Re: bored to use sti pistons?

Also FYI, cosmetic makes a head gasket for 100mm and 102mm bores. Just be careful, the eg33 cylinder walls are already pretty thin, so I wouldn't try and go past the OEM STi 99.5 bore. If you go that route there are lots of good aftermarket pistons available.

The only thing I'm not sure about is the piston pin height between the 2.2 (svx size) and 2.5 liter pistons. You would also need to confirm the valve reliefs to maintain non interference status.
