About Garrett GTX Series Turbochargers
Garrett GTX Series turbochargers are designed specifically for the hard-core enthusiast who wants optimal performance. The forged fully-machined billet aluminum compressor wheels feature next generation aerodynamics that provide 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 water cooled 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.
Turbine kits are offered in open volute and twin scroll, and a variety of A/R and flange configurations. GTX Series turbochargers are used by today’s top motorsports teams and are ready to boost you to the podium or wherever your destination may be.
