fair play to ya mate, sounds like its gonna be minty fresh! theres alot of info on the net for a zetec conversion.... inner wing engine mount needs modding, alternator and bracket needs to be cvh (change pulley tho).... exhaust will need mating up at bulkhead area..... just basics to think about.
wiring wise make sure u get non PATS engine and loom n ecu, makes life easier! make a fuel pump relay loom up, wiring in the loom is pretty easy even i managed it (under supervision lol) just google it and ul find the diagram to follow.

u got any pics for us??? open a photobucket account, upload em from ther n its easy to get em on here then!!
