hi guys just wanted to no if a focus st engine will fit a fiesta st and has it been done before and if so can u send me links

 

There was one on ebay a few months back, some mechanic managed to squeeze one in with only a few mm to spare either side of the engine, was a bit of a lash up as well but it ran!

Sadly no links !

 

im sure i seen one in ford fair last year an it looked a real tight squeeze as you can imagine BUT from what i remember(dont quote me) it looked like the lower arms had been modified an not the best either why i dont know... but 90% sure i seen it an it was for sale too

 

ST170: 4 sure.
ST2.5: might be a tight job. 5 inline + gearbox...

 

Have you thought about trying the 2.3 Duratec thats in the mazda 3 mps?
