    pr3 and p30 are NOT the same. p30 will raise your compression over the pr3

    one place that i always refer to when i'm trying to find parts is JHPUSA. here's the link for the P30 pistons. they're reasonably priced.

    JHPUSA.com - P30 link

    The site is a total rip OFF. A set of p30 can be had for under 125. Check sale forums and ebay

    you need to keep in mind that those are a brand NEW set of pistons.
    plus, it's still a lot cheaper than some other places. such as:

    InlineFour - P30 pistons - $200

    and it's still cheaper than ordering it through Honda.

    PR3 = USDM B16A
    P30 = JDM B16A

    Per the Honda EPS:

    1995 Honda del Sol VTEC

    Piston set (OS 0.25) 13020-P30-G00 List price $57.10

    WTF is a PR30 anyways?

    Yeah, that's a good deal. You can usually reuse the wrist pins- just replace your rings.

    105 shipping is right on. Those are perfect for what you are looking for. Remember to replace the rings, its not worth the gamble.
