you'll struggle to find any decent mk4/5 2.0 conversion guides or answers... as they all vary.

A lad on facebook used to make the mounts for said engine swap, his name was jordan cartwright i believe, could give him a message see if anything can be done...he owned a blue mk5 zs with a 2.1 zetec turbo lump in it.

Or you could make a template out of the mount you need with some card, and take it to a metal work place to get made in metal.
