    No, it won't be worth it. Better pistons, but not worth it.

    Only thing thats worth it is aftermarket pistons, or CTR pistons.

    says their dome.

    they have a smaller CC than b16 pistons.

    usdm itr: 3.64
    usdm b16: 6.01

    jdm itr: 5.96
    jdm b16 : 6.93

    jdm CTR: 8.63

    usdm gsr: -0.60
    jdm gsr: 2.52

    usdm b17a gsr : 0.0

    right, but an overall higher c/r right? so in theory it would produce more power. Not alot, but some.

    in a gsr motor -

    usdm itr -10.8
    jdm itr -11.3
    b16 - i can't remember, 10.0 i think

    no.

    putting itr pistons in a b16 will LOWER the compression.

    the pistons have a smaller dome, and thus, make less compression

    Well, what the fuck. Those are alot cheaper than the itrs I had in my car. and mine were only 10.8:1. Wish I had known that.... Are you noobs paying atention? :p j/k

    Dude, that calculator is sick. good hookup. so ctr pistons in a b20/vtec with a b16 head, stock deck height, stock head gasket is 13.0:1 c/r ...... wow.... B)

    they will work on the b16 or ls rods you just have to have them machined down a bit so they fit because the rods are a little thicker on the b16 and ls. a machine shop can get them to work
