Product Description
The Race Port is famous for being an amazingly small and light BOV for turbocharged competition level engines. Featuring our unique collar design and internal flow structures, it is 50% lighter and 25% smaller than the competition while flowing 330 CFM - making it the highest flowing BOV of it’s type on the market. A Blow-Off Valve, sometimes called a diverter valve or bypass valve, is a pressure relief valve that is mounted between the turbo and the intake manifold. It releases excess air pressure when the vehicle comes off throttle. A Blow-Off Valve is an essential part of a turbocharger system, as it prevents damaging turbo compressor surge that can be present on rapid throttle and/or engine load changes, it also increases the response of the turbocharger by not over-slowing the turbine. All Turbosmart Blow-Off Valves are made entirely from billet aluminum, so they will never crack and leak like cast or plastic units do. They also improve boost response from the turbocharger.

Frequently Asked Questions
Will these work on other Skyline Engines?
Unfortunately No. These components are designed specifically for RB26DETT engines, fitted to the GT-R variants and we cannot guarantee, they’re likely to fit any other variant of spec Skyline.
Which Actuator Part Number Should I purchase to work with the Factory Tune?
7 psi is your best bet: Part Number: TS-0615-6072. These will bolt on & work straight away with your factory ECU & tune. Even though they are the same rated pressure as the OE gear, you will still see an improvement in low end response & overall performance. We can achieve peak boost earlier & keep it high in the RPM.
I don’t have the factory blow off plenum, will the Kompact Valve set work?
No, you will need the factory plenum in order to bolt the Kompact set on to your vehicle - These are designed as a factory upgrade. If you do not have the plenum, you may consider our Raceport solution - This sits in the factory position, but deletes the plenum for a simple mounting solution.
Will the Kompact Valves be Loud?
Certainly louder than factory, yes - But you have options. The Smartport solution means you won’t have any technical difficulties venting to the atmosphere, however if BOV noise isn’t your thing we’ve included blanking plus into the kit & you can convert these easily to recirc-only valves. This will mean the same improved performance, but without the noise!
Will these actuators fit upgraded Turbos?
That will depend on your turbo upgrade & if you’re unsure, best check with your turbo supplier. If you have a hybrid upgrade, based around the factory compressor cover then it is very likely these will fit & can be easily adapted.
