    I cant find the rod length of a B16B CTR motor. Has anyone acually measured one or knows of a reliable resourse of information on it?

    b16 rods are 134.36 mm (5.29 inches)

    that sounds like A. if the B16B is a B18 block with B16 crank then it should be ~143mm.

    Does any one have a 100% sure of the right number for the b16b CTR rod length??????

    they're equal to eachother ;) just gave him two different units of measurement to choose from. so the answer is 'c' , all of the above. and as far as i know, b16b has regular b16 rods.

    ok, i was definitely wrong about the b16b having b16 rods. i just read somewhere that a guy who tore down his b16b, actually found p72 rods inside, if that is the case, they're 137.9mm

    can't be.

    let's use some deductive reasoning here...

    deck height is the same as a gsr
    stoke is obviosuly different... less displacement.

    so, if you ask me, it would seem that a gsr rod would not work.

    I thought they were the same length as B16A Rods

    Hey B, the stroke is shorter than a 1.8, right, so in order for the piston not to be way in the hole @ TDC it needs longer rods, right?

    katman knows his shit... and i think he meant to type b16b RODS infact.... not pistons.

    .i quote from the site
    « Re: B16b rods different length than B18C5? (allMotor93Hatch) « » 3:33 AM 10/23/2004 Reply Edit

    so you are saying that if i had a b16b blcok and put itr rods, gsr crankshaft, and itr pistons, i would have an itr motor?

    sounds like a lame ass question, but if its true, why not just do that to all of the b16b motors to make them 1.8 liters?

    -------------------------------------------------------------------------------------


    what do you guys think about this?


    and this
    Stroking B16B's is a rather popular thing to do in japan.

    The stroke is 77.4mm... I think.

    to use more deductive reasoning. the pistons are further in the hole then itr/gsr engines. we know this because the compression ratio on the b16b is only like 10.8-11.0 right? and with ctr pistons in a itr engine you get 12+ compression. this further complicates the matter. i guess the only way to find the correct length would be to get one and measure it. maybe 97HB or 97CTR whatever his name is will see this thread. he had a b16b in his ek civic and i remmeber he took out the ctr crank and rods for gsr counterparts. he could measure them

    the compression is lower on the b16b because less stroke/displacement. if you were to stroke the gsr/itr and still use the ctr pistons and piston height it should be around the same to that of a gsr/itr with ctr piston.
