There is a ej22 manual here somewhere, maybe you could dig it up there.

I can tell you from personal experience that you can bore it to 99.5, and drop in a 2.5 phase 1 crank. I run 23 psi all the time. It's on 111 leaded, in a sandrail, but on boost almost all the time. Mine ran for three seasons before I had to sleeve it due to some fuel shortage issues.

Sucks that with 9mm~ish wall thickness, and 113mm bore spacing, Subaru still went with siamese'd cylinders. It'd be nice to have a little coolant flow between them for det. resistance.

another reason I went with my phase 2 cobb block...(fully closed deck...but still retains most of the ej25 coolant passages ...but I sleeved it anyway

yeah, but it does get a pretty good job of getting the passage in the crack to cool the wall.
I'm glad they did make it siamese leaving more room for bore...especially as we have such little stroke.
