Garrett GTX3071R Gen II Turbo
Boost Power With the Garrett GTX3071R Gen II Turbo
Garrett's Gen II GTX3071R dual ball bearing turbo has the company's ultra high flow compressor wheel featuring Garrett 8-Blade technology. Compressor housing is GTX30 style with 4″ inlet and 2″ outlet but has built-in anti-surge machining. Improved ported shroud design for surge resistance. This turbo is sold as a complete assembly with supercore and turbine housing. There's a new fully-machined speed sensor port included on all Gen II GTX turbos—a speed sensor is highly recommended.
While the GTX3071R is a fantastic turbo for multiple applications, the G25-660 is an option that somewhat supersedes it and is the most powerful small-frame turbo on the market. That said, the GTX3071R Gen II Turbo has proven itself to be a truly good turbocharger, boosting power considerably and reliably.Â

About Garrett GTX Series Turbochargers
Garrett GTX Series turbochargers are designed specifically for hard-core enthusiasts who want optimal performance. The forged fully-machined billet aluminum compressor wheels feature next-generation aerodynamics that provides a larger horsepower range and maximize boost response.
Ported shroud compressor housings increase surge resistance and provide reliable, continuous power throughout the power band. A dual ceramic ball bearing cartridge prolongs the lifespan and improves shaft balance. The watercooled CHRA keeps housing temperatures to a minimum. The turbine wheel is constructed from Inconel, a Super Alloy that maintains strength during prolonged exposure to high exhaust gas temperatures.
