Turbosmart IWG75 Wastegate Actuator Suit Corsa VXR - 7 PSI (Black)
Upgrade your Corsa VXR's turbo performance with the Turbosmart IWG75 7psi Wastegate Actuator. Featuring a robust billet aluminum construction, proprietary Silicon Nomex diaphragm, and adjustable pre-load, it eliminates wastegate creep and improves boost response. Direct bolt-on fitment for K03 turbochargers on 1.6L Z16LE engines.
The Turbosmart IWG75 Wastegate Actuator (TS-0623-1073) is engineered to provide maximum possible boost response and tighter control over your turbocharger. Designed as a direct bolt-on replacement for the factory actuator on K03 turbochargers found in the 1.6L (Z16LE) turbo motors (including Opel/Vauxhall Corsa VXR, Astra, and Insignia variants), this upgrade eliminates the common pressure drop issues associated with factory rubber diaphragms and weak factory springs.
Constructed from high-grade billet aluminum with a striking black finish, stainless steel rods, and a heavy-duty proprietary Silicon Nomex diaphragm, the IWG75 stays securely shut under high pressures until your boost target is reached. Featuring Turbosmart’s unique locking collar system and fully adjustable pre-load, it allows you to fine-tune your boost onset for maximum performance and reliability.
