Piston decision.....

[jdmfreak]

I know that the Probe forged pistons are slightly over stock size (something like .006") for a "hone to fit" sizing. The rest all were at 0.5mm (0.020") over.

So they will be the same size as my "stock" 20 over pistons? Do they all call for tighter clearences?

It depends, I guess.

My .020 Arias pistons called for an 83.49mm bore.
