jdm usdm?

WHATS THE DIFFERENCE? JDM IS JAPANESE MARKET AND USDM IS US MARKET. WHY SUCH A DIFFERENCE IN PRICES AND PERFORMANCE. IM LOOKING TO MAKE MY LUDE KICKASS AND WOULD LIKE TO GET SOME IDEAS FROM YOU GEARHEADS OUT THERE WHO KNOW WHAT THE %*@! THEIR TALKIN ABOUT. ANY DIP&%#$ CAN PUT I/H/M ON THEIR CAR AND CALL IT FAST BUT I WANT MY CAR TO BE MORE THAN THAT. HELP OUT THIS MIDWEST LUDE LOVER.

usdm is more restictive than other markets when it comes to emissions....that's about it:bigthumb:

JDM products are of better quality, the engines produce more horsepower than their USDM counterparts, and it's cooler to say your shit was from Japan I guess. Don't ever drive to California, Pennsylvania, or anywhere else where they're strict on emissions laws though.
