GFB T9004 Respons TMS Blow Off Valve Kit – Nissan Silvia S14/S15 SR20DET

Upgrade your Nissan SR20DET turbo setup with the GFB T9004 Respons TMS Blow Off / Diverter Valve Kit. Designed for Nissan Silvia S14 and S15 SR20DET applications, the Respons TMS valve gives you adjustable sound control with the ability to bias the valve between recirculation and atmosphere venting.

Unlike a fixed vent-to-atmosphere blow off valve or a basic recirculating diverter valve, the GFB Respons TMS design lets you adjust how much air is recirculated and how much is vented to atmosphere. This allows the valve to be tuned for quieter factory-style operation, louder blow-off sound, or a balanced setting in between.

The Respons TMS valve is designed to improve throttle response, boost recovery between shifts, and boost-holding performance while maintaining better drivability on sensitive airflow-meter based systems when adjusted correctly. This makes it a strong upgrade for street-driven, tuned, drift, and performance SR20DET builds.
