Still made of forged aluminum and based on a dual piston conception, this new version features a revised design while ensuring 100% backward compatibility thanks to its perfectly identical flange and dimensions. A new manufacturing process ensures even more reliability, and brings two major innovations: The opening pressure of the G Reddy FV2 dump valve is now adjustable with a knob. The body of the dump valve can be rotated 360° to facilitate its installation in narrow engine bays. The new G Reddy FV2 black blow off valve ensures both stable idling and an extremely quick opening and closing time, even at low boost pressures. These unique abilities guarantee the highest reliability for any type of use, all while optimizing the turbo spool (maintains the rotation speed during gear changes for an improved response time / anti-lag properties). This kit for Subaru Impreza GRB was developed and approved by G Reddy in Japan, and contains everything needed for a plug & play installation. It allows two types of installation: return or vent to atmosphere.
