I've got an '07 Forester with a healthy engine, just a little over 100K miles on the car but a bad trans, rust, a loose balljoint, leaking A/C, etc, so I'm going to part it out.  I'm assuming that engine will fit OK in a 2009 or 2010 forester? Just want to confirm with the more experienced minds on the forum. 

To be more specific, both vehicles in question are N.A, not turbos. Looks like some of the JDM engine suppliers are claiming the same engine will fit all these cars (if the intake manifold matching the car is swapped over) so that implies that everything is interchangeable. Someone on here HAS to have done this though, would really appreciate confirmation (or not) that this will work.   In the past I did an EJ22 swap into a '98 Outback which seemed like much more of a stretch at the time....

 

 

the block should work fine, swap intakes to keep the matching wiring harness.. altho, i am hardly an expert on this topic.

you are talking 2 different generations... the 07 in one, the 09-10 in another. so there are bound to be some differences.
