I have a 99 2.2 phase 2 motor in an Impreza OB sport that threw a rod out the block. I have a 94 legacy 2.2 motor that I was goimg to swap in untill I started learning the differences between the two. now my question is, can I put the heads and intake on the older block? will there be piston to valve problems? Any help here would be great as i would like to get this done soon.
