Unlike fixed-ratio atmospheric BOVs that can cause backfiring and stalling on modern MAP-sensor-equipped engines, the Respons uses GFB's patent-pending TMS Technology to let you dial in the balance between atmosphere venting and recirculation. You get the blow-off sound you want without sacrificing boost recovery speed or driveability. The GFBT9004 also includes all the application-specific adapters and fittings needed for a direct-fit installation on the Silvia S14\/S15 platform.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGFBT9004 TMS Technology lets you independently adjust the amount of atmosphere venting versus recirculation\u003c\/li\u003e\n\u003cli\u003eEliminates the backfiring and stalling caused by fully atmospheric BOVs on MAP-sensor-equipped engines\u003c\/li\u003e\n\u003cli\u003eRapid boost recovery on gear shift compared to standard piston-type valves\u003c\/li\u003e\n\u003cli\u003eRated to 100+ psi boost capacity for any forced induction application\u003c\/li\u003e\n\u003cli\u003eAdjustable for both street and performance driving without removing the valve\u003c\/li\u003e\n\u003cli\u003eIncludes Nissan Silvia S14\/S15 direct-fit adapter and hoses for bolt-on installation\u003c\/li\u003e\n\u003cli\u003eAnodized aluminum body construction for durability and heat resistance\u003c\/li\u003e\n\u003cli\u003eCompatible with both factory and aftermarket turbos on the SR20DET engine\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYear Range\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eTrim\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e1994-1998\u003c\/td\u003e\n\u003ctd\u003eNissan\u003c\/td\u003e\n\u003ctd\u003eSilvia\u003c\/td\u003e\n\u003ctd\u003eS14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1999-2002\u003c\/td\u003e\n\u003ctd\u003eNissan\u003c\/td\u003e\n\u003ctd\u003eSilvia\u003c\/td\u003e\n\u003ctd\u003eS15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eGFBT9004\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGo Fast Bits (GFB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003e1994-2002 Nissan Silvia S14\/S15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eValve Type\u003c\/td\u003e\n\u003ctd\u003eBlow Off Valve (BOV)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTechnology\u003c\/td\u003e\n\u003ctd\u003eTMS (Turbo Management System)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Boost Rating\u003c\/td\u003e\n\u003ctd\u003e100 psi+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003eAnodized Aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdjustment\u003c\/td\u003e\n\u003ctd\u003eExternal, tool-free vent ratio adjustment\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eMAP sensor equipped SR20DET, aftermarket turbos\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e9318396028793\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGFB GFBT9004 TMS Respons BOV body\u003c\/li\u003e\n\u003cli\u003eNissan Silvia S14\/S15 direct-fit adapter plate\u003c\/li\u003e\n\u003cli\u003eInlet and outlet hoses and clamps\u003c\/li\u003e\n\u003cli\u003eHardware pack and installation instructions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eAbout Go Fast Bits\u003c\/h4\u003e\u003cp\u003eGo Fast Bits (GFB) is an Australian-engineered performance valve brand founded in 1997, specializing in blow off valves, diverter valves, and boost controllers. GFB pioneered the TMS (Turbo Management System) technology that allows drivers to tune the vent ratio of their BOV to suit their specific engine management system, eliminating the compromise between sound and driveability that was common with earlier atmospheric valves.\u003c\/p\u003e\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\u003cstrong\u003eWill the GFBT9004 cause backfiring or stalling on my SR20DET-powered Silvia?\u003c\/strong\u003e\u003cp\u003eNo. The GFBT9004's TMS Technology allows you to blend the atmosphere vent ratio so your MAP sensor does not see a sudden pressure drop that causes the ECU to enrich fueling and cause backfires or stalls. You can tune the sound level while preserving drivability.\u003c\/p\u003e\u003cstrong\u003eCan I run the GFBT9004 fully atmospheric for maximum blow-off sound?\u003c\/strong\u003e\u003cp\u003eYes. The Respons can be adjusted to vent fully to atmosphere if your engine management allows it. On cars with MAP-based fueling, full atmospheric venting may cause drivability issues. TMS allows you to find the right balance for your specific tune.\u003c\/p\u003e\u003cstrong\u003eIs the GFBT9004 compatible with the factory SR20DET turbo on the S14 and S15?\u003c\/strong\u003e\u003cp\u003eYes. The GFBT9004 is compatible with both the factory IHI RHF5 turbocharger on the Nissan Silvia S14\/S15 SR20DET and most common aftermarket turbo upgrades for this platform.\u003c\/p\u003e\u003cstrong\u003eDoes the GFBT9004 fit the Nissan 200SX as well as the Silvia?\u003c\/strong\u003e\u003cp\u003eThe GFBT9004 is designed for the S14\/S15 Silvia chassis. Fitment on the 200SX (S13 platform) would require different adapters. Verify the application before purchasing for S13-based vehicles.\u003c\/p\u003e\u003cstrong\u003eHow do I adjust the vent ratio on the GFBT9004?\u003c\/strong\u003e\u003cp\u003eThe Respons features an external adjustment knob that controls the balance between atmospheric venting and recirculation. Turning it clockwise increases recirculation (quieter, more drivability-friendly). Counterclockwise increases atmosphere venting (louder). Adjustment can be made without tools and without removing the valve.\u003c\/p\u003e\u003cstrong\u003eWhat boost pressure can the GFBT9004 handle?\u003c\/strong\u003e\u003cp\u003eThe GFB Respons is rated for 100+ psi boost capacity, far exceeding what any factory or typical aftermarket street turbo setup on an S14\/S15 Silvia would produce.\u003c\/p\u003e\u003cstrong\u003eDoes the GFBT9004 come with all the hoses and fittings needed for my Silvia?\u003c\/strong\u003e\u003cp\u003eYes. The GFBT9004 kit includes the direct-fit adapter plate for the Nissan Silvia S14\/S15, along with the inlet and outlet hoses, clamps, and all hardware required for installation.\u003c\/p\u003e\u003cstrong\u003eIs the GFBT9004 legal for street use in California?\u003c\/strong\u003e\u003cp\u003eThe GFBT9004 is a BOV\/bypass valve modification. Emissions and street legality for BOV modifications vary by state and local jurisdiction. In California, BOV modifications are subject to smog check inspection.
