Sleeving is only if you are going to run more than 25psi boost on a 2.5 according to perfourmance (who built my short motor and supply the parts for most 2.2L's runnign around including WRX STI's).

I voted for a 2.2L. Fully closed decked very strong but with a few extra CC's to drive a big turbo. Perfect balance between Rev's and ability to run higher boost.
