Product Description

The Turbosmart TS-0204-1162 Gen-V RacePort Blow-Off Valve (BOV) is a high-performance turbo pressure relief solution engineered specifically for turbocharged **Nissan Skyline GT-R** models equipped with the **RB26DETT engine (1989-2002)**. Its RacePort design delivers excellent airflow in a compact, lightweight build - roughly 50 % lighter and 25 % smaller than many traditional blow-off valves - while still providing strong boost stability and smooth pressure transitions under high-boost conditions. Perfect for performance, track, and heavily modified turbo systems, this valve helps reduce compressor surge and maintain consistent boost control during throttle lift-off.

Constructed from premium 6000-series billet aluminum with a durable hard-anodized finish, the TS-0204-1162 includes a quick-release V-band collar and dual 1/8 NPT reference ports for flexible vacuum/boost line routing. The 50 mm inlet provides more than adequate flow capacity (~330 CFM) for high-power builds, and configurable springs allow tuners to adjust response to match specific boost targets. Designed as a direct bolt-on replacement for the original blow-off/plenum setup on the **R32, R33, and R34 Skyline GT-R**, this valve delivers both performance and reliability for RB26DETT applications.
