Since the 2.0's not available to look at yet as far as the specific changes versus the Forester's 2.5l I figured I'd go ahead and ask if anyone has any inside info on the overall differences between the two blocks.

It'll be interesting as far as normally aspirated engines to know if we'll be able to get away with a FB25 part swap on the FB20 to gain a little displacement and still maybe pass Smog out here in California.
