The Garrett G-XRace GXR38-64 Super Core is the balanced rotating assembly at the heart of Garrett's race-oriented G-XRace turbocharger, built around a 64 mm forged aluminum compressor wheel on a ball-bearing center cartridge. Supplied as a super core, it includes the center housing, compressor wheel and compressor cover but no turbine housing, so a separate G38/GXR38 turbine housing kit sets the exhaust A/R. This version uses a hose compressor cover outlet for a silicone-coupler connection, and a machined sensor port supports turbo speed monitoring.
