• Upgrade Your Turbo: Turbosmart's IWG75 Wastegate Actuator offers maximum boost response for your factory frame turbocharger. • Enhanced Performance: With an improved 'working ratio', it provides better boost response across the RPM range. • Versatile Setup: Choose from springs ranging 3psi to 26psi for customized performance. Turbosmart Upgraded Wastegate Actuators are engineered to deliver the best possible boost response for your factory frame turbocharger. The IWG75 Series boasts an increased 'Working Ratio' compared to factory equipment, which means better boost response throughout the RPM range. This improvement is due to an enlarged diaphragm surface area and revised springs, offering greater leverage against boost and backpressure while remaining highly responsive. Upgrading with the same base pressure as the factory will give you a broader boost and torque curve, reaching peak boost earlier and holding it longer into higher RPM. Higher base pressures can further enhance these improvements, though tuning and recalibration may be needed. Features: - Proprietary Silicon Nomex Diaphragm - Choice of Springs from 3psi to 26psi (Optional) - High Grade Billet Aluminum Construction - Stainless Steel Rods and Clevis - Turbosmart Unique Locking Collar System Notes: The 14 psi version is a direct factory replacement. Other versions require engine ECU tuning/calibration.
