ok so if I have 4 pistons with the "B" stamp.

on the case I am going to use I have 3 "B" stamps and one "C" stamp.

I dont have acess to a mic to measure the differnce in size yet.
does any one know how much the sizing will be off?

I sliped the piston in both the B and C holes and cannot see or feel much differance.

I know I need to do some actual measurements.

this is on an EA82T motor.

The letters don't mean much unless you are trying to upsize to avert a problem.

Put a piston in a hole. Use a feeler gauge to measure fit. Subaru allows .003 clearance. If it's tight or loose in that cylinder, try fitting into a different one...chances are it will fit.

Thanks Emily;)
measured at the skirt of the piston I would assume?

No, with the top of the piston toward you, as it would be naturally.
