alrite,
the engine will fit straight into ur escort an mount to the original gearbox, u can use the fiesta rst ofab ecu an engine loom, escort rst exhaust manifold but ull have to tap new holes into the zetec head, a T2 or escort rst T3 wouldnt really create enough boost pressure for the 2.0 so a cossie T3 or T34 would be needed, the cossie turbo will fit the manilfold but u will need to adapt the elbow for the exhaust to fit.
