piston sizing issue

Featured Replies

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.

bumpin:-\ come on anyone have a clue what I am talking about?

 

guess all the brain power has drifted away from here.

Someone with an EA82 FSM is going to neet to answer that one for you.

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.
