Could someone tell me what is the difference between B16A2 USDM vs JDM. I know 160hp USDM and 170hp for a JDM, but what is different internal wise between the two. Thanks, just didnt find it in search.

 

Anyone?

 

I believe the JDM one has a bit higher compression, I'm not sure what else. Maybe cams, or header?

 

different cams. that's all. being that the usdm b16a2 have to undergo smog inspections and abide by smog laws, honda didn't carry the cams to the usdm b16a2

and like always..honda always make the cars they import here underpowered compared to their jdm counter parts

stupid US laws >=O
