The 0.85 A\/R ratio on GRT757707-0037 delivers the quickest spool response in the V-Band inlet G38 housing family, making it the first choice for builds on 2.0L to 3.5L engines where throttle response and mid-range torque are the primary objectives. The V-Band inlet also facilitates easy turbo rotation for optimal oil drain positioning and simplified manifold clearance in tight engine bays.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGRT757707-0037 V-Band inlet \/ V-Band outlet turbine housing for G38 and GXR38 supercores\u003c\/li\u003e\n\u003cli\u003e0.85 A\/R provides fastest spool in the V-Band G38 housing family for responsive builds\u003c\/li\u003e\n\u003cli\u003eDual V-Band connections for leak-free exhaust sealing and easy turbo removal for service\u003c\/li\u003e\n\u003cli\u003eStainless steel construction rated for sustained high-temperature race and street use\u003c\/li\u003e\n\u003cli\u003eExternal wastegate only for full boost pressure control\u003c\/li\u003e\n\u003cli\u003eAllows turbo rotation for optimized oil drain line routing in tight installations\u003c\/li\u003e\n\u003cli\u003eIncludes gasket kit, V-Band clamps, 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\u003eGRT757707-0037 \/ 757707-0037\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\u003eV-Band (open\/undivided)\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\u003e0.85\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 GRT757707-0037 G38\/GXR38 Turbine Housing Kit\u003c\/li\u003e\n\u003cli\u003eGasket kit\u003c\/li\u003e\n\u003cli\u003eV-Band clamps for inlet and 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 produces the G38 turbine housing family in both T4 divided and V-Band inlet configurations across three A\/R ratios, giving builders maximum flexibility to match the housing to their manifold design and performance objectives. The V-Band inlet versions are preferred in competition builds and high-end street cars utilizing custom V-Band exhaust manifolds.\u003c\/p\u003e\u003ch4\u003eFAQ\u003c\/h4\u003e\u003cstrong\u003eWhat is the GRT757707-0037?\u003c\/strong\u003e\u003cp\u003eThe GRT757707-0037 is a Garrett G38\/GXR38 turbine housing featuring a V-Band inlet and V-Band outlet with a 0.85 A\/R ratio. It is the quickest-spool V-Band inlet option in the G38 housing family and is sold as a standalone kit requiring a compatible G38 or GXR38 supercore to complete the turbocharger assembly.\u003c\/p\u003e\u003cstrong\u003eWhat is the advantage of V-Band inlet over T4 divided on the G38?\u003c\/strong\u003e\u003cp\u003eA V-Band inlet allows full turbo rotation for flexible oil drain positioning, provides an easier manifold connection with fewer fasteners, and gives better manifold clearance in tight engine bays. However, V-Band inlets are typically undivided (single scroll), so they do not preserve exhaust pulse energy in the same way a divided T4 manifold does.\u003c\/p\u003e\u003cstrong\u003eWhat supercores are compatible with GRT757707-0037?\u003c\/strong\u003e\u003cp\u003eGRT757707-0037 fits the G38-1000 supercore (938272-5003S) and the G-XRace GXR38-64 supercores (934173-5008S and 934173-5009S). It is not compatible with G40, G42, or other frame supercores.\u003c\/p\u003e\u003cstrong\u003eDoes GRT757707-0037 require an external wastegate?\u003c\/strong\u003e\u003cp\u003eYes. All G38 turbine housing kits are externally wastegated. An external wastegate must be sourced and installed separately.\u003c\/p\u003e\u003cstrong\u003eWhat displacement is GRT757707-0037 best suited for?\u003c\/strong\u003e\u003cp\u003eThe 0.85 A\/R V-Band housing is optimized for 2.0L to 3.5L builds targeting strong mid-range power and quick spool. Larger displacement builds or those targeting peak power above 800 horsepower should consider the 0.95 or 1.06 A\/R options.\u003c\/p\u003e\u003cstrong\u003eIs the V-Band inlet clamp included?\u003c\/strong\u003e\u003cp\u003eYes. GRT757707-0037 includes V-Band clamps for both the turbine inlet and turbine outlet connections, along with the gasket kit and mounting hardware.\u003c\/p\u003e\u003cstrong\u003eCan the turbo be rotated with this housing?\u003c\/strong\u003e\u003cp\u003eYes. A key advantage of the V-Band inlet configuration is that the turbocharger can be rotated relative to the manifold connection for optimal oil drain positioning, which is not possible with fixed T4 flanged housings.\u003c\/p\u003e\u003cstrong\u003eIs GRT757707-0037 a twin-scroll or single-scroll housing?\u003c\/strong\u003e\u003cp\u003eGRT757707-0037 is a single-scroll (open\/undivided) V-Band inlet housing. For twin-scroll exhaust pulse energy retention, use the T4 divided inlet versions GRT757707-0042, 0043, or 0044.\u003c\/p\u003e\u003ch4\u003eInstallation Overview\u003c\/h4\u003e\u003col\u003e\n\u003cli\u003eVerify the G38 or GXR38 supercore is assembled with oil and coolant fittings installed\u003c\/li\u003e\n\u003cli\u003eAlign the V-Band turbine inlet to your V-Band exhaust manifold outlet and clamp using the included V-Band inlet clamp\u003c\/li\u003e\n\u003cli\u003eRotate the turbo assembly to the optimal position for oil drain routing before fully tightening the inlet V-Band clamp\u003c\/li\u003e\n\u003cli\u003eConnect the V-Band turbine outlet to the downpipe using the included outlet V-Band clamp\u003c\/li\u003e\n\u003cli\u003eInstall external wastegate to manifold dump port\u003c\/li\u003e\n\u003cli\u003ePrime oil system before first start and bleed coolant circuit\u003c\/li\u003e\n\u003cli\u003eAllow idle break-in before operation under boost\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Garrett","offers":[{"title":"Default Title","offer_id":46152047558735,"sku":"GRT757707-0037","price":849.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1062\/7920\/files\/35726002880591_1_b21a7a30-19b3-41e8-b382-8b578129c9e8.webp?v=1784815709","url":"https:\/\/www.blackopsautoworks.com\/products\/garrett-g38-gxr38-turbine-housing-v-band-v-band-0-85-ar-grt757707-0037","provider":"Black Ops Auto Works","version":"1.0","type":"link"}
