Easy power up. Just replace with stock actuator. It enables higher boost and power will be increased. It is the first step of tuning while stock turbine still can be used.
Works Engineering actuator kit provides rod length adjustment to provide better boost control up to 1.0bar of boost manually. Boost range higher than 1.2bar can be achieved with aide of aftermarket boost controllers to direct signals to the wastegate actuator for higher boost pattern. It is recommended to upgrade the stock actuator for people looking to boost at or beyond 14psi. Adjustment should be done carefully with couple turns at a time.
Available for Nissan R35, Mitsubishi Evo X and Subaru WRX STI.
