Turbosmart IWG75 Internal Wastegate Actuator Mitsubishi Evo 9 (CT9A)

Turbosmart IWG75 Internal Wastegate Actuator - Mitsubishi Evo 9 (CT9A)

Turbosmart is an Australian engineered brand with a strong reputation in forced induction, and their IWG75 Internal Wastegate Actuator is a genuine step up from the factory unit. Designed to extract more from your turbocharger without swapping the housing, it delivers a broader boost and torque curve by getting to peak boost earlier and holding it deeper into the rev range. Bolt it on and feel the difference.

This listing covers the IWG75 actuator for the Mitsubishi Lancer Evolution 9 (CT9A), fitted with the TD05H turbocharger as standard. It is a direct bolt-on replacement for the factory actuator on this application. Six spring pressure options are available — from 10 psi (0.68 bar) through to 26 psi (1.79 bar) — selectable via the variant selector on this page.

Important: The 14 psi variant is a direct drop-in replacement for the factory actuator and requires no ECU recalibration. All other spring pressures will require tuning and ECU recalibration before use.
