They seemed satisfied with the wall thickness for a N/A application. I can't comment since I don't know the actual wall thickness myself.

A couple of days ago I was talking to "Mike", my local machinest, and we were looking at Sov13t's block.
He measured the factory sleeve wall thickness at about 0.160", and as I remember we thought that we could bore the cylinder out to 100mm to match popular pistons, and available head gaskets.
The aluminum casting surounding the sleeve is about 0.250" thick.
He thought that that was a safe overbore if it was not supecharged, or turbocharged, but untill someone does it this is all just speculation.
