Patshnish Posted March 9, 2017 Share Posted March 9, 2017 (edited) I am new to this forum as of today so I apologize if my format is terrible but I have a question concerning what engine I could put in my Outback. I threw a rod through my engine block and a local business is parting out a 2002 Forester 5-speed (my Outback is automatic). I don't know specifically what engine is in the vehicle but would whatever is in it fit my 2001 Outback? I currently have a EJ 251 I believe. Attached is the engine i'm looking at purchasing.

AdventureSubaru Posted March 9, 2017 Share Posted March 9, 2017 (edited) yes. The 2002 forester engine will fit just fine. You remove the flywheel from the motor with the manual trans and bolt the flexplate from your motor to it. Swap the drivers side cam pulley and the crank sprocket over to the new motor so they match the ECU in your car. (This is good practice for ANY replacement motor on subarus of these years) Good time for new timing belt kit since it needs to come off anyway. Double check the sensors on your car to the forester. It may be MAF instead of MAP. If they are different, just keep the intake manifold/wiring from your car. (A long block swap) Edited March 9, 2017 by AdventureSubaru Quote Link to comment Share on other sites More sharing options...

I don't know if you could tell what the engine I attached is but it looks a little different than my current engine I am looking to replace.

AdventureSubaru Posted March 9, 2017 Share Posted March 9, 2017 What differences are you noticing? Both 2001 outback and the 2002 forester had the EJ25 SOHC motor. The attached image looks like the EJ25 for sure unless someone swapped an EJ22 or EJ20 in there previously. Quote Link to comment Share on other sites More sharing options...

First off I should mention i'm not personally very good with cars but I just noticed the difference and its the intake for the air filter on my Outback is different. But after realizing that i'm certain its the same engine, aside from the stuff you mentioned about the manual hookups.

AdventureSubaru Posted March 10, 2017 Share Posted March 10, 2017 Yeah. You'd do fine with that motor. Depending on the history of it. Look up what to look for - mostly external head gasket leaks (some weeping is normal) Compare prices on car-part.com I have a writeup on here for a complete remove and reinstall of an EJ motor. takes about a day on average to drop one in.

If you could link the write up that'd be appreciated! Here is the link for the ad for the motor in case you can derive anything more helpful from it: https://seattle.craigslist.org/oly/pts/6007691247.html Quote Link to comment Share on other sites More sharing options...
AdventureSubaru Posted March 10, 2017 Share Posted March 10, 2017 http://www.ultimatesubaru.org/forum/topic/159902-1990-2004-ej18-ej22-ej25-diy-complete-engine-remove-and-reinstall-guide/?do=findComment&comment=1351416 Here you go. This was an earlier ej motor so you'll have 8 bolts on the bellhoising instead of 4. Different air box too. Otherwise about identical. The motor already has a failing head gasket. Ensure that it has not been overheated. Diy head gasket job is about 400 in parts and cost for a machine shop to resurface the heads. I'd look into car-part.com and see if there's a better option nearby. Check with a want ad on here too. Quote Link to comment Share on other sites More sharing options...
