quick rundown of the specs there

 

man okay one is made in "JAPAN" and the other is made in the "U.S.". there you go now you know the difference

jdm by a hair by the way

 

both are similar with minor changes like compression etc

x2 ...

 

Some are more different than others, depending on which motor you're talking about. For example, the B18C (jdm) is 180hp whereas the B18C1 (usdm) is 170hp. Not true in all cases though.

 

JDM is more mony but a lot better looking and quality

 

there is no answer to which is better. lets talk about Dseries. i got a D16z6 1.6L sohc vtec makes 127 flywheel horsepower, i also got a JDM D15b 1.5L sohc vtec and it makes 130hp. basically the same out of a smaller motor, why???? no emmisions in JAPAN, therefore they can run higher compression from the factory, and have higher octane fuel. on the other hand you have cost. USDM is definately better in this case, so which is better a few HP or a few $k, you decide.

Also, for us CA residents, JDM is a PIA because of smog referee issues...

 

Aren't JDM use are ment to use higher octane..

 

well since many of them have higher compression than their USDM brothers, yes they should use higher octane
