As I understand these came in the JDM 2nd gen B16A, right? A guy on G2IC recently discovered that the 1999-00 Civic Si used a piston with a P30 part number. Is this true, or do they use the PR3?

No one knows. Wow...

they're basically the same motor,so i would guess they do use the same piston.

a friend of mine just bout a 2nd gen B16A Auto (Del Sol VTEC?).. pulled the head and it has P30 pistons. im guessing the jdm version b16's have P30 and US have PR3

They might be "Basically" the same, but the 99 Si is 10.2:1 compression whereas the second gen JDM B16 is 10.4:1. The pistons are slightly higher domed on the JDM engines compared to the US. Far as I know, the piston I pulled out of my SI was casted as "PR3"..in fact, I am holding it right now. Clearly stamped into the top "PR 3". Interestingly enough I have it in the box the replacement piston came in and it has a P30 part number. I do recall however that the piston was casted as PR 3.

Thanks for the posts, guys. That SL Honda is a good site, never seen it before.

Anyway, I also found this part number for the '97 Del Sol, all other years were PR3s:

13010-P2P-000 PISTON SET (STD) $41.27

Wonder what that one is? Probably a PR3, too...

I don't understand why Honda would list the replacement pistons for the Si as a P30 part number. That sucks ***, but I guess it can't be that easy tpo get he P30s.

Again, thanks for helping me out and shedding some light on the subject.

P2P is an EX part number. So I am assuming you looked up the Del Sol Si. Couldn't tell you why the part number has a P30 in it, but I can tell you I know for sure they are PR3's. I blew my **** up and had it apart. I remember exactly what it had.
