There really aren't any. Be sure you get the correct four exhaust port 2.2 motor with EGR, complete with intake manifold and all that jazz. You have to reconfigure a few hoses to prevent a CEL from coming on due to the lack of an underhood charcoal canister in the 2.5 cars. On some vehicles, you have to mix and match brackets for the A/C compressor. The power steering hoses don't line up with the support brackets (I just blew this off & let them float free...they don't really seem to need all that much extra bracing.) Make sure you don't clobber the torque converter when reinstalling the engine. (Mine is a stick, so I can't help with A/T advice beyond that.) Good luck!

best bet is find a 95 2.2 and it doesnt get any easier, if you get a later motor get the exhaust manifold with it due to the single and dual port change.

Going to make this simple for you as I have done the 2.5 to 2.2 on a Legacy Outback. I used a 97 2.2.

 

From the donor car (450 dollars tops)

 

1) Engine / use the exhaust manifold from the 2.2 donor

2) AC Compressor you must keep and hoses from your 2.5 mount onto the 2.2

3) Metal Power steering lines from the 2.5 move them over

4) The fly-wheel from the 2.5 will have to be moved over to the 2.2.

2) new o-rings for the AC hoses you disconnect

3) new o-rings for the power steering lines you disconnect

 

From Walmart

While you are at it replace this on the 2.2 donor (100 bucks) an easy to do with the engine out.
