My engine builder just ordered me some NPR P73 pistons and it said JDM integra Type R on the box, but the top of the pistons say p73 AO and I understand the JDMs are OO, right? Just wanna get a second input on this cause I dont want to get screwed and buy somthing I didnt intend to.

 

took me less than 10 sec. to find this on google search

Yeah, i know THAT, but it says AO on the pistons and JDM ITR pistons on the box. AND my engine builder says its all the same by NPR

 

Just because I give you a hamburger with a cheeseburger wrap out front doesn't mean it's a cheeseburger. Now look at the link above, it tells you how to read the pistons. I mean read the pistons not the box.
