hi, i put a focus M45 jackson racing supercharger kit on my 2.0 mondeo zetec silvertop (which is year 1994). the differences where the alternator, PAS pump and entire drivebelt route/pulleys is totally different setup, totally different engine mounts, sump/oilpan has the recess in different place, exhaust downpipe and cat totally different, IAC valve, throttle body and throttle cable all different. as is the traction control and cruise control units. cambelt is shorter on the silvertop.
also the fuel rail and injectors, fuel pressure regulator, MAF is 6-pin instead of 4pin (easy to convert though), then theres the internal differences like hydraulic tappets on the silvertop.
the cams and cam gears are interchangable, as is the inlet manifold but you may need to mod it around the alternator.
i can go into more detail if you need it just giz a shout.
