Go with JDM, they usually have higher compression due to japans higher octane gas. Just expect to see a little bit of smoke come out of the tailpipe every now and then, oh yea and expect to be paying for 93 octane.

Fuels in the U.S. are described in terms of their "Pump Octane", which is the average of "RON" (Research Octane Number) and "Motor Octane Number". Labels on gasoline pumps in the U.S. typically describe this as the "(R+M)/2 Method".
Some nations describe fuels according to the traditional "RON" or "MON" ratings, so Octane ratings cannot always be compared with the equivalent U.S. rating by the "(R+M)/2 method".
