Subaru Impreza WRX 1997 - 2007 TURBOSMART 7PSI TD04 Wastegate Actuator IWG75
Turbosmart's high-performance replacement Internal Wastegate Actuator for 1997-2007 WRX models fitted with the TD04 turbo is designed to get better boost response from the WRX's standard turbo, for those who wish to avoid the cost of an aftermarket turbocharger.
The standard pressed steel actuator fitted to the Subaru's TD04 turbocharger is are easily forced open by exhaust gas, meaning it experiences slow boost build up and boost drop at high RPMs. Turbosmart's IWG-75 is therefore fitted with stiffer springs, and features a larger diaphragm area that makes it more difficult for the wastegate to be forced open when it should be closed.
The result is faster boost build up and improved power and torque throughout the rev range. With the Turbosmart IWG, the boost curve is smoother and holds on stronger until the redline.
Furthermore, as these cars age, the standard actuators begin to deteriorate and eventually fail. Turbosmart's IWG-75 is manufactured out of billet aluminium with high quality heat resistant materials used throughout, to ensure excellent reliability.
Includes bracket and fittings. Suits TD04 turbochargers.
