You will need the trans from the 1992-95 due to the thicker back plate. I would go with the TII motor/trans. It is cheaper overall.

Go to the 1st-gen section - there are a couple stickied articles on T2 engine swaps.

Why bother with the REW engine? It sucks... if you care about power you'll be throwing the stock turbos away for a signle anyway.

Also beware that "1992" technically means FC in the US, not FD.

Go with the TII it won't break you like the REW will and you don't have to deal with the million vacume lines and tubes and carp. the TII easier and less fiddling with stuff you don't need.
