3.0 TT, so I assume you're talking about the MKIV (last generation Supra)? I'll move this to the right forum; You'll get more response.
My opinion on swaps is to avoid them if at all possible. There will always be things you are missing and it is seldom as "straight forward" as you would like. If you do opt for a swap try to get a vehicle that is as closely equipped as possible so you don't find yourself later spending a furtune upgrading other items such as an anemic N/A brake and suspension setup or installing an oil cooling circuit which didn't come in your car but did with the turbo model.... and so on.
Del Sols have driven me nuts.... Should have been mid/rear engine, RWD... and well, in the all to common opinion of MR-2 owners (especially the SW-20 crowd), much sexier.
Anyway, welcome aboard and I hope you find something that suits and serves you well!
