact .60 A/R for very fast boost build-up from the compressor wheel.  A fully machined port has been added to the housing for a speed sensor allowing the option of monitoring turbocharger performance directly.  Now you can data-log the GTX2867R compressor wheel speed with accuracy.  The housing itself has a very small diameter which is key to the GTX2867R’s compact profile allowing placement in some small engine bays with room to spare.  


     There are 4 turbine housing choices available for the GTX2867R.  A pair of T25-flanged housings, and 2 V-band housings.  The T25 housings are for an internally-wastegated setup and are offered in .64 A/R and .86 A/R sizes.  The V-band housings are specially cast in a high-Nickel content Stainless Steel alloy.  This offers better durability with the high-temperature applications of highly-tuned turbocharged engines.  The housings are available in either a .57 A/R or .72 A/R.  Both of thes ehousings have a V-band flange on the inlet of the housing and a large V-band flange integral with the turbine discharge.  These flanges are precision-machined to tight tolerances for secure seal of the incoming gasses and the exhaust discharge.   All of these housings take full advantage of the turbine wheel thermodynamic flow rates and offer strong turbine acceleration and excellent turbocharger response.  The smaller .57 and .64 A/R housings will produce the fastest turbocharger response, while the .72 and .86 A/R housings will alloy the GTX2867R to achieve its top airflow potential.


     The turbine wheel and compressor wheel combination on the GTX2867R is so efficient that an engine of just 1.4 liters will generate enough exhaust energy for it to perform well.  Depending of the housing fitted to the exhaust side it has a wide output range of between just under 300 HP to 550 HP allowing many applications.  The internally wastegated housing options make the GTX2867R turbocharger a great choice for upgrading a factory turbocharged engine.  In most applications it will bolt right up to the factory manifold and deliver even better response and engine power will be impressively upgraded.  This is a great turbocharger for twin-turbocharger fitments, especially those with limited space for the turbochargers to be placed into.  With the potential of supporting a hefty 1100 HP, these are not ’small’ turbos as far as their performance goes, just their size.

Honeywell-Garrett GTX2860R

     The 475 HP GTX2860R proves that good things come in small packages.  The tiny external footprint of this turbocharger hides its huge airflow capapbility well.  The dual ball-bearing CHRA features an advanced Gen-2 billet compressor wheel, which is key to the outstanding airflow which the GTX2860R delivers with such immediacy, it borders on telepathic.  

     The GTX2860R turbo is a compact ball bearing unit that is ideal for smaller engines of 1.4 liters to around 2.5 liters displacement. It has a compact compressor housing with a ‘ported shroud’ 3” inlet and 2” discharge.  The .60 A/R housing assures quick air pressurization within the scroll and strong compressor response characteristics. The second Generation compressor wheel design extends the horsepower delivery of this turbocharger to nearly 500 HP!  This latest compressor housing also includes a speed sensor port machined into the inlet base for compressor wheel monitoring.  This is a great feature to use with these turbos to monitor the shaft rpms and keep them from over-speeding.

     The CHRA is a dual Ceramic ball-bearing architecture constructed around a durable 54mm Inconel alloy 76-trim turbine shaft.  Honeywell-Garrett has fitted a water-cooled bearing housing to keep the bearing cartridge running cool.  The compact bearing housing has 2 (water) ports for coolant circulation through the housing cavities.  This housing keeps the oil which lubricates the bearings from breaking down from the heat of the exhaust temperature radiating from the turbine housing.  It also reduces the occurrence of carbon deposits in the turbine housing area of the turbocharger.  The turbine shaft has the billet CNC-machined 60mm diameter compressor wheel attached to the opposite end of the turbine wheel.  The GTX2860R compressor wheel has a very small 46mm inducer and is essentially as light as a feather.  A mere breeze will get it spinning.  Perfectly responsive combination of turbine and compressor wheels that deliver boost pressure in less than an instant.  Precision balanced to spin at upwards of 180,000 rpms, this rotor group has a peak efficiency well over 70%.  

     Turbine housing options range from a choice of a .57 A/R or .72 A/R V-band inlet and outlet designs, or either a .64 A/R or .86 A/R housing choice with a T25 inlet flange and 5-bolt wastegated outlet.  These 4 options allow a few different ways to get the best performance from the GTX2860R.  These make great turbos for twin-turbo systems requiring nearly 1000 HP worth of airflow with ultra-fast response and compact turbocharger dimensions.  You can fit these small turbochargers in about the same space of a small battery, actually even smaller than that.  In single fitments the GTX2860R delivers in between 200 HP and 475 HP with insanely fast boost response.

     This may very well be the most responsive turbocharger ever created.  The G25-550 was engineered to have the best reponsive airflow deliver possible within its small dimensions.  Honeywell-Garrett started with a clean sheet of paper andcame up with this turbocharger.  Every single component is purpose made to the G-Series design parameters.  It delivers a heady 550 HP stream of airflow out of the compressor discharge from its tiny compressor wheel.  Simply incredible.  The nickname of ‘Mighty-Mouse‘ would be entirely appropriate for they G25-550.


     The dual ceramic ball-bearing cartridge at he center of the G25-550 features a sturdy 8mm turbine shaft diameter.  The bearing cages are Stainless Steel to handle the stress levels inside the cartridge.  On both ends of the bearing assembly there are 2 piston seals for tight oil control within the turbocharger CHRA.  At the compressor end, the backplate is an integral part of the bearing housing for the highest level of rigidity possible.  This singular housing/compressor backplate design also quarantees the tightest tolerances to be maintained in between the compressor wheel and the backplate cavity for the best aerodynamic efficiency.  The forged T-6 alloy billet compressor wheel is a brand-new 9-blade design.  It has the benefits of being both a low-mass and high- aerodynamic performance design.  Each blade is precision-machined on CNC machining centers for the ultimate in consistent blade thickness and profile.  With a peak efficiency of 80% you can see that Honeywell-Garrett has achieved great levels of airflow performance with this small compressor wheel.   Just let the numbers sink in for a minute , 550 HP from a 48mm compressor wheel inlet diameter.  The turbine wheel is just as advanced and capable.  Even though it is a fairly small 54mm in outer diameter and 49mm at the blade exit (exducer), it flows at higher levels than even a similarly sized GTX turbine wheel.  The blade profile features a 9-blade layout with plenty of spacing between the individual blades to allow exhaust gasses to flow through as they exit the wheel.  These blades and the entire wheel assembly have been precision-cast from a Mar-M ‘Superalloy’.  Without this alloy’s 1922 degree Fahrenheit temperature rating the wheel would not have its superior strength and high-heat durability.  This ‘Superalloy’ allows Honeywell-Garrett to make the individual blades very thin and reduce their mass significantly.  These combined elements of the turbine wheel design result in a 20% improvement in the flow capacity versus a comparable GTX turbine wheel.  The advanced specifications of the G25-550 CHRA are the secret behind its incredible performance and responsiveness.  


     Full of special features and with key areas being precision-machined, the compressor housing fitted to the G25-550 is a suitable complement to the CHRA.  At the opening of the compressor is a fully-machined anti-surge ported shroud inlet.  The ported shroud keeps damaging surge at bay and extends the efficiency of compressor wheel map.  At the base of the compressor housing inlet there is a precisely-machined speed sensor port which allows you the option of data-logging the speed of the rotor-group accurately to keep tabs on map efficiency and potential overspeeding rpm levels.  Additionally, there is a boost reference port machined into the housing scroll are close to the speed sensor port.  This is a perfect placement for a fitting to be inserted for either a boost gauge or wastegate actuator.  The entire compressor housing has been cast with an improved process that delivers a smoother exterior and more importantly, interior scroll passage surface.  A .70 A/R housing affords strong boost build-up flow rates from the billet compressor wheel to be delivered out of the 2” compressor discharge.  With all of these features being packed into a housing which is smaller than 8” in overall diameter, the G25-550 compressor housing delivers outstanding airflow levels and aerodynamic efficiency from a pint-sized package. 

     

     Turbine housing options include both a T25-flanged internally wastegated fitment and (4) V-band flanged housing choices.  The .49 A/R housing is perfect for making the G25-550 a factory turbocharged bolt-on fitment upgrade.  It also makes the very best spool-up possible with the highest turbine wheel velocities within the housing.  The .72 A/R and .92 A/R V-band housings deliver higher exhaust gas volume levels to the turbine wheel and thus the ability to support the full airflow capacity of the compressor wheel at the other end of the turbine shaft.  These V-band housings are available in both a wastegated and non-wastgated configuration.  To best cope with the extreme temperatures of the Mar-M turbine wheel rpm shaft speeds, these housings have been cast from a Stainless Steel alloy that is high in Nickel content, best suited for durability in this higher temperature environment.


     As Honeywell-Garrett has designed into the G25-550 specifications from the very beginning, there are really no competitors as far as turbine wheel acceleration rates.  Engines as small as 3.0 liters with a pair of G25-550 turbos have responsiveness like large displacement high-compression engines.  These G-Series turbos will have immediate response characteristics more like an electric motor.  Extremely direct in delivery of airflow output, even with the smallest engine displacements, and having throttle response being immediate and without any delay whatsoever.  The best part is the low-rpm and midrange torque delivery, even with a pair of G25-550 turbos with the larger .92 A/R housings on an 1100 HP tuned (small displacement) engine.  Traction and throttle control are the challenges with the new G25-550 turbochargers, not ‘lag’.

Honeywell-Garrett G25-550 

     The G25-550 from Honeywell-Garrett is a fresh design that delivers the very best responsiveness from a 48mm compressor wheel inlet size.  A highly-efficient billet compressor wheel and turbine wheel combination supported by 2 ball-bearings delivers the very performance and reliability.  Packed with various key aerodynamic features, the G25-550 can easily support an incredible 550 HP from a very small engine of 1.4 liters.  Spectacular responsiveness is this turbo's forte.  Its tiny footprint means you can place this turbocharger almost anywhere you want, with room to spare in most cases.

     There is quite a bit of expert engineering invested by Honeywell-Garrett in making the G-Series turbochargers as compact and capable as they are.  The largest specification G25-660 can support an incredible 660 HP from an engine of only 1.4 liters of displacement.  To say this is an efficient design is like call the 'Mona Lisa' a nice painting.  The compressor wheel and turbine wheel designs are even more well-developed than the  spectacular GTX components.  This tiny turbocharger really is 'as good as it gets'.  You won't find a smaller turbocharger that can deliver the level of aiflow and responsiveness as this.

     At the core of the brand new G25-660 is a dual ceramic ball-bearing cartridge.  It has a Stainless Steel bearing cage for the the best durability possible.  On the hot side of the CHRA is a newly-designed turbine wheel made from Mar-M, an aerospace alloy of extremely high-temperature stable properties.  It can withstand a constant 1050 degree Celsius exhaust stream.  This advanced 84-trim turbine wheel profile delivers outstanding gas turbine dynamic flow rates which even exceed that of the GTX turbine wheel profiles.  Using Mar-M as the blade material has allowed for a profile which is very thin, not just at the outer edges, but closer towards the shaft centerline as well, for a significant reduction in mass and overall inertia.  This aspect is key to the G-Series turbocharger turbine acceleration being so very fast.  The blade profile of course, supports higher exhaust gas flow rates through the wheel, having a distinctively swept trailing edge and large spacing between each blade to allow gas to exit past without restriction.  Countless hours have been invested by the aerodynamicists at Honeywell-Garrett on this turbine wheel design with good reason, the G25-550 and 660 turbos owe their incredible performance more to it than even the compressor wheel specifications.  Speaking of which, the 9-blade compressor wheel is clearly worthy of its own praise.  It features a forged aluminum alloy billet wheel design that is very low in mass, yet it can exibibit next-level airflow capability because of its aerodynamic shaping and profile.  These CNC-machined compressor wheels offer very tight dimensional tolerances in the .001“ range which is key to efficiency in high-rpm turbochargers.  The forged, billet aluminum material is necessary at this level of turbocharger design to achieve such performance and offer the needed durability that is expected.  Being able to move about 60 pounds of air each minute with a rather small 54mm compressor wheel inlet diameter is a noteworthy feat, so the level of development invested by Honeywell-Garrett has returned excellent results.  


     A feature-packed compressor housing surrounds the billet wheel and turns the airflow from the wheel into a mighty stream of pressurized air for your engine to digest.  The inlet has been machined with precision and it has an anti-surge channel surrounding the compressor wheel.  On the discharge scroll a .70 A/R ratio makes the best of the airflow for quick boost-delivery from the turbocharger compressor wheel flow abilities.  This new casting has a smoother finish compared to housings of the past and is a key element in maintaining the G-Series flow efficiency levels.  There is a pre-machined boost reference port and also a port for an optional speed sensor in the compressor housing.  An o-ring is fitted in between the compressor housing and the backplate surface to keep boost pressure from having the opportunity to escape.  The G25-660 has a full-featured compressor housing there is no doubt.  A great match to the compressor wheel itself that is covers.


     Several options exist from Honeywell-Garrett for the turbine housing you can fit to the G25-660.  To guarantee the best durability in the high-temperature applications of the G25-660 fitments, a high-Nickel content Stainless Steel alloy is used to cast these housings.  There is a .49 A/R T25-flange housing for an internally wastegated configuration.  Additionally there are a quartet of housings all of which have a V-band flange on the inlet and outlet with sizes of a  .72 A/R and a .92 A/R.   These V-band housings can be had with or without a wastegate port.  The .49 A/R and .72 A/R housings will produce the strongest boost response characteristics possible, and the .92 A/R housings deliver the best airflow and HP potential.

Honeywell-Garrett G25-660

     These special billet compressor wheels are aerodynamic works-of-art.  Sculpted from solid T-6 alloy billet blocks of aluminum by CNC-machining centers, to the lightweight shapes you see here.  The bladeforms are very thin to keep the weight as low as possible.  Each profile has undergone extensive computational fluid dynamic analysis to be as aerodynamically efficient as Homeywell-Garrett can make within the small dimensions of the G-Series footprint. 

     The ultra-compact bearing housing Honeywell-Garrett has specially cast for the G-Series turbochargers is so small, that the v-band clamps used to secure it to its turbine housing is just about as thick as the width between the compressor flange and the turbine flange.  Packed into this small space is a pair of ceramic ball-bearings with high-strength Stainless-Steel cages and an intricate channel for coolant to flow through for bearing temperature regulation.  The Mar-M turbine shaft has a great environment to live in within this housing for certain.  Four ports for fittings allow a few different configurations for coolant line connections to be made as well.  What a CHRA.

     Most of the housing options available for the G-Series turbochargers featurea a full V-band configuration.  This assures optimal high-gas flow capability and gasket-free connections.  These housings are cast in a Stainless Steel alloy that has a high Nickel content making them very durable in high thermal-load environments.  They can take the heat.  V-band clamp flanges are precision-machined for a flat, and leak-free connection to the manifold and downpipe.

    Honeywell-Garrett has fitted the G-Series turbochargers with these special 'Super alloy' forged Mar-M turbine wheels.  This material has a continuous temperature rating of 1050 degrees Celsius or 1922 degrees fahrenheit.  The blade shape, curvature, thickness, and base profile has been engineered to perform at the rpm range of the G-Series turbochargers.  These wheel profiles exhibit about 20% better flow than a comparable 54mm GTX turbine wheel, which is quite impressive.  They are absolutely essential to the performance of the G-Series turbochargers.

Honeywell-Garrett GTW3884R

     Honeywell-Garrett combines a  74mm turbine wheel and you choice of a 62mm, 64mm, or a 67mm billet compressor wheel for supporting in between 450 HP and 950 HP.  These T4 performance turbochargers are available in a journal bearing or dual ball-bearing CHRA configuration.  The GTW3884R turbos also include a billet aluminum backplate and water-cooled bearing housing.  The large inlet compressor housing has anti-surge porting for efficiency and compressor wheel protection from surge damage.

     The GTW3884R is a straitforward 450 to 950 HP capable turbocharger that is tough enough to provide the same level of performance year after year.  With a billet compressor wheel being housed inside a high-flow anti-surge compressor housing, it goes about delivering large amounts of airflow with ease.  The optional ball-bearing shaft support gives increased durability and response while the journal-bearing CHRA is simple to maintain and service down the road if ever needed.


     The journal-bearing CHRA is a well-developed and proven configuration based on a T4 turbine shaft and an upgraded billet compressor wheel being supported by a pair of tough bronze bushings and a heavy-duty thrust plate assembly.  The 74mm P-trim turbine wheel is made of an Inconel ‘Super-alloy’ and has been proven to be able to support over 1000 HP compressor loads.  The forged aluminum alloy compressor wheel delivers lower mass, higher strength, and more efficient aerodynamic performance than a cast aluminum compressor wheel could.  These CNC-machined billet wheels are essential to the strong response and expanded performance delivered by the GTW turbocharger lineup.  For the GTW3884R turbocharger Honeywell-Garrett has fitted a 10-blade wheel with thin blades aggressively swept for higher airflow at elevated shaft speeds.  The higher tensile strength of the forged aluminum blade material allows for a very trim compressor wheel design with minimal mass at the blade base and around the shaft itself.  This allows for very low inertia and greatly contributes to turbo response.  The GTW3884R has 3 Compressor wheel diameter options from the smallest of 62mm up to the largest 67mm.  The 62mm turbocharger can efficiently deliver in between 400 and 650 HP depending on the turbine housing selected.  The 64mm compressor will deliver enough airflow to support about 500 to 775 HP.  Selecting the 67mm billet compressor wheel option allows a range of between 700 HP and 950 HP to be generated.


     A large opening of 4” in diameter and a .70 A/R announce the healthy amount of airflow expected to be moved through this compressor housing.  Anti-surge porting of the inlet increases compressor map efficiency and protects the wheel fro surge effects should they be encountered.  The large 2.5” outlet passage delivers high-volumes of pressurized air from the compressor wheel with ease.  This housing is all about simple airflow efficiency and volume.


     Turbine housings for the GTW3884R are sized to allow the turbine wheel unrestricted gas flow through its blades for the best power levels to be supported from the compressor wheel selection in the housing on the other end of the shaft.  These housings are fitted with a T4 flange on the inlet and a V-band flange on the outlet.  A .96 A/R housing and larger 1.14 A/R housing are available to fit the 76-trim turbine wheel perfectly.  The .96 A/R housing will support the best response and fastest boost rise on the GTW3884R, while the 1.14 A/R housing flows more exhaust volume and allows the compressor wheels to reach their optimal airflow rates.  


     Since a single GTW3884R turbocharger can deliver such strong performance there are countless applications.  From a small import engine to a large displacement V8, the GTW3884R can be configured to fit the build quite nicely.  A pair of 67mm GTW3884R turbos can generated enough airflow to support a rather strong 1900 HP from an engine.  Pretty serious turbochargers these are.  The modest configuration allows a lower price point as well so that a lower budget competitor can still make great power and get many years of reliable service out of this choice of turbocharger.

Honeywell-Garrett GTW3684R

     The GTW3684R turbocharger offers a simple 750 HP turbocharger solution from a combination of a 71mm turbine wheel and an efficient 62mm billet compressor wheel.  This T4 turbocharger can be fitted to any engine from around 2.0 liters up to almost 6.0 liters of displacement.  This mid frame sized turbocharger has a large compressor inlet with a ported shroud, a lightweight billet aluminum backing plate , and a water-cooled bearing housing.

     The GTW3684R delivers a serious level of airflow rom its 62mm compressor wheel size.  This is a very easy solution for a 750 HP requirement from a single turbocharger and a top choice as well for a 1500 HP twin-turbo build.  Expect very strong power delivery even with a modest engine displacement of only 2.0 liters.  The compressor range of efficiency is quite wide with the GTW3684R turbocharger delivering over 65% efficiency while providing enough airflow for 700 HP.  This is a midrange-delivery monster of a turbo that will put a smile on your face every time you give it even half throttle.  


     Honeywell-Garrett combines a CNC-machined 10-blade billet aluminum compressor wheel with a 62mm inlet diameter with a 71mm turbine wheel to come up with this very fast responding mid-frame turbocharger.  The CHRA has features like a water-jacketed bearing housing, durable dual ceramic ball-bearing cartridge, and lightweight billet aluminum compressor backplate.  The optional journal bearings even have a heavy-duty thrust plate assembly.  This CHRA is built for the long haul.  The ball-bearing cartridge gives the best performance with the fastest response time and highest boost pressure durability.  This technology comes from the pioneers of performance ball-bearing turbochargers for the aftermarket and OEM manufacturers.  It just plain works.  The turbine wheel is an Inconel alloy high-efficiency design that does better than 70% efficiency making it as good as some of the best GTX turbine wheel Honeywell-Garrett has designed.  It has lower mass than the larger GTW3885R turbine wheel so it can accelerate even faster to get the compressor wheel up to peak airflow speeds.  With a water-cooled bearing housing the GTW3684R will keep its performance at the same level even when the outside temperatures or the competition heats up.  


     Matched up to the 62mm compressor wheel is a large inlet, ported shroud housing.  This 4” inlet housing was designed to flow air at large volumes and with the anti-surge slots and porting with higher compressor wheel efficiency.  The .70 A/R housing allows high-volumes of air to exit the compressor wheel into the discharge at strong velocities for rapid boost buildup before being expelled from the turbocharger itself.  The 2.5” exit is large enough to support the 750 HP worth of airflow the GTW3684R can deliver with ease.  Nothin fancy, just proven compressor housing aerodynamics that deliver strong airflow delivery throughout a broad operating range.


     A trio of turbine housing options allows a wide range of turbo response and power delivery tuning.  The smallest housing offers a .70 A/R and gives you the absolute fiercest boost response from the GTW3684R.  On the other end of the options sits a 1.15 A/R housing that will allow the GTW3684R to fully achieve its peak 750 HP level of airflow potential.  All of these housings have a very efficient V-band outlet cast into the turbine housing exit for both a secure downpipe connection and a low-turbulence gas pathway out of the turbine wheel blades.


     The GTW3684R has very strong response characteristics that really bring out the best midrange an engine has to offer.  With a top-end deliver of 750 HP this turbocharger is no ‘lightweight’.  It only needs a modestly sized engine to make it perform well, anything 2.0 liters and larger is a perfect match.  This is an excellent choice for a road-course tuned engine that has to deliver strong midrange power for exiting out of the corners.

     This GTW3476R delivers a stout 700HP by using a highly-efficient 58mm billet compressor wheel and a fast-spooling  65mm turbine wheel combination.  This T3/T4 hybrid configuration offers the best match of a fast-response T3 turbine wheel and the high-volume airflow of a T4 compressor wheel.  The water-coolec bearing housing, billet aluminum backing plate, and ported shroud inlet make this a feature-packed turbocharger with plenty of performance for an engine in between 2.0 liters and 5.0 liters of displacement.  

     The GTW3476R is a potent hybrid turbocharger with fast boost response and a highly efficient airflow range.  Honeywell-Garrett has created a durable T4/T3 hybrid that takes full advantage of its 58mm billet compressor wheel.  The ported shroud inlet, water-cooled bearing housing, lightweight compressor backing plate, and large compressor housing opening are all very useful features that combine to add better performance, durability and value to this turbocharger.


     At the core of the GTW3476R is a high-flow T3 turbine wheel that is key to fast turbo boost response and driving the compressor wheel well at high airflow volumes.  The compressor wheel on this CHRA is a very efficient 58mm 10-blade forged aluminum design.  Honeywell-Garrett has CNC-machined this billet wheel to be low in mass, strong, and capable of high-airflow volume movement.  With a 77% peak compressor efficiency, this wheel wastes little energy in turning the incoming air column into a pressurized stream.  A pair of ceramic ball-bearings support the turbine shaft and deal with the thrust loads imposed by the compressor wheel. This proven technology assures durable performance that remains as potent as the first time it was spooled up for years to come.  A fully water-jacketed bearing housing keeps the bearing cartridge from getting to hot while the turbocharger is in operation.  Even the journal-bearing option includes a heavy-duty thrust plate and washers to cope with the loads the GTW3476R will endure.  The 65mm turbine wheel has the advantage of being low in mass and easy for the exhaust gas stream to accelerate and drive the compressor wheel on the other end.  It features a 69% gas-flow efficiency and is made from an Inconel alloy for superior high-heat durability.


     Surrounding the billet compressor wheel is a well-appointed compressor housing that has the right features to support efficient airflow and strong boost build-up.  The compressor inlet has a large 4” opening that has anti-surge porting cast into it.  This not only protects the billet wheel in the rare event of compressor surge, but actually extends the compressor map efficiency farther.  The housing itself has been cast with a .70 A/R discharge to assure fast boost production from the billet compressor wheel spinning away inside.  It has a high-flow 2.5” outlet to support large volumes of pressurized air with little turbulence or restriction.


     Three turbine housings can be fitted to perfectly tailor the response curve to your engine’s needs.  These housings have a T3 flange on the inlet and a 4-bolt flange on the turbine outlet for connection to a downpipe.  The housing sizes Honeywell-Garrett has fitted to this GTW3476R 76-trim turbine wheel are a .48 A/R for the quickest boost response possible, a .63 A/R which has both good volume and gas velocity characteristics, and the .82 A/R which allows the GTW3476R to achieve the maximum airflow possible for top-end power.


     Engines of around 2.0 liters, and of course larger, will perform very well with a GTW3476R bolted onto the exhaust manifold.  With an output range of 450 to 700 HP this turbocharger has a wide scope of applications.  It spools up very fast even with the larger .82 A/R turbine housing selection because of its lightweight billet compressor wheel.  A pair of GTW3476R turbos will reliably deliver 900 HP up to 1400 HP worth of airflow with excellent low-rpm and midrange response.
