Product Description

The Turbosmart TS-0203-1072 Kompact SmartPort Dual Port Blow-Off Valve Set is a performance upgrade engineered specifically for the Nissan Skyline GT-R series equipped with the legendary RB26DETT twin-turbo engine from 1989 through 2002. Designed as a direct replacement for the factory blow-off valves, this set uses SmartPort technology to maintain proper ECU and airflow meter operation while providing improved boost control and turbo response compared to stock.

Featuring a dual-port design that vents to both the atmosphere and intake with 50/50 balance, the TS-0203-1072 delivers smooth operation under light boost and an engaging blow-off sound under higher loads. The modular design allows you to remove the vent-to-atmosphere trumpets and install the supplied blanking plugs for full recirculating operation when a quieter setup is preferred. Precision billet aluminum construction with a black anodized finish ensures durability and resistance to heat and corrosion. Ideal for enthusiasts restoring or enhancing their Skyline GT-R's turbo system, this blow-off valve set improves boost management and throttle response while retaining reliability.
