In the MK2 (1st zetec we fitted) we used 2.0 mondeo engine with std mondeo clutch and pressure plate, machined the ring gear stop 13mm further forward to use std escort starter, worked great but old type starters wear out the bendix clutch (starter motor clutch not transmission clutch) and need replacment every 12-15mths or so.
we have since fitted a 1.8 flywheel,machined to take pinto pressure plate (1.8 is smaller and lighter than 2.0 and has a smaller clutch which simply slips above 2000 rpm). the lighter flywheel makes for a much more responsive engine, and std pinto clutch works well. the starter to suit this is from a scorpio/sierra and is available from woods auto electricail in Halifax UK who will post to Australia ( i will look up the part number and let you know).
I have drawings of engine mount brackets for zetec to chassis mount which I can dig out and post if you need them.
I have used Retro sumps engine mounts and water rail and raceline water rail, they all work well. The raceline rail is slightly better looking. I will dig out a couple of happy snaps of the 2 fitted so you can see.
