"jimfoo"j ust looking for a quick clarification. 81mm is the stock size for the 2.5 tdi pistons or the 1.9.... I thought 80mm was the stock size for the 1.9 pistons, am I wrong. I'm assuming the 1 over is a 81mm piston, is there any such thing as a 82, 83, or even a 84 mm piston. I mean a mm isn't that much so It seems to me on a worn engine... or one with damage may need bored 2,3,or even 4 mm over stock (ok maybe 4 is pushing it). But still it seems odd to me that 1mm over is the largest size I could find. I look into those 2.5 pistons.... and see what I come up with.
