in the 90s the ej22 and the ej25 are different. they may look the same, but they are a different size/shape/contour. this is a fact.
in the 00s the phase 2 ej25 and the phase 2 ej22 are the same size and will bolt on the other block. regardless of how different they may look the block dimension are the same and the mating surfaces are the same. this i have heard from reliable sources.
edit: im not familiar with the 00 ej22 but the 00 - 01 ej25 do not have EGR.
