The Turbosmart IWG75 internal wastegate actuator increases boost response over factory equipment by raising the working ratio for quicker spool and better control across the RPM range. Constructed with high-grade billet aluminum, stainless steel rod and clevis, and a proprietary silicone-Nomex diaphragm, it accepts spring choices from 3–26 psi and uses Turbosmart’s locking collar for secure adjustment.
