jdm engine difference?

There are a few differences. The biggest is the harness, which is for a RHD car, and may just be cut anyway. You'll have to swap it with yours. The throttle body is different. There is a coolant tube that runs along the exhaust side, and around the back, thats different. EGR is blocked off on the JDM motor, might just want to leave it that way, unless you think you'll have an emissions problem where yo ulive. Some of the vacuum routing is different I believe, and there are emissions sensors under the intake mani...I don't think the JDM motor has them.
Thats all I can think of.
Make sure the JDM motor you get is like this....I've seen some of those guys try to pass off salvage US motors as JDM.
