Turbosmart IWG75 Internal Wastegate Actuator For Mitsubishi EVO 4-8 Blk 22 PSI TS-0601-1222

Turbosmart IWG75 Internal Wastegate Actuator For Mitsubishi EVO 4-8 Blk 22 PSI

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 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 being achieved earlier in the RPM and being held longer into higher RPM. These improvements can be amplified with higher base pressures. However, tuning and recalibration are likely required.

Frequently asked questions

What is a wastegate actuator?

A wastegate actuator controls the opening of the wastegate, regulating boost pressure in turbocharged engines.

How do I install the Turbosmart IWG75 actuator?

Installation involves removing the factory actuator and replacing it with the Turbosmart unit, ensuring proper alignment and securing all connections.

Is tuning required after installation?

Yes, tuning and recalibration are often necessary to optimise performance after upgrading the actuator.

Can this actuator be used with other turbochargers?

While primarily designed for Mitsubishi EVO 4-8 models, it may be compatible with other setups depending on specific requirements.

What boost levels can I achieve with this actuator?

This actuator can handle up to 22 PSI, but actual boost levels will depend on your vehicle's setup and tuning.
