Turbosmart IWG75 Twin Port Wastegate Actuator - BorgWarner EFR B2 - 14psi
The Turbosmart IWG75 Twin Port is an upgraded internal wastegate actuator for BorgWarner EFR B2 single and twin scroll turbos. Twin port control lets boost be fed to the top cap for a higher boost target or under the diaphragm for a lower one, widening the control window around base spring pressure and often allowing a softer spring for better response.
Note: Running a higher base spring pressure than factory is likely to require ECU tuning and recalibration. Installation by a professional is recommended.
What's Included
- IWG75 wastegate actuator
- Spring pre-fitted to the listed pressure
- Fasteners and swivel hose barb
