Rated up to 1,250 horsepower on 2.0L to 6.0L engines, the GRT934173-5008S delivers 23% more compressor flow than the G40-900 via enhanced pressure ratio capability and next-generation compressor aerodynamics. The V-Band outlet on GRT934173-5008S mates cleanly to aluminum intercooler piping without the need for hose connections, making it a preferred choice for purpose-built race platforms and clean engine bay builds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGRT934173-5008S G-XRace GXR38-64 supercore with 64mm compressor inducer and V-Band compressor outlet\u003c\/li\u003e\n\u003cli\u003eXBoost Technology compressor aero delivers 23% greater flow over the G40-900 for extreme top-end horsepower\u003c\/li\u003e\n\u003cli\u003eDual ceramic ball bearing CHRA for rapid spool-up, reduced friction, and long service intervals\u003c\/li\u003e\n\u003cli\u003eInconel turbine wheel handles extreme exhaust heat in built high-boost race applications\u003c\/li\u003e\n\u003cli\u003eV-Band compressor outlet for rigid, reliable charge piping connections in professional builds\u003c\/li\u003e\n\u003cli\u003eLightweight aluminum backplate reduces rotating assembly inertia for quicker response\u003c\/li\u003e\n\u003cli\u003eMachined speed sensor port for optional turbo speed monitoring via Garrett G-Smart sensor kit\u003c\/li\u003e\n\u003cli\u003eCompatible with G-Series and G-XRace turbine housing kits in T4 divided or V-Band inlet configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eGRT934173-5008S \/ 934173-5008S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eG-XRace GXR38-64\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompressor Inducer\u003c\/td\u003e\n\u003ctd\u003e64mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompressor Exducer\u003c\/td\u003e\n\u003ctd\u003e88mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompressor Housing Outlet\u003c\/td\u003e\n\u003ctd\u003eV-Band\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTurbine Inducer\u003c\/td\u003e\n\u003ctd\u003e73mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTurbine Exducer\u003c\/td\u003e\n\u003ctd\u003e66mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHorsepower Rating\u003c\/td\u003e\n\u003ctd\u003e500 to 1,250 HP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEngine Displacement\u003c\/td\u003e\n\u003ctd\u003e2.0L to 6.0L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTurbo Reference\u003c\/td\u003e\n\u003ctd\u003e6470\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Speed\u003c\/td\u003e\n\u003ctd\u003e125,000 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBearing System\u003c\/td\u003e\n\u003ctd\u003eDual ceramic ball bearing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTurbine Wheel Material\u003c\/td\u003e\n\u003ctd\u003eInconel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompressor Wheel\u003c\/td\u003e\n\u003ctd\u003eForged billet aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003eVerify with Garrett distributor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eWhat’s Included\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 x GRT934173-5008S G-XRace GXR38-64 Supercore Assembly with V-Band compressor outlet\u003c\/li\u003e\n\u003cli\u003eGasket kit\u003c\/li\u003e\n\u003cli\u003eWater fittings (AN6 nipples for coolant connections)\u003c\/li\u003e\n\u003cli\u003eNote: Turbine housing sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eAbout Garrett Motion\u003c\/h4\u003e\u003cp\u003eGarrett Motion has led turbocharger innovation for over six decades, developing the G-XRace platform specifically for motorsport applications demanding maximum airflow, reliability, and compressor efficiency.

It provides the rotating assembly and compressor housing and requires a compatible turbine housing kit to complete the turbocharger.\u003c\/p\u003e\u003cstrong\u003eWhat is the difference between GRT934173-5008S and GRT934173-5009S?\u003c\/strong\u003e\u003cp\u003eBoth are GXR38-64 supercores with identical core specifications. The GRT934173-5008S uses a V-Band compressor outlet for rigid pipe connections, while GRT934173-5009S uses a CH (clamped hose) outlet for flexible piping. Choose V-Band for rigid aluminum charge piping or CH for silicone hose connections.\u003c\/p\u003e\u003cstrong\u003eWhat turbine housings mate with the GRT934173-5008S?\u003c\/strong\u003e\u003cp\u003eThe GRT934173-5008S is compatible with Garrett G-Series and G-XRace turbine housing kits in 0.85, 0.95, and 1.06 A\/R with T4 divided or V-Band inlet options, sold separately under part numbers 757707-0037 through 757707-0044.\u003c\/p\u003e\u003cstrong\u003eDoes this supercore require an external wastegate?\u003c\/strong\u003e\u003cp\u003eYes. The GXR38-64 platform uses external wastegates only. An external wastegate appropriate for your boost target must be sourced separately and is not included with the GRT934173-5008S.\u003c\/p\u003e\u003cstrong\u003eWhat engines is the GRT934173-5008S compatible with?\u003c\/strong\u003e\u003cp\u003eThe GXR38-64 is a universal turbocharger supercore designed for 2.0L to 6.0L engines.
