engine mounts, trans mount, anything thats on the 2.3 engine thats not compatible with the 2.5

and the year of best fit of the fusion

Yes, the Fusion 2.5 is basically the same engine as the Gen 1 Mazda3's 2.3; just a heck of a lot more reliable, more powerful, and similar fuel economy. The Duratec 2.5 swap is a VERY popular engine for Gen 1 Mazda3s with blown 2.3 liter motors, it is almost a straight bolt in; if you do a search you can find some very detailed threads available on some Mazda related forums which will take you step-by-step through the conversion process.

The results are so good I've actually toyed with looking for a clean 2008 or 2009 Mazda3 s GT 4-Door with a blown 2.3 and doing the conversion myself, just for the heck of it.

what year fusion is the best fit?

It's best if you use a search to find one of the How-To threads; they'll present you with lots of options.
