you need:
Manifold, either a RWD 4age one, or a converted FWD one
Water pump and outlet pipes, i think that the ones off of a 4ac fits on.
you also need a crossmember, and gearbox for a ke70 i think. get ones from an AE71.
throttle cable
fuel pump/surge tank
altenator brackets
exhaust manifold
that's nearly everything... probably forgotton something though.
