Description
Turbosmart - IWG75 Wastegate Actuator 7PSI - 1997-2007 Subaru WRX TD04
Maximize boost response with Turbosmart's IWG75 Wastegate Actuator upgrade for your stock turbocharger. Experience improved boost response and RPM range thanks to the increased "Working Ratio" of the upgraded actuator.
This upgraded 'working ratio' is achieved by enlarging the diaphragm's effective surface area and revising the installed springs, allowing for greater leverage on the forces that the actuator must counteract (boost and backpressure). The result is improved responsiveness while maintaining high levels of precision.
Upgrading with the same base pressure as factory, you can expect a broader boost & torque curve through peak boost being achieved earlier in the RPM and being held longer, into higher RPM. These improvements can be amplified with higher base pressures, however tuning & recalibration is likely required.
