Wastegate Interchangeability - Which wastegates clamp to the same flange?

Most turbo headers or exhaust manifolds come flanged for a particular wastegate. The two most common flanges we see are the Tial MVR flange and the Tial MVS flange. 

Even within the Tial line up, there are several varations of these wastegates that will clamp to the same flange. But other manufacturers have started designing their wastegates to be interchangeable as well. Now you can clamp wastegates like Precision or Turbosmart to the same flange you would clamp your Tial to. 

Below we will go over which wastegates are interchageable with eachother. 

Tial MVS Flange

• Tial MVS 38mm
• Tial MVSA 38mm
• Precision 40mm
• Turbosmart Compgate 40mm

Tial MVR Flange

• Tial MVR 44mm
• Precision 46mm
• Turbosmart Hypergate 45mm
• Forge Motorsport 44mm
