Is it possible to use Z31 pistons in an SR20? I know the Z32's will fit with a little modification, but what about the Z31's? Would it work and have lower compression? Is it just plain impossible?

I guess it would depend on the bore. The Z32 pistons require a .020 overbore making it 86.5mm IIRC and they need some modification to the rod end to fit the piston properly. NA Z32 pistion will give you around 11:1 CR and turbo pistons will net you a 9:1 CR.
