Turbosmart Upgraded Wastegate Actuators have been developed to deliver the maximum possible boost response for your factory-frame turbochargers. The Turbosmart IWG75 Series of upgraded Actuators benefits from an increased Working Ratio over the factory equipment, resulting in improved boost response throughout the RPM range.

This improved working ratio is achieved through an increase to the effective surface area of the diaphragm and revisions to the actual springs fitted, resulting in greater leverage of the forces the actuator is working against (boost and backpressure) while still being super-responsive.

Upgrading with the same base pressure as the factory, you can expect a broader boost and torque curve through peak boost achieved earlier in the RPM and hold longer into higher RPM. These improvements can be amplified with higher base pressures. However, tuning & recalibration are likely required.

Available In:

• 7psi / 0.50 BAR:TS-0615-2072
• 19psi / 1.31 BAR: TS-0615-2192

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 7psi version is a direct replacement for the factory item. All other versions will require tuning/calibration of your engines ECU.

This is a bolt-on fitment for the turbochargers as fitted factory to the VR38 3.8 Liter Twin Turbo Powered Nissan GT-R R35 from 2007-2024.
