Your Stock Nissan GTR is quick car but adding a HKS GT570 Racing Tune Kit will make your GTR very fast. The HKS's GT570's Racing Tune Kit is an industry standard for quality and performance. HKS uses a pull type valve to ensure that this will never leak with any amount of boost. Unlike typical push type blow off valves, the HKS SQV will not leak under any level of boost because the boost pressure keeps the valve closed against its seat. This ensures a quick valve response and complete closure during idle. Many competitors use a push type blow off valve design with a large valve to accommodate high boost / high horsepower applications.

These large valves react slowly and require high pressure to open, and are not able to activate and prevent compressor surge at light load conditions. The GTR uses two of these valves to relieve boost pressure from the twin turbo. This setup is highly effective and recirculates air quickly to prevent compressor surge. HKS has designed these to work on stock up to highly modified GTR. The standard Nissan GT-R R35 kit is rated at 480 HP, but this kit is brings that number just over 570 HP at the flywheel by way of a new exhaust, intake pipe kit, boost controller and wastegate actuators. The GT570's Racing Package is intended for off-road / motorsports use only. The GT570's package is not covered under HKS warranty and is sold as-is. So forget those thoughts of having a factory parts on your GTR and take a look at the HKS GT570 Racing Tune Kit today.
