The Turbosmart IWG75 is an upgraded internal wastegate actuator that bolts onto the factory VF39, VF43, VF48, and VF52 turbochargers used on EJ25 Subaru WRX STI models and the 2009 to 2014 WRX. A larger effective diaphragm area and revised springs give it a higher working ratio than the factory actuator for improved boost response across the rev range. It is built from billet aluminum with a silicone Nomex diaphragm, stainless steel rod and clevis, and Turbosmart's locking collar, and ships with a 7 psi spring, vehicle specific bracket, fasteners, and swivel hose barb. Optional springs from 3 to 26 psi are available, and retuning may be required.
