What's the official port size on a T3 flange? I've tried Googleing it and there seems to be loads of different drawings out there.

I want the port size, not the bolt centres. I've noticed that there is a lot of difference between the port in the exhaust manifold, the gasket and the turbo port. I guess it does not matter what the official size is, I'll just make them all match the biggest.sigpic
