The bolt size is an M10x1.25 (or 1.5, I don't remember, but it's the same size/pitch as the ETD manifold flange for the turbo). If you have the JGS basic oil return kit with the aluminum flange, the hole will be smaller than the bolt, so you will need to get a drill and tap it one size bigger.
Oh, and I have the T4 with a T3 turbine, but oil return should be the same.
