wow, you must be new.

i dunno how much hp the 04 civic has but i'd venture to guess its less than 150hp.

the b16a has 160hp, b16b has 185. there is no b16c. however, there is a b18c, and there are two variations. b18c1 has 170hp and the b18c5 has 195.

basically, your 04 sedan is a turd. just like all the other civics in the US with single-cam motors. sorry.
