get ab ae85 crossmember, and an early (read: bigport) 4agze, and some RWD 4age mounts, a RWD blurtop manifold, ditch the supercharger, get a turbs manifold off the dude on toyspeed that makes them, run a T28 ball bearing turbo, link ECU, and go make mega horsepower.
done
alternatively, a smallport (ae101) MAP 4agze, and do a "cut and shit" inlet manifold to get the throttle body on the right end.
4agze with a turbo running 5psi makes more power than one running a supercharger on 8-10psi
true story.....
