Turbosmart IWG75 Actuator for Subaru Forester XT WRX EJ255 EJ205 EJ207 EJ25

Turbosmart's high-performance Internal Wastegate Actuator for 1997-2007 WRX models equipped with the TD04 turbo is engineered to get a better boost response from the standard WRX turbo, for those who wish to avoid the cost of an aftermarket turbocharger. The standard pressed steel actuator fitted to Subaru’s TD04 turbocharger is easily blown open by exhaust gases, meaning you experience slow boost build-up and boost drop off at high RPMs. Turbosmart's IWG-75 is therefore fitted with stiffer springs and features a larger diaphragm area making it harder for the wastegate to be forced open when it should be closed. The result is faster boost build-up, and improved power and torque across the rev range. With the Turbosmart IWG, the boost curve is smoother and holds stronger all the way to the redline. Furthermore, as these cars age, standard actuators begin to deteriorate and eventually fail. The Turbosmart IWG-75 is constructed from billet aluminum with high-quality heat-resistant materials to ensure excellent reliability. Includes bracket and hardware. Compatible with TD04 turbochargers.
