NOT dyno numbers but...

i have a set of jdm PCT pistons in OS. [.25] over and on the box
the numbers are "13020-PCT-000"

my question , what would the numbers be if they were stock bore? i couldnt find this info when i searched!

thanks

edit: i assume they are 13021-PCT-000, BUT i again am not sure. can anyone verify this?

 

bump, i know someone has these in stock bore.

 

stock bore is 13010-PCT-000.

 

awesome! thank you sir
