Product Description

The Turbosmart TS-0601-1142 internal wastegate actuator is a high-quality performance upgrade engineered for Mitsubishi Lancer Evolution models from 1999 through 2005. Designed as a direct fit replacement for the factory internal wastegate actuator, it offers improved boost response and more consistent control of the turbocharger's internal wastegate. With a 14 PSI base spring pre-installed, this actuator maintains factory base boost while providing a broader torque curve and sharper throttle response - ideal for both street and tuned applications.

Constructed from high-grade billet aluminum and features a Nomex-reinforced silicone diaphragm and stainless steel rod/clevis to withstand high temperatures and harsh conditions. The Turbosmart locking collar system allows quick and easy spring changes, letting you fine-tune performance with optional springs for higher base pressures when paired with ECU tuning. Whether you're refreshing a worn OEM actuator or upgrading for better performance, the TS-0601-1142 delivers durable, responsive boost control for Evo 6-8 turbo engines.
