Sup guys, I have a question that has probably been anwsered before but unfortunately I've had no luck when using the search function...anyways here it goes.
Are the OEM pistons for the 99-00 Civic Si the same as the JDM P30 found in 92+ SiR Civics? The part # Honda has listed for these pistons is :13010-P30-G00
It has the number P30 right in there, but is it safe to say they have a compression ratio of 10.4:1 and not the usual 10.2:1 of other USDM B16 pistons? (Del Sol)
Thanks in advance

crap, can anyone confirm this? I just bought some OEM 99-00 Si pistons for dirt cheap and since the part number has P30 in it, I was hoping they were teh same as the JDM P30's. Oh well

 

They are the same as the JDM P30's, the only piston we got in the USA for a b16 was the PR3.

Now I'm confused...what you said contradicts itself, please explain.

 

The only piston we got in the USA for a b16 was the PR3. 99-00 si = pr3
