Some interesting content in
this discussion. A quick discussions re: a 2.5 swap from a Ford Fusion into a Fiesta.
Post #16 is of interest. "We have installed a 2.3l (same as the 2.5l) into our Fiesta. It fits fine. No possibility of using the stock
ECU. If you use the Focus (pre 2012) transmission, us can use the Focus axles. They fit into the Fiesta knuckles...". The 2.3 they talk of is the DISI motor - Direct Injection and twin VCT. Not applicable here on the standard 2.5 as we've discussed. But it's the 2nd time I've seen reference to using the Focus MKII driveshafts on the Focus MTX75 gearbox fitting the Fiesta knuckles.
