Why would you want to do it mate? think you will need like you say mounts, wiring loom,etc.

best bet would be to buy a 1.6 16v escort that is rotted/scrap but running well so you have all the bits but personally think it is an odd choice.

Most stick a 2.0l engine in, maybe even look for a mk4 escort that has been done and create a rep rather than convert yours??
