Turbosmart IWG75 Single Port Internal Wastegate Actuator

**For Twin Port EFR applications, check out Turbosmart's new GenV actuator.

The Turbosmart wastegate actuator range has been designed as a premium performance upgrade. Most importantly the IWG75 gives you the ability to change the spring rate, putting you in control of your boost response! On an internally wastegated turbo, the wastegate valve is built into the turbine housing. The wastegate valve is controlled by an internal wastegate actuator (aka canister). As boost rises the actuator controls the position of the wastegate valve, which in turn controls the exhaust gas flow to the turbine.

The Turbosmart IWG-75 actuator range features:

Base spring pressure available from 3PSI to 26PSI
Stable boost control
Improved boost response
Flatter boost curve in the top end
A range of vehicle/turbo specific applications

The wastegate actuator allows for different combinations of spring pressures. All springs that are adaptable with the wastegate actuator are shown in the table below. To aid in the identification of these springs they are supplied colour coded. If this colour coding is not clear please use the dimensions in the following table to identify the spring. The springs chosen should be rated to the lowest boost level desired. Typically with a single port IWG, the stiffer the spring the earlier a given turbo will spool, since the WG does not bypass any exhaust gas during spoolup.

WARNING!

Fitting a heavier wastegate actuator spring may cause a higher than expected increase in boost pressure.
Turbosmart recommends adjusting your boost controller back to its minimum setting (or unplugging the solenoid) and measuring the new minimum boost pressure achieved by the new spring, before increasing your boost pressure again.
Use of a turbocharger speed sensor is a good idea if you plan to run very high boost levels
