2l silver top zetec is what you what, only available in a mk1 mondeo, youll need a 1.8 or 1.6 inlet, sump and some other bits i think....!? (again all silver top parts, but the 1.8 and 1.6 parts can be found in a mk3 fiesta, mk 5/6 escort (i think!? ) and mk1 mondeo

theyll be a few threads on here about it but if your not sure get another one up, fast ford did a feature on this very conversion in one magazine, if you could track down a copy, or it might be on there website, it would be a big help for you i think
