well in that case, there have been a great many topic on this forum that indicate what u have been talking about, there have been conversions from the 3SGTE to a twin turbo V-6 plus I believe that many people have done some benchmark tuning on a possible supra tt engine swap, (not too sure on this one) plus u might consider that some of the older mr2's have had V-8 transplants... I know that there is a quick google search for u that contains an 80's mr2 with a northstar engine transplant, and many other people that have done similar... I can give u a link... but in my opinion, this car is a joke... this is a peice of crap mr2 with this giant engine in it... and it looks like hell, but it does eventually run..
Good luck finding a forum that suports your request... let us know what u find
here is the link ...

Eventually, the car does get a paint job, and doesn't look too bad... but in my opinion... these cars weren't designed nor were they ever meant to have V-8's put in them.. they are after all a foreign make, cornering car... but whatever, they did the same thing to the Fiero... at least thats American, and has the american motor in it... But HEY... it's different right, lmao
