    Does anyone know where the extra 3 hp come from in the jdm b18b1 as opposed the usdm model? I was told its due to slightly more agressive cams, is that true? Post back.

    I would say that a 3 hp difference is just due to the testing facility and the engine, you can take brand new cars exactly alike and get varying hp readings, every engine does not have the exact same amount of hp, it would be impossible.

    That is why the motor companies use SAE Corrected HP when rating engines. It takes into account the atmospheric conditions at the testing facilities. They also average the output numbers for their test engines, as there is always more than one.

    To answer the question, the b18b has slightly more agressive cams, as well as a slightly better exhaust manifold. There could be other slight changes to the engine that account for the increase in power. I thought the b18a1 was rated at 130bhp, while the b18b1 was rated at 140bhp?

    You are correct, the b18a1 was 130hp between 1990 and 1991, but in 92 the engine went to 140, there was a difference in the cams as well as the changeover from obd0 to obd1

    original question though was the b18b1(usdm) v.s the b18b(jdm) engine
    The SAE net hp is set for the usdm models, but JDM engines are NOT SAE TESTED because they are not sold in usdm cars, so horsepower figures can vary slightly due to whoever does the test.


    I fully believe that the jdm engine may have a few extra hp, and it could be anything from how the engine was tested to what condition it was in when tested, and the emissions on that engine.
    Either way, after all of this, who would pay the 600 bucks+installation for a b18b jdm engine just for 3 hp?​

    Nobody, thats retarded. But if you so happen to have a stripped block and you need a new motor theres nothing wrong with 3 extra horses.
