Garrett offers gasoline-powered turbochargers called wastegate turbos. The turbos are set up in a twin-turbo configuration. Garrett also offers a diesel engine version of wastegate turbos and VNTs. The R34 GT-R turbos retained the ceramic exhaust turbine wheel. Ford offered a limited run of approximately 150 "Capri turbos" with turbocharged 2.8 engines. MHI and T-4 turbos were both used as power for these engines. The Noble M12 GTO-3R is equipped with Garrett T25 twin turbos. These changes led to increased horsepower and torque vs. the previous 1G turbos. The R34 turbos received a ball bearing core. Rookie twin Turbos, Paul and Gary Gait, set new standards in most offensive categories. Through the morning the unfortunate Bugatti needed all four of its turbos replaced. This was the last of the air-cooled 911 Turbos. A total of 3,660 964 Turbos were built. Despite this, CA20DET turbos have been built. A total of 436 ERA Mini Turbos were produced.
