Well I've got the 3b manifold off and taken some pics of the two together.
Will there be an issue using an RS2 turbo to manifold gasket with my current turbo as the 3B on has a raised spigot rather than a flat face?
Need to try and get the studs out of the old manifold unless someone can point me in the direction of new ones?
Could you use standard high temp bolting rather than studs for the wastegate?

If you can't get the old studs out, I just bought a length of high tensile studding and cut my own.

Shouldn't the ports be bigger than 3b? Since Rs2 or, in this case, Wagner copy...
And if not, isn't that much of the reason why go towards Rs2 or Wagner, more flow?
Or the main reason the design for ports #1 and #5 that creates back pressure on exhaust valves for those cylinders?
I'm pondering buying one of those, but on this side the pond I can only source Rs2 copies, not the one you got which is a Wagner copy. I wanted to go Wagner since they seem more sturdy and are supposed to have more flow than Rs2 also. If the flow ports aren't bigger... Might as well get an Rs2 copy from the US.
