no one has done it yet to my knowledge. the cradle and mounts are 'similar' but not a straight fit(different shell) if your handy on the tools and fab work it shouldnt be an issue. it just came across in the first few posts that you didnt have a clue but after reading your reply it says a different story.
as for 300bhp i thought you were on about the st3. i haven't done the conversion but have looked into this engine(and i have a st2 and a mk1 focus) for a different conversion/application and there is no prefabbed mounts available just a case of suck it and see mate.loom might be a pain too.

also you talk of dealer servicing...your gonna do a conversion like this and not service it yourself???

ag and reyland change them to cossie power i would doubt they have done this conv.
