Hi was just wondering if a st225 engine would fit in a mk 4 fiesta ?? Ive just stripped mine out and looking for a engine to make it fun

 

Most common swap is to the 1.7 puma engine after that the 2.0 blacktop focus conversion although i have seen RS2K engines and RST engines fitted these require a lot more work with custom fabrications for mounts etc.

1.7 is 123bhp bolt in no mods. So is all the work needed when you can bolt in 50bhp?

But if the budget is there you can get anything in there with a lot of work.
