Product Description

The Turbosmart TS-0203-1226 Kompact Plumb Back Blow-Off Valve is a full recirculating turbo boost relief valve designed for Nissan turbo performance cars, including classic Skyline GTS-T models (R32/R33/R34) and Stagea Turbos, with suitable applications on GT-R platforms when used with proper flanges and two kits. Its plumb back design recirculates all excess boost air back into the intake system rather than venting to the atmosphere, helping maintain consistent boost control, reduce noise, and improve overall turbo system response.

Constructed from precision billet aluminium with a compact Kompact body and a green spring installed for balanced actuation, this valve offers superior durability and performance over stock plastic bypass valves. It's ideal for enthusiasts who want improved reliability and quiet performance on high-boost applications without the loud whoosh of vent-to-atmosphere blow-off valves. Before installation, make sure your vehicle's flange and piping match this plumb back design, and confirm local emission regulations, because this part is generally intended for competition or off-road use in emissions-controlled areas.
