The T4 divided twin-scroll inlet on GRT757707-0043 preserves exhaust pulse energy from the manifold to improve low and mid-RPM turbo response, while the V-Band turbine outlet simplifies downpipe connections in custom fabricated exhaust systems. The 0.95 A\/R housing is the most versatile selection for G38 builds spanning 2.5L to 5.5L applications where both response and top-end flow capability are valued equally.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGRT757707-0043 turbine housing for G38-1000 and GXR38-64 supercores with T4 divided inlet and V-Band outlet\u003c\/li\u003e\n\u003cli\u003e0.95 A\/R ratio balances spool response and peak exhaust flow for broad RPM range power delivery\u003c\/li\u003e\n\u003cli\u003eT4 divided twin-scroll inlet for pulse energy retention and improved low-RPM spool characteristics\u003c\/li\u003e\n\u003cli\u003eV-Band turbine outlet for straightforward downpipe or midpipe connection\u003c\/li\u003e\n\u003cli\u003eStainless steel housing for sustained thermal durability in race and high-boost street applications\u003c\/li\u003e\n\u003cli\u003eExternal wastegate design for precise boost pressure management\u003c\/li\u003e\n\u003cli\u003eIncludes gasket kit, V-Band clamp, and mounting hardware\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\u003eGRT757707-0043 \/ 757707-0043\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Supercores\u003c\/td\u003e\n\u003ctd\u003eG38-1000 (938272-5003S), GXR38-64 (934173-5008S, 934173-5009S)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTurbine Inlet\u003c\/td\u003e\n\u003ctd\u003eT4 Divided (twin-scroll)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTurbine Outlet\u003c\/td\u003e\n\u003ctd\u003eV-Band\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eA\/R Ratio\u003c\/td\u003e\n\u003ctd\u003e0.95\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWastegate Type\u003c\/td\u003e\n\u003ctd\u003eExternal only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHousing Material\u003c\/td\u003e\n\u003ctd\u003eStainless steel\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 GRT757707-0043 G38\/GXR38 Turbine Housing Kit\u003c\/li\u003e\n\u003cli\u003eGasket kit\u003c\/li\u003e\n\u003cli\u003eV-Band clamp for turbine outlet\u003c\/li\u003e\n\u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003cli\u003eNote: Supercore sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eAbout Garrett Motion\u003c\/h4\u003e\u003cp\u003eGarrett Motion provides the complete G38 turbine housing family across three A\/R ratios and two inlet configurations to precisely match the housing to the engine, power target, and exhaust manifold design. The GRT757707-0043 represents the most commonly specified G38 housing for builds targeting a wide RPM power band.\u003c\/p\u003e\u003ch4\u003eFAQ\u003c\/h4\u003e\u003cstrong\u003eWhat is the GRT757707-0043?\u003c\/strong\u003e\u003cp\u003eThe GRT757707-0043 is a Garrett G38\/GXR38 stainless steel turbine housing with T4 divided inlet, V-Band outlet, and 0.95 A\/R ratio. It is compatible with the G38-1000 and GXR38-64 supercores and sold as a standalone kit requiring a separate supercore purchase to complete the turbocharger.\u003c\/p\u003e\u003cstrong\u003eHow does 0.95 A\/R compare to 0.85 and 1.06 for the G38?\u003c\/strong\u003e\u003cp\u003eThe 0.95 A\/R on GRT757707-0043 sits between the quickest-spool 0.85 A\/R (GRT757707-0042) and the highest-flow 1.06 A\/R (GRT757707-0044). It is the most balanced choice for builds spanning 3.0L to 5.0L engines where both spool and top-end output matter, and is typically the most popular selection for dual-purpose street and track builds.\u003c\/p\u003e\u003cstrong\u003eWhat displacement engines work best with GRT757707-0043?\u003c\/strong\u003e\u003cp\u003eThe 0.95 A\/R housing performs well across 2.5L to 5.5L displacements. It is particularly well matched to 4-cylinder 2.5L to 3.5L builds where moderate response with strong peak flow is desired, and to 6-cylinder applications in the 400 to 800 horsepower range.\u003c\/p\u003e\u003cstrong\u003eDoes GRT757707-0043 require an external wastegate?\u003c\/strong\u003e\u003cp\u003eYes. All G38 turbine housing kits are external wastegate only. An external wastegate appropriate for your boost level must be sourced separately.\u003c\/p\u003e\u003cstrong\u003eIs the T4 divided inlet the same bolt pattern as a standard T4 flange?\u003c\/strong\u003e\u003cp\u003eThe T4 divided inlet uses the standard T4 bolt pattern with a divided (twin-scroll) internal divider. The manifold must also be a divided T4 design with internal scroll separation to benefit from the twin-scroll pulse energy. A standard undivided T4 manifold can physically bolt up but will not provide twin-scroll benefit.\u003c\/p\u003e\u003cstrong\u003eAre G38 housings cross-compatible with G40 or G42 supercores?\u003c\/strong\u003e\u003cp\u003eNo. The G38 turbine housing family is frame-specific and cannot be used on G40, G42, or other Garrett frame supercores. Confirm the supercore part number is a G38 or GXR38 before purchasing GRT757707-0043.\u003c\/p\u003e\u003cstrong\u003eWhat is included in the kit?\u003c\/strong\u003e\u003cp\u003eGRT757707-0043 includes the turbine housing, gasket kit, V-Band clamp for the turbine outlet, and mounting hardware. Weld flanges for the downpipe are not included.\u003c\/p\u003e\u003cstrong\u003eDoes this housing include wastegate mounting?\u003c\/strong\u003e\u003cp\u003eThe GRT757707-0043 housing includes a dump port for the external wastegate connection. The wastegate itself must be sourced separately and is not included.\u003c\/p\u003e\u003ch4\u003eInstallation Overview\u003c\/h4\u003e\u003col\u003e\n\u003cli\u003eConfirm the G38 or GXR38 supercore is properly assembled with oil and coolant fittings in place\u003c\/li\u003e\n\u003cli\u003eAlign T4 divided inlet to the matching divided T4 exhaust manifold flange and bolt using supplied hardware\u003c\/li\u003e\n\u003cli\u003eTorque housing bolts to Garrett’s specified value to prevent warping or leaks under heat cycling\u003c\/li\u003e\n\u003cli\u003eConnect V-Band turbine outlet to downpipe using the included V-Band clamp\u003c\/li\u003e\n\u003cli\u003eRoute external wastegate dump port to downpipe or dedicated dump tube\u003c\/li\u003e\n\u003cli\u003eComplete oil feed priming and coolant circuit purging before first engine start\u003c\/li\u003e\n\u003cli\u003eRun initial idle break-in period before operating under full boost\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Garrett","offers":[{"title":"Default Title","offer_id":46152047951951,"sku":"GRT757707-0043","price":899.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1062\/7920\/files\/35726003241039_1.webp?v=1784815762","url":"https:\/\/www.blackopsautoworks.com\/products\/garrett-g38-gxr38-turbine-housing-t4-v-band-0-95-ar-grt757707-0043","provider":"Black Ops Auto Works","version":"1.0","type":"link"}
