    No EGR I think is the major difference.

    no egr, different exhaust mani iirc, and different ecu (fuel maps and timing i think)

    According to Wikipedia:

    JDM could run a little more agressive because they didn't have all the polution control stuff that the North American version needed to pass inspection in all the States. More importantly the fuel over there is higher octane allowing for higher compression and more advanced timming.

    only difference in the exhaust mani is the hole for the EGR pipe

    I do believe its sitting ontop of the motor next to the intake.

    BTW I had to pirate a hose clamp off your motor.

    What kind of dif does it make?
  16. CrazyAchmed

    CrazyAchmed Well-Known Member Donated!

    Probably better fuel/timing curves.
  17. slow_yota

    So better throttle response/mpg?

    IMO, you REALLY need to get one if possible.

    I've got a JDM gen 1 ECU, my car ran like shit with it and made 116hp vs 123hp on the ADM spec ECU. We're going to try playing with timing and run better fuel for the next run as we only did a straight back-to-back comparison, but don't believe the hype.
