IWG75 Universal Actuator (UNF) 150mm 14PSI

IWG75 Universal Actuator (UNF) 150mm 14PSI

The Turbosmart IWG75 Upgraded Wastegate Actuator is engineered to deliver maximum boost response and control for factory frame turbochargers. Designed as a performance upgrade over OEM actuators, the IWG75 series improves boost stability, spool characteristics, and overall engine performance across the entire RPM range.

Product Overview

The IWG75 actuator features an increased working ratio compared to factory units. This is achieved through a larger effective diaphragm surface area combined with revised spring design, allowing greater leverage against boost pressure and exhaust backpressure while maintaining excellent responsiveness.

Upgrading with the same base pressure as factory delivers noticeable performance gains, including:

• Earlier boost onset
• Broader boost and torque curve
• Improved boost hold into higher RPM

Higher base pressure setups can further enhance performance, though tuning and recalibration may be required.

Available Options

• Twin Port Universal (UNF) – 14psi / 1.0 Bar (TS-0681-6142)
• Single Port Universal (UNF) – 14psi / 1.0 Bar (TS-0681-5142)
