Jdm or Usdm?

[Fatal070]

which is better and which will be easier to put in and get parts for.

Eh, better would be personal taste with accessories, but JDM engines are usually better.

Easier - USDM because its right here.

Keep in mind.. JDM probably wont pass emission if you have to worry about them, unless you put emissions stuff on your self.:o

[blind34_1]

if its a toss up for you then go for the cheap usdm stuff. If you like the subtle, function over form doctrine then go jdm.

If you are content with jsut a swap go JDM. If you want to take it further later down the road go with a usdm motor and then work the internals. If you do decide to get a JDM motor and need to pass emmisions that is no problem there is more than a few ways to pass with a few tweaks. Most of the time you can back down on the fual pressure or even add something that burns cleaner like a gallon or two of alcohol. I even had a buddy of mine pour a gallon of MTBE from home depot in his car to pass emmisions.

Xcuse me for being ignorant, but what really is the difference in JDM and USDM

depends on the motor, its usualy compression or something like that. less emmission devices, higher red line.... it varies

JDM in my opinion

[blind34_1]

JDM-> Japanese Domestic Market
USDM -> US Domestic Market
EDM - European Domestic Market

JDM cars usually are just made better; engine, looks, everything. They generally have more powerful motors, better interiors (like power locks and windows standard), and right hand drive. They are also the only true Type R's (except for the type r integra, that you can find here). This is also why people go ga-ga over jdm nissan skylines, cause they are a superior car in every way.

J-spec is another term that people seem to use interchangeably with JDM, but I think they are wrong. J-spec refers to aftermarket parts that are of a high enough quality that the japanese, who are concerned about the best performace, will use on their cars.
This kinda means that a Tanabe exhaust would be considered jspec, while a pacesetter exhaust would not be.

EDM isnt really a concern for most people, because while some of the edm cars have better engines, they're just not as desirable. I actually dont know too much about their stuff.


Please someone correct me where I've gone wrong here, I'm sure I made a mistake somewhere.

this is just my take on jdm vs. usdm


also, maybe a JDM forum section might not be a bad idea (?)
