which would be the better, more cost effective engine to put into a 1986.5 supra?

7M-GTE?
1JZ-GTE?
2JZ-GTE?


My car looks like the one in the pic.

Hmm if it's a 86.5 you'll be best off putting in the 7m GTE b/c if you wanted to go 1 or 2jz you'd have to do a lot of fuckin around with the motor mounts and cross members and crap, unless you like doing work get the 1jz don't bother with a 2jz wayyyyyy to expensive to get workin right and 1jz will make some pretty decent numbers as will the 7m being the cheapest of the three.
