ATP do at stock position 35R. I can't remember the exact sizing, but I'm sure the housing and wheel sizes aren't much different from a T3 flanged 35. Going from what I have, I'm pretty confident that anything over TD06 sizing, begins to foul on the heads.

Saying that a 3071 or a 3076 would be a nice size, keeping it ball bearing. Are you maintaining the stock engine bay look of the TMIC? If so you would be pushing the efficiency on the TMIC & realistically there would be no point in installing anything larger than a 20G & even that would be a push I believe. I guess it depends what you want from the car though.
