Turbosmart IWG75 Mitsubishi Evo 4-8 18 PSI Internal Wastegate Actuator – Performance Boost Response

Description

Upgrade your Mitsubishi Evolution 4-8 with the Turbosmart IWG75 Series Internal Wastegate Actuator, designed to maximize boost response for factory frame turbochargers. Constructed from high-grade billet aluminum, this actuator features a proprietary silicon Nomex diaphragm and stainless steel rods and clevis for durability and precision. Its unique locking collar system ensures secure fitment and reliable operation. The IWG75 provides an increased working ratio over stock components, resulting in noticeably improved boost response across the entire RPM range, which enhances overall engine performance and throttle responsiveness.
This actuator is a direct bolt-on replacement for the factory unit on the TD05H turbocharger, specifically fitted to the 46G3-powered Mitsubishi Evolution models from 2003 to 2008. It offers a 14 psi boost pressure setting as standard, with options for springs that allow tuning from 3 psi up to 26 psi, depending on your performance requirements. Note that other boost levels will require ECU tuning or calibration to ensure optimal engine operation. Designed for ease of installation, the Turbosmart IWG75 provides a significant upgrade over factory wastegate components, making it an excellent choice for enthusiasts seeking better turbo response and boost control.
This product complies with Prop 65 regulations and is suitable for air freight shipping. It is not CARB approved, and installation may require acknowledgment of specific regulations.
