I did some searching here and on nabisco and didn't really come up with what I wanted so.... I'm looking at an EJ25 SOHC core motor, what major identifying features are there so I can tell which model it is? I'm hoping it could be a donor shortblock for a frankenmotor. Thanks!

Timing cover has 2 round impressions vs four.

The engine is a SOHC, I just don't know how to determine what generation.

there were no SOHC EJ25's prior to 2000 (excluding the intro's in a few 99 models). do you have a reason to believe this could be newer than 2004? my guess is it's a 1999-2004 Phase II EJ25. seems like there should be some info on the motor, either inferred or positively?

I did get a number off of it (serial # maybe?) by the bellhousing flange B561869 if that means anything to anyone. I will probably pick it up in the next few days and see if I can get any details on it's history. I think it was a take out from a local shop that ended up in the boneyard where I found it.

hmm abe, no clue about those numbers.

 

i haven't worked on a 2005+ yet so i'm not sure what the differences may be. cars101.com has lots of subaru specific info and specifies changes, whether any would be useful in showing a 2005+ block over the earlier 2000-2004's I don't know, but that's where i'd start if i had nothing else to go on.

 

at some point the exhaust "came forward" so to speak, my in-laws 2009 EJ25 is like that, so that would tell you it's not a 2000-2004 if it still has the manifold with it.

 

or ebay pictures?

 

i think subaru360 and some others here have some later engine experience, maybe they'll chime in.
