Bollocks! No disrespect. The ST170 engine is a Focus s3 zetec block with a nicer head on it.
It'll mount in without too much trouble Neil, same gearbox pattern and the engine mount is the same as the earlier Zetec/ZVHs, 2 bolts line up as standard, mod the mount for the others.
It's been done yep, the engine in Jamsport's car is an ST170 one, I recall another person doing it aswell...
