Downsides - 2.5 intake manifold is set up for the EGR system. You will have to seal that up to run on a 2.2 block. The previous owner of my 2.5 had done that, and after using it on his 2.2 for a while switched it back to the 2.5 I have. Which means I can't replace the EGR. I think they are ported about the same, so besides giving yourself some trouble I don't believe there would be any real difference.
