On lad has fitted a focus ST engine, it was the tightest fit i've ever seen but its possible.

I'd say go ahead with it if it means that much to you, but go with caution in the way that it might not be straight forward. One lad on here ended up scraping his car off because the car was that fuckedup after the conversion, he went and bought an st500.

If you fancy an engine swap and have the expertise around you then go for something bigger than the 2.0

Its a big job and don't cut corners anywhere, go for it

Would be nice to run a mk1 rs engine but there like rocking horse **** and i dont want to spend that much on an engine on its own. Theres a few for around the 1500 mark. Plus ive always wanted an st an you can get parts fairly easy. The rs route is avit more tricky lol

Ive got the mechanical knowledge. Just get worried where i got to cut into things cus i worry about if its strong enough etc. hense why i want to go down the st route as its a fairly "straight" swap..i use that term loosely.

There's someone on fiesta mk6 classifieds on Facebook thay was selling a zetec turbo engine that they had in there mk5 zs. Don't know if its still available or any good or not

You can get the 2.3 crate motor cheaper than £1500

You could always go the mountune route and get there 2.5duratec race engine that fits anywhere where there is a 2ltr but it's an expensive engine

This would be awesome

I have seen a mk7 fez with a 2.0 ecoboost motor

Stop pissing about, do a rear engined, MK2 4wd conversion

£20,000 later

Im looking forward to someone doing this reckon i wouldve thought about it had they released before id started on their other mk6 kits

Mountune also mention a Duratec Turbo on their race engines page.

So I guess they could fit a turbo to your Zetec S if you wanted to go down that route.
