any difference in cam specs (jdm vs usdm)? or difference in anything for that matter with an H22A

 

nope. but there is a diff in the type s and r's. but you know that already. the 99+ type s is VERY bad for 92-96 h22's because the seating of the valves is different. they will slowly wear on the earlier valves. if you want power...go for the euro inspier type r's. they're hard to find but well worth it. just check out the spec's. also the euro/jdm acc f20vtec. very nice durations and lifts.
