Hi Everyone!! Im looking for the min and max clearance cylinder to bore , I've had my piston skirts Teflon coated and want to check that there is still enough clearance, they basically apply the coating and then it's down to me to ensure they are down to correct size buffing down the coating. I'm sure someone knows, I idd get a general sizing from someone of 3 thou per inch diameter of cylinder bore but I've got a feeling it will be tighter on the Porsche. Any help much appreciated!! Thanks !!!!!
