I've searched and couldn't find the exact measurements for the Type-S Pistons (oversize).
Does anyone know what the exact finished cylinder bore size (for oversize) along with the
ring groove widths and depths measurements?

I ask because I'm trying to purchase new piston rings made by TotalSeal. Has anyone ever used their products in their H22's?

-Thanks in advance

 

bore sizes?

A = 86.990-87.003
B = 86.980-86.993
OS = 87.260

got that from the prelude essential links.....

 

whats up with the a and b pistons? i keep seein that but i don't kno what the difference is for

The diff. is for the variation in the frm diameter. Honda is a stickler for tolerances.

 

do you know if the standard size and the OS pistons use the same piston rings or are they different sized rings?

 

also can you run all a's or all b's?

 

Ok, how about the ring groove widths and depths?

depends on what is stamped on your motor.

You can run all A's (with a little honing of a B hole if needed), you can run all B's if you have all B holes, but not if you have mixed holes eg ABAB, AABB etc. For mixed holes you need the right sizes or you can run all A's.
