P30 pistons, brand *new* in the box
got a set of 4 P30 (ek civic type R, B-series engine) pistons at my brother's house in Connecticut that I need to sell.
Great upgrade for GSR block with Type R heads. Will fit any B-series motor.
Will take $200 for the set picked up. (price is always subject to negotiation)

Re: P30 pistons, brand *new* in the box (pstereo)
Actually, the P30 pistons arent from a Civic Type R (B16B). The P30 pistons are from a JDM B16A. B16B pistons (CTR pistons) are labeled PCT. Those pistons are slightly higher in compression than USDM ITR pistons. In a stock GSR, ITR pistons will give a CR of 11.04:1, whereas the P30 pistons will give 11.5:1. 
Good luck.
Good luck.

Incorrect.
PR3 = B16A
P30 = B16A2
PCT = B16B
Your compression ratios are also slightly incorrect:
PR3 will put your compression around 11.1:1
P30 will have your CR near 11.33:1
PCT Puts the CR around 12.6:1
Good luck.

Incorrect. All USDM B16's came with PR3 pistons. JDM B16A's came with P30's. And my compression ratios are spot on. Check http://www.zealautowerks.com if you dont believe me. And every compression ratio calculator is different, numbers will vary slightly.
According to that site- with an otherwise stock GSR:
P30 = 11.5:1
PR3 = 11.28:1
PCT= 13.09:1

Re: P30 pistons, brand *new* in the box (Sirfallsalot243)
sigh...
Im not going to get into this argument, again. And let me correct myself: I thought you were implying that PCT = p30... -> Misread.
Bump for a great deal.

No, the OP was implying that P30 = PCT. I corrected him.

But yes, they are the Civic Type R P30's (JDM)</TD></TR></TABLE>
Lol, we just went through that. No they arent. Civic TypeR pistons are PCT.
P30 is from a JDM B16A, which didnt come in a CTR.

No isht?? I thought it did. hmm learn something new everyday.
Wait, didn't one of the JDM version of the DelSol have these?
