An engine and tranny out of a 2004 forester fit in a 2005 legacy sedan? What needs to be changed, according to a salvage yard the engines in these cars fit only the 2004 and the 2005.

The engines should be the same. You might have to swap a few sensors and the trannies should be the same too, but of that I am not certain.

should be the same motor and tranny... just make sure that your ratios are the same between the diff and the trans.

according to a salvage yard the engines in these cars fit only the 2004 and the 2005.

keep in mind salvages yards HAVE NO IDEA what interchanges and what does not in general. so what they say isn't really worth much at all for Subaru specific questions like this. all they do is read whatever the junkyard database tells them, they might act like it is fact but it might be wrong, it might be right.

 

that being said, i don't know but i would suspect they're interchangeable. this newer stuff is hard to tell, it's expensive, not a lot of junk and cheap cars floating around yet and folks haven't played with them enough to learn what interchanges and what doesn't.

 

when switching models/years you also want to make sure the final drive ratios match with the trans. you can still use it, but have to match the rear diff if it's different.
