Garrett GT30R - Dual Ball Bearing Garrett GT30R Turbo assembly with T3 style housing with T3 inlet flange w/ 4 bolt style exit. T04E style compressor housing with 2.75 - 3.00 inlet and 2.00" outlet. Very Good response turbo for 4 Cyl applications. This turbo has a flow capacity of about 500HP. This turbo would be the same as HKS GT3037. The GT30R turbine housings with 4 bolt exit are made out of ductile Ni-Resist iron (has a nickel content of about 38%). This material is much better at withstanding high exhaust gas temperatures than regular cast iron. The turbine wheel is inconnel 713 and is good for up to 1700 degrees farenheit. The wheel can sustain longer operation at higher temperature but not for long periods of time. You'll make a hell of a lot more power with this turbo than most turbos comparable!!!
