If I'm not mistaken the stock size is 81mm, but the next size up oem pistons are 81.25? So I think you *might* need 81.1mm which I dont think exists, but I'm sure I'm wrong.

I would just get some 81.5mm type r pistons and have it bored and honed at a shop and call it a day.

if a machine shop hot tanked the block and bored it i highly dout they only bored .1. I would bring it to a local mhop and have them mic it. if it is only .1 over it will be cheeper to have them go .25 over, or have custom pistons made.

assuming it's .1mm not .1" (2.5mm) you still have the option of going to .25 ov.
take it to a shop get it checked and rebored.
