The EFR 6758 Super Core is the complete rotating assembly and compressor stage of an EFR 6758 turbo on the B1 frame: a 67mm forged milled compressor wheel (54mm inducer) and a 58mm Gamma-Ti turbine wheel on dual ceramic ball bearings in an aluminum bearing housing, with the compressor cover, compressor recirculation valve (CRV) and boost control solenoid valve (BCSV) assembled. The turbine housing, clamp plate hardware, wastegate and actuator are not included, so it is the part to buy when keeping an existing EFR turbine housing or choosing a housing separately. Aluminum bearing housings require water cooling.
