Turbosmart IWG75 Wastegate Actuator - Subaru WRX (GC/GD) TD04 Turbo - 7psi
The Turbosmart IWG75 is an upgraded internal wastegate actuator for the TD04 turbocharger fitted to the 1997-2007 Subaru WRX. A larger effective diaphragm area and revised springs give it a higher working ratio than the factory actuator, so peak boost arrives earlier in the rev range and is held for longer, giving a broader boost and torque curve.
Note: Suits TD04-equipped cars only - please confirm your turbo before ordering. Running a higher base spring pressure than factory is likely to require ECU tuning and recalibration. Installation by a professional is recommended.
What's Included
- IWG75 wastegate actuator
- Vehicle-specific mounting bracket
- Spring pre-fitted to the listed pressure
- Fasteners and swivel hose barb
