    b16 1600cc b18 1800cc

    Most commonly a larger displacement will have larger pistons;)
    compression ratio is not entirely significant in this case.
    Neither is running a (gsr)vtec ECU on a non vtec motor.

    detonation, piston meld down, main rod and bearings being chewed up, fling a rod, crack ringland, crack a sleeve, scratch up skirts and walls......in short dont to it, you will have major engine falilure.

    If you have money to build a engine you should have money to tune it.

    B16a/b and B18a/b both have 81mm bore and same sized pistons. stroke, rods,deck high, and crank is diffrent.

    also compression hight, piston dome, and pin hight all play factors in CR.

    I agree, they are factors. Just not significant. If I understand his thread right, he is wanting to know why he cant run his b16/gsr ecu with a b18 motor.
    Where compression ratio is a factor/significant?
    I suppose unclear questions will get unclear answers. :rolleyes:

    Should you run a stock B series VTEC ECU on a high comp build? No

    Can you? Yes

    looks like he wants to run a 11.6:1 CR on a LS non vtec engine and run a P72 or P30 ecu.
