83-86 7.5 in rear end, t3 turbo, non intercooled, e3(crack prone manifold)
87-88 hood scoops, crappy I/C setup, IHI turbo, better manifold, head design, 8.8 with rear disc brakes etc.

all verry fun, easy to work on, have potential, just like it was said they are heavy. I've worked on my share of 2.3ts from stangs, merkurs and pintos etc.
