Yes the 2.5 will defo fit so long as you have all the bits.
I would say it is going to be easiest cheapest to get a damaged one and then side by side swap over eveything you need.
The other alternative is the 2L zetec and tune it a bit, but ecu will become limiting factor.
If you were up for changing ecu to aftermarket power would be no problem keep a zetec on throttle bodies 200bhp is easy with other mods, on a 2L.
