Turbosmart IWG75 Wastegate Actuators are engineered to deliver maximum boost response and performance from your factory frame turbocharger. Designed as a direct upgrade over OEM actuators, the IWG75 Series offers a significant improvement in turbo control, responsiveness, and efficiency across the full RPM range.
This improvement is made possible by an increased working ratio, achieved by expanding the effective diaphragm surface area and optimising internal spring design. This enhanced leverage allows the actuator to better manage forces such as boost pressure and exhaust backpressure while maintaining fast and precise response.
When installed with the same base pressure as the factory unit, these actuators offer improved performance without requiring ECU tuning. However, when fitted with a higher base pressure spring, additional tuning and recalibration are recommended to fully realise the gains.
Available options:
12psi / 0.8 BAR – TS-0622-9122
14psi / 0.9 BAR – TS-0622-9142
Features:
-
Proprietary silicone Nomex-reinforced diaphragm
-
Optional spring selection from 3psi to 26psi
-
High-grade CNC-machined billet aluminium construction
-
Stainless steel rods and clevis for corrosion resistance
-
Unique Turbosmart locking collar system for quick and easy spring changes
Notes:
The 12psi actuator is a direct replacement for the factory item and typically does not require tuning. The 14psi version and higher pressure setups may require ECU calibration for optimal performance and reliability.
