Utilizing an External Wastegate with your CorkSport Turbo just got a whole lot easier! Introducing the optional EWG Turbine Housing for the CorkSport CST4 or CST5 Turbos. This will allow you to replace your internally wastegated hotside and utilize an external 44mm wastegate. The external wastegate will bolt to the hotside of the turbo with the included elbow and V-band clamp.

Benefits of going with EWG are better boost control, ease of accessibility to service/change the springs and amazing screamer pipe noises!

Externally Wastegated (EWG) hotside set up includes the necessary EWG installation elbow pipe & V-band clamp.
