What makes the JDM B20A more powerfull that the USA VErsion

[SharkyX]

i was juts wondering what the major diffs were that gave that engine such an advantage, and also are there any of the parts off that engine that can help the performance of our engine. IF this has been asked please let me know. I just couldnt seem to refine my search enough to find this.

If you're talking solely on engine for our cars, B20A and A20A are completely different. B20A has DOHC while our is single. It probably has a higher compression ratio and different fuel maps and ignition timing to make more power. As far as part swapping, good luck.
