Thank you for posting this. i was looking at the Aussiespeed manifold to se if it would clear the SPA turbo set up and the answer is no. I think if you mounted the turbo direct to the manifold it would have even more fitment issues. So it looks like to get a better intake fit the flange needs to be milled at an angle or an angled adapter fabricated.

How do you like the FITech injection? I've heard they can have fuel distribution problems on the L6. I would think that it would want to overfuel a 250.
