Dont mean to thread crash you here but I have a question for you about these pistons. I tried buying them and is confused because there are two types. standard A and standard B. How do I know which ones to get ?

no worries bro, thats why we have forums... A type pistons are standard size which are 87.00 mm bore and the B type pistons are 87.25 which are oversized. if your block has never been honed and bored over you need the standard size with are 87mm

You sure this is true? IDTS.

Look on the block, it will say "AABA", "BBAB" or something similar to that, whatever letter order they're in, that's what pistons you get, A or B. A & B are both standard 87mm.

If you get oversized TSX pistons, they're 87.25. In this case, the A or B letter configuration wouldn't matter.

This link will show you A & B are both standard 87mm and .25mm oversized is different altogether.

Thanks!!! I tried looking for the code but was not able to. Problem is the motor is still in the car and assuming the code is on the block facing the firewall. I'll double check when I take it out.
