That's one I haven't heard before......, I suppose you want to do a rear seat delete and a L. hand driver install as well. Some one will know if that can be done or not. You may be better off going with just an n/a 7mge if it can be done because it's smaller.
The 7M-GTE can and has been shoe-horned in the MKII. I don't know all the specifics though.
I'd try getting ahold of Rob with 935Motorsports he's in the middle of swapping in a 7M-GE and should be able to give you the bulk of info you'll need. His 7M-GE is out of a Cressida, given that their sump is closer to center it may fit without much work (if any).
