basically all you need engine wise is the 2.0l block and head.
then you strip all parts off the escort block and head and swap them over including all pumps/ brackets/ covers flywheel.
220mm flywheel on your car the same as rst's.
the 240mm mondeo one only fits in the mtx bot which is shit gearbox, too notchy.
as for inlet manifold, if you have the alloy item you will need the 130 spec manifold with HO stamped on it and throttle body.
if you have the plastic one you will need the 1.8 inlet with 2.0l throttle
