HKS SUPER SQV 4 GT-R BNR32 RB26DETT

If you're looking to get the most out of your twin-turbocharged RB26DETT engine in a GT-R BNR32, managing boost pressure effectively is key. The HKS SUPER SQV 4 (Super Sequential Valve) is a popular choice for this. It's a blow-off valve designed to release excess boost pressure from the intake system when you lift off the throttle, preventing compressor surge and helping to keep your turbochargers healthy.

This particular SUPER SQV 4 unit is built for the specific demands of the BNR32 GT-R's twin-turbo setup. It uses a unique sequential valve structure that HKS developed, which allows for a rapid and complete release of boost pressure. This design helps to minimize the pressure drop in the intake system, leading to a more responsive throttle and quicker spool-up between gear changes. The valve itself is constructed from well-built aluminum, ensuring durability and resistance to the heat and pressure found in the engine bay. It's designed to fit right into the factory plumbing, making installation more straightforward for those familiar with the RB26DETT engine.

When installing, you'll want to ensure all connections are secure to prevent any boost leaks. The distinctive sound of the SUPER SQV 4 releasing boost is a signature of many high-performance Japanese imports. This unit is not CARB approved and cannot be shipped to California.
