Turbosmart Nissan RB26 RacePort Gen-V Blow Off Valve Black RB26DETT TS-0204-1162

RB26DETT builders in the R32, R33, and R34 GT-R need a blow-off valve that can handle extreme boost and massive power outputs without surge or lag. The Turbosmart Gen-V RacePort 50mm Blow Off Valve in black (TS-0204-1162) is engineered for exactly this purpose. As a direct bolt-on replacement for the factory plenum, it simplifies the system while delivering class-leading airflow and response. Capable of supporting well over 1500 horsepower, this compact valve brings race-proven performance to both track-focused and high-power street Skylines.

Machined from billet 6000 series aluminum with a quick-release V-band collar, the RacePort is significantly lighter and smaller than traditional valves yet flows an impressive 330 CFM through its 2.0-inch inlet. Every detail reflects Turbosmart’s Gen-V engineering: a mil-spec hard anodized valve guide and stem, high-temperature silicon Nomex diaphragm, and positive sealing seat that ensures zero leaks even under the most aggressive boost. Twin 1/8 NPT pressure ports offer flexible mounting options, while five user-configurable corrosion-resistant springs let you fine-tune the valve to your exact boost and driving style. An optional valve position sensor is also available for advanced data logging or ECU integration.

At Terra Firma Automotive, we supply this genuine Turbosmart Gen-V RacePort Blow Off Valve as the top-tier choice for RB26DETT enthusiasts who refuse to compromise on performance or reliability. The valve dramatically reduces compressor surge, sharpens throttle response, and provides consistent operation whether you’re on the street, circuit, or drag strip. Its modular, lightweight design not only improves turbo efficiency and longevity but also gives your engine bay a clean, professional race-inspired look that matches the caliber of a properly built GT-R.
