    Why would you want to do that?

    To spare you from the "why would you want to do that" lecture that people here love do bestow upon anyone asking a question, the answer is yes, they fit.

    hell my ls even has p73 jdm pistons in it, i had to do a little ::cough, bench grinder cough:: machinework to the rods to fit but that is only with LS engines, any other b series i heard they fit direct.

    have fun and good luck

    Putting ITR pistons in a b16 will lower the compression.. Use Civic Type R pistons. It will only bring you up to about a 10.8:1 range though...But with a 2ply head gasket you should have a 11:1... best bet is forged..

    Only if they're USDM ITR. JDM ITR's will raise the compression.

    Duh.

    both USDM and JDM ITR pistons will lower the compression of a B16.

    the USDM ITR piston will lower your compression to 9.72:1
    the JDM ITR piston will lower your compression to 10.19:1

    a stock B16A with PR3 pistons has a compression of 10.20:1

    i calculated all of those with an OEM 3-layer gasket.

    if you're trying to raise the compression than the only 2 OEM pistons you should consider are the P30 and the PCT.

    P30 = 10.40:1
    PCT = 10.80:1
