costs penuts if keeping enigine standard, what litre si do you have? if zetec use the exhaust manifold of it, sump and pick up and then all you need is a smaller oil filter on the mondeo pump, then a "deep, desk OR dewy ecu, mass sensor, throttle bosy and injectors otherwise is pointless".
my 2.0 in my old one cost me £70 from breakers, plus new sump gasket and few bits, shouldnt look over a £100 in parts if not having a rebuild
