dont put the 2.2 heads on the 2.5 in any car you want to last any amount of time

the 2.2 and 2.5 are interchangeable

That should work from what I've read/heard but I have never tried it myself. I know phase II stuff is pretty much plug and play and that the IM will bolt right up.

it will drop right in place. Just use your intake manifold and wiring and you'll be fine IF you are using a single port ej22 from a 99+ (it might be 98, i can't remember). The valve covers should look the same as your 2.5 and have no writing on them.

You will need to swap to the single port header as well.

be warned, it will be VERY slow.

Like I said it should be a direct swap. If you're worried about it, pull the covers off and you can see the crank pulley. If the crank pulley is different then its a good chance the cam is also different. And if they are different, it will be really obvious. The difference in crank pulleys is one has something like 8 teeth while the other style has something like 18.

Like I was saying though, should drop right in. I went the other way in mine. Ej25 from an 03 swapped with my 99 ej22.

I put the ej25 phase 2 from a 2001 automatic outback into a ej22 phase 2 1999 legacy manual. Retained intake. Had to change both cam and crank sensing wheels. Not a big deal but definitely they where different. Also had to change the exhaust manifold Y-pipe. Obviously, I had to swap flywheel too due to the transmission differences. I disagree about the power comments on the 22 vs 25. The 22 is slower but not by a lot. Plus fuel economy is around 27mpg average on ej22, and 25mpg on ej25. Other probelm is the computer is delivering fuel for an ej22 for the ej25 engine so there are some minor idle issues, and somethimes throttle jerking due to slightly lean mix and computer trying to make adjustments. These are MAP engines not MAF. If they were MAF I wouldn't expect an issue.
