I know all about turbo's fouling on things!!! I finished my custom manifold for the T03 and decided to check if the engine mounts fitted, this was after I spent 100 bucks on getting the flanges milled flat. If the engine didn't have to have the engine mounts swapped side to side(Z-18et) then it would have fit perfectly, but now it fouls on the engine mount. It's going to be dick all work to fix it, but then I'll have to get the flange that bolts to the engine re-milled which = more $$$$$$$$$$$$. But hey, you learn from these expenses, sorry experiences.
