For the 7th gen civic, the HX and EX motors are the same. The difference is the gear ratio. Although I don't know the specifics, I have talked to other 7th gen owners with EX's and this is what I've found. In 5th gear, going 80mph in an EX, rpm's are @4000.
For the HX, in 5th gear @80mph, my rpm's are @3000. Lower rpm's=better gas mileage that the HX is famous for. So I think that the difference lies in the gear ratio/transmission. Also, the downpipe, headers, and exhaust are different.

Honda rates the cars HP not at the wheels, so how would this effect HP
