91-92 integra b18 question

ok i've got a question..... the 90-91 integra came with a b18a engine with 130hp and the 92-93 integra (not including the GSR) also had the b18a with 140hp..... So what is the difference in the engines between 91 and 92???? I have a 91 LS,.. what can i do to gain that 10hp the 92 has?

i hear its cams, not really 100 percent sure.

cams huh, well that sorta makes sense i guess.......the 92-93's could have a more agressive cam i suppose.....too bad, i was hoping it would be something different, if i replace the cams i might as well go with aftermarket cams from Crane Cams or something..... if anyone is 100% please let me know

its not the cams......i put 97 LS cams in mine and it did nothing......the difference is in the head design and the fuel mapping.....to get the 142 hp that the new LS engine has....swap the new LS head and valvetrain and get yourself a skunk2 IM, then an A'Pexi S-AFC......you should be good.....another thing to think about....the 94-up (not sure about 92-93) internals were forged as opposed to the cast internals of the 90-91
