Still made of forged aluminum and based on a dual-piston design, 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 greater reliability and brings two important innovations: The opening pressure of the GReddy FV2 blow-off valve is now adjustable with a knob. The blow-off valve body can rotate 360° to facilitate installation in cramped engine compartments. The new GReddy FV2 black blow-off valve ensures both stable idling and extremely fast opening and closing times, even at low boost pressures. These unique capabilities guarantee maximum reliability for any type of use, all while optimizing turbo spool (maintains rotational speed during gear changes for improved response time / anti-lag properties). This kit for Subaru Impreza GRB was developed and approved by GReddy in Japan, and contains everything needed for a plug & play installation. It allows for two types of installation: return or vent to atmosphere.
