I've been thinking about doing this for a long time now, the wheel bases aren't that short only 100mm less than an E30 or an ma70. I think most have gone mid-engined for ease, and thats where the problem lies. My intention is to get an ma70, lop the body off, shorten the floor and prop by 100mm, stretch my Jetta over it and get a plate to mount my R lump onto the Supra Gearbox. Bish bash bosh, a few mounts here and there and off you go! lol obviously it's a hell of alot of work, but I really can't see the down side, supra brakes/suspension/chassis my lump and body.
