DO IT!! After driving my mates AE86 with 4AGZE I fell in love with them, they are just so controllable. I recommend getting an SC14 Toyota charger. It has its own sump and is mounted like an alternator so you can have it on the other side. You will pick one up for around $400 (Sprintex twin screws around $2400...). The other great thing about them is, they have an electric clutch,so you can set them up to be switched off with a switch, or if you have electronic ignition you can set them up to come on with the throttle etc.
