SBR 340 WRX EJ25
Size
Our Stage three tuning option for the Impreza WRX is ideal for Subaru owners wanting to improve performance for road cars. First, we swap the stock turbo for our VF Billet hybrid. We then replace the stock cats with a high-flow sports cat, Race cat up-pipe and non-resonated centre section to improve flow. We then swap the stock fuel pump for the RCM 340 to ensure good fuel delivery. Finally, we add a high-flow panel filter to improve engine breathing and a three-port boost solenoid for sharper boost control. Your car is then mapped on the road optimising throttle response for peak power and mid-range. The result is a greatly improved power band with a boost target being achieved sooner and holding for longer across the RPM range. Your map will retain all the factory functions your used to along with the improved safety functions. Please consider power figures may vary based on engine condition and millage. We spend an average of 2-3 hours mapping each car.
