Personally I think it's just a matter of flow. The 2.5 could be a screamer, but the 8 valve heads barely flow enough for a 2.2. My car came with a 2.5, and I'm out of money so I'll just keep short shifting and enjoying the torque. :-)

Believe it or not I think it may actually be more crucial for a smaller displacement motor to have a well breathing cylinder head that one that is larger (when comparing the two).....reason being is the smaller motor has the mechanical ability to turn more RPM....it just needs the flow/volume to do so. The larger displacement motor cannot turn as high a RPM as the smaller motor but yet pumps more air early due to the increased cylinder volume.......well within the flow ability of our pathetic heads as it is at such a low RPM.....this is where the excellent torque numbers on a 2.5 come from. IMO the 2.5 is the best warmed over stock motor between the two....it's displacement works well with the flow characteristics of a stock type head.
