Product Description

The Turbosmart TS-0605-5072 IWG75 Internal Wastegate Actuator is a performance-oriented replacement designed to enhance wastegate control on Subaru models equipped with the factory TD04 turbocharger. With a 7 PSI base spring installed, this actuator maintains similar boost levels to the factory unit while improving boost response thanks to the increased diaphragm surface area and optimized spring characteristics. The result is a more responsive boost curve with improved torque delivery and smoother acceleration through the power band.

Built with a billet aluminum housing, a reinforced Silicon Nomex diaphragm, and stainless steel rod components, the TS-0605-5072 delivers durability under high temperature and high-pressure operating conditions. The locking collar system ensures the preload remains secure, and optional springs allow further customization for tuned builds. Installation is straightforward with the included vehicle-specific bracket and hardware, making it a direct bolt-on for 1997-2007 Subaru Impreza WRX and compatible Forester XT applications.

While this actuator retains a factory-equivalent base pressure for street and mild performance applications, enthusiasts seeking higher boost levels should consider spring upgrades and appropriate ECU tuning to maintain safe air-fuel ratios and boost control throughout the RPM range.
