JDM engine features
a) higher compression ratio
b) slightly more aggressive cams
c) different fuel mapping
d) different valvetrain
e) tranny ratios are different

Bottom line stock usdm H22a will never outrun stock JDM H22a (if both in similar condition)
Let me know as i have a lot of JDM H22a engines and complete swaps.
Some have only 15-20k.
