Turbosmart IWG75 Subaru WRX MY15 07 PSI

IWG75 Subaru WRX MY15 07 PSI

The Turbosmart IWG75 Upgraded Wastegate Actuator is designed to deliver maximum boost response for factory-frame turbocharger systems. It improves boost control, spool response, and overall consistency across the entire RPM range compared to OEM actuators.

This performance gain comes from an increased working ratio, achieved by enlarging the diaphragm’s effective surface area and revising internal spring calibration. This increases mechanical leverage against boost pressure and exhaust backpressure while maintaining fast, stable actuator response.

When matched with factory base pressure, the result is earlier boost onset, a broader torque curve, and improved boost retention into higher RPM. Higher base pressure setups can further enhance performance, although ECU tuning and recalibration are recommended.
