Turbosmart Upgraded Wastegate Actuators have been developed to provide the maximum possible boost response for your factory frame turbocharger. The Turbosmart IWG75 Series of upgraded Actuators benefit 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 & 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 & 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.Available In10 PSI / 0.68 BAR: TS-0601-110214 PSI / 1.00 BAR: TS-0601-114218 PSI / 1.24 BAR: TS-0601-118222 PSI / 1.51 BAR: TS-0601-122224 PSI / 1.65 BAR: TS-0601-124226 PSI / 1.79 BAR: TS-0601-1262FeaturesProprietary Silicon Nomex DiaphragmChoice of Springs from 3psi to 26psi (Optional)High-Grade Billet Aluminum ConstructionStainless Steel Rods and ClevisTurbosmart Unique Locking Collar SystemNotes14 psi Version is a direct replacement for the factory item.
