Turbosmart IWG75 Wastegate Actuator - Garrett GTX28R - 7psi
The Turbosmart IWG75 is an upgraded internal wastegate actuator for the Garrett GTX28R turbocharger. A larger effective diaphragm area and revised springs give it a higher working ratio for earlier, more sustained boost and a broader torque curve.
Note: Supplier fitment references GTX28R installations on SR20 engines - please confirm your setup. 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
- 7psi outer spring (pink) pre-fitted
- Fasteners and swivel hose barb
