RB20DET and RB25DET engines in the R32, R33, and R34 Skyline platforms benefit from a blow-off valve that balances performance and drivability. The Turbosmart Kompact Dual Port Blow Off Valve (TS-0203-1026) delivers this with its sequential port design that vents both to atmosphere and back into the intake. Under hard acceleration it provides the sharp, satisfying blow-off sound enthusiasts love, while remaining quiet during normal driving for comfortable daily use.
This compact valve improves throttle response and reduces compressor surge, protecting your turbocharger while enhancing overall boost control. Its precision-engineered body ensures a secure fit in the tight RB engine bays, making it an ideal upgrade for stock to lightly modified setups. The dual-port system gives you the best of both worlds — motorsport excitement when you want it and refined operation when you don’t.
At Terra Firma Automotive, we supply this genuine Turbosmart Kompact Dual Port Blow Off Valve as a premium upgrade for RB20 and RB25 Skyline owners. It combines OEM-like fitment with aftermarket performance, delivering reliable operation and an engaging driving experience.

Questions & Answers
Ask a Question-
Can this bov be taken off the flange so that I can use it without oem crossover pipe someday? I have the crossover pipe right now but when I get an intercooler I am thinking of blocking out the recirculating port.
Hi, i looked over the unit in stock and doesn't seem to be a clear way to remove the flange. Thanks!
