just did the 2.5 to 2.2 engine swap in my 96 outback. this was the easiest damn engine swap ive ever done. it was almost a complete plug an play. the only things i changed were the bracket that held on my a/c compressor and and the fly wheel. i used an engine from a 95 legacy sedan with an auto tranny. the engine had 73k miles on it and i got it for 300 bucks on CL. other posts have talked about problems with the power steering lines, if you just disconect them down buy the cross memeber instead of at the pump there is no issuse. car runs great i get 25 mpg in town and 30+ on the highway, probaby would be a little better if i had a lighter foot. as for power loss as far as i can tell doesnt exist. i raced my friend in her 98 forrester from 0 to 75 and it was for argument sakes even the whole way. took it DEQ after wards to get new tags they pluged into it and it went right through with no problems. car runs and drives great and im alot happier with this engine that seems to be bullet proof then the pos 2.5 that was in it. I know there are other issues with different year engines but the 95 droped right in and only took me a few hours to pull the old motor change those couple things and drop the new one in. can answer any questions any one has regarding this swap. And if any one that lives in portland Oregon is looking for a car or knoww some one who is this one is for sale, and the whole car is super clean and super straight. $6000 obo:headbang::horse:

You don't have a 2.2 DOHC unless someone bolted DOHC heads onto a 2.2. They don't come from the factory like that except in the 22B...
That car has the phase2 engine/electrics so you'd need a phase2 ej22 to swap in.

Do the "newer 2.2 w/EGR" swap that the fella that started this thread was talking about.
95-99 WITH EGR.
95 2.2 auto (with EGR) is the first choice mostly due to the Y-pipe.

Do some research here. Lots of info.

I like phase II 2.5's. They're reliable and powerful. What did you "blow" on it?

He can't swap a phase2 ej25 into it though without a stupid amount of work.

The '00 Outbacks have EJ251 SOHC from factory. It would not be a swap, so yes he could put the EJ25 SOHC Phase II into his '00 Outback. The opposite is true in that you can't put any Phase I EJ25 into it, you wouldn't want to anwayz its a terrible engine.

Oops, I didn't notice the thread jack and thought the OP wanted a phase2 in his 96.

Auto and manual engines are the same, so yes. Either will work. I believe the phase2 all had EGR, so that's not an issue.

Before dropping it, do a reseal and timing belt. No need for new head bolts, people don't replace them and do fine. Subaru head gaskets only!!!!
Subaru thermostat, and replace all other gaskets and seals while you have the motor out. Do the timing belt, all idlers and new tensioner. While you have it off good time to do crank and cam seals. Reseal the rear separator plate, but DON'T do the rear main seal if it isn't leaking.

If the rod came loose I doubt it was the knock sensor that cut the motor. It was probably the rod going through the block or something that cut the motor...

Mounts are optional, water pump if you must make sure it goes forever.. You might also want to do crank and cam seals.

IMHO, i would just slap it in with new timing (make sure u get the idlers and tensioner), and a new set of plugs if there is nothing wrong with it.. Check for oil and antifreeze around head gaskets/valve covers. Check around the cam shafts when you do the timing to make sure u dont need cam seals. Then i'd just run it. It might last you 20,000 or it might last you 200,000, but I've seen people spend loads of money doing all the gaskets and seals, and they throw a bearing a month later. If you want a new motor, buy one or do a rebuild, otherwise these motors are pretty cheap to buy and very easy to install. If you're paying too much for the swaps, find a cheaper more honest mechanic.

Other option is the '02 engine, which I have no clue if you can use it or not (i think you can, but i wouldn't take my word for it). The only issues i know of going between auto and manual is the flywheel, and sometimes theres a belt guide for the timing belt on the manuals. Somebody will have to elaborate on this swap, but i think it would be your best bet. I wouldn't go spending loads of time and money on that old engine, as I've seen them go 300,000 no problem.:cool:

I just did a simaler conversion on my 97, everything seemed to work fine, BUT the check engine light has been on since the install. Once the car warms up it bogs terribly at low rpm and gets terrible gas mileage. Any ideas.
