With 22 years of documented research and development in the forced induction field, AMS Performance has proven itself as the powerhouse in the automotive aftermarket. Our award winning performance systems are what all others are measured by.

Honeywell Garrett, is excited to announce the release of our Gen II GTX Series turbochargers. The GTX3071R, GTX3076R, GTX3576R, as well as the GTX3582R are included in the release. The GTX Gen II line received a major compressor wheel aero update that gives it the ability to produce up to 20% more horsepower than the previous version. You can also get these turbochargers in a Reverse Rotation configuration!



GTX Gen II compressor wheels were designed using proprietary Honeywell computer simulation technology focusing on CFD analysis to optimize the wheel design to reach maximum efficiency and mass flow for each turbocharger. Each GTX Gen II turbocharger has the ability to create more air mass flow, offering enthusiasts a wider range of power output when tuning the vehicle. The 8mm dual ceramic ball bearing cartridge provides optimal turbo response and reliability through its reduction in shaft motion.

The Gen II GTX Series Turbochargers feature a fully-machined compressor inlet, fully-machined compressor outlet, and fully-machined ported shroud.

We also added a brand new compressor housing featuring a high-flowing design matched perfectly for the new compressor wheel upgrade. Gen II compressor housings are not interchangeable with Gen I compressor wheels; however, all Gen II turbochargers are outline interchangeable with the equivalent GT and GTX Gen I products making a turbo swap easy to perform using all existing piping.

The new compressor housings are equipped with a fully machined speed sensor port that accepts the Honeywell Garrett speed sensor (Sold separately). This feature allows tuners to understand existing operating conditions, which is important when fine tuning a turbocharger to its most efficient operating conditions. The speed sensor port comes plugged from the factory and can be removed using a 5mm allen key when ready to install a speed sensor kit.

All Gen II GTX series turbochargers are compatible with existing GT and GTX turbine housings kits. Gen II turbochargers are only offered through Honeywell Garrett authorized distribution centers.

Available in four sizes: the GTX3071R, GTX3076R, GTX3576R, and GTX3582R Reverse Rotation turbochargers are ideal for twin turbo, V engine applications and for fabricators that want perfect symmetry to be displayed in the engine compartment. The Reverse Rotation turbos can also be used in single turbo applications where packaging is an issue. The compressor wheel spins in a counter-clockwise rotation while the compressor outlet exits air to the left, making its components non-interchangeable with Gen 1 or Gen II standard rotation products.

Featuring the new GTX Series Gen II compressor wheel designed using proprietary Honeywell computer simulation technology. Reverse Rotation turbochargers should be paired with a Gen II Standard Rotation counterpart and are not recommended to be matched with a Gen I turbocharger because the higher horsepower rating could lead to engine or other mechanical failure.

Reverse Rotation turbochargers have specifically designed turbine housings ranging from 0.61, 0.83, and 1.01 A/R and are not compatible with standard rotation housings.


WARNING: Maximum allowable turbocharger speed is 145krpm. The use of this product above max turbocharger speed is at the owner’s risk, and can result in damage and premature failure. To protect the turbocharger from overspeed when operating, a speed sensor can be installed into the compressor housing to monitor shaft speed. Sensors sold separately. (click here for details)

Performance results of this product are highly dependent upon your vehicle’s modifications and tuning/calibration. The horsepower numbers represented above are calculated based strictly on choke flow of the compressor map (total turbo capability), which represents the potential flywheel horsepower.
