just get the ecu from a non PATS mondeo 2.0 and it'll run properly. a 1.6 ecu will be miles out.

you'll need an escort water pump, sump and oil pickup. use your existing inlet and exhaust manifolds, alternator etc. then use a 105spec 1800 flywheel and clutch, put the 2litre injectors in your 1.8 inlet, plug in the 2 litre ecu and fire it up.
