Product description
S475 Turbo Replacement for 171702. This turbo is popular for Detroit Diesel replacement turbos and for installation for compound turbos with goal of 650-750HP. Compressor wheel is 74.5mm inducer and has the 96/88 turbine wheel. It comes standard with the 1.32AR T6 turbine housing. For compound applications with HX35 or HE351CW turbos we recommend upgrading to the faster spooling 1.15 T6 a/r housing to move the usable powerband lower in the RPM range for even better EGT control.
