b18 a or b18b

don't the 90-93 tegs come with b18a/a1 not b18 b

yes.

90-91 tegs have the B18A1 OBD0, which has smaller ports and smaller cams, which make it 130hp.

92-93 tegs have the B18A1 OBD1, with the newer style head which has larger ports, better cams, and makes 140hp.

94+ tegs have the B18B1 OBD1/OBD2 (depending on year), same style head as 92-93, but a better intake manifold and slightly ECU tuning for 142hp

Also of note are the 92-93 OBD1 GSR with the rare B17A1, the first DOHC VTEC engine available in the united states, making 160hp, but slightly more torque than a b16a, accomplished with a longer stroke, but not as long as the B18. It was made for those 2 years only.

thanks civic dude

not to be an a$$ but the first dohc vtec on us soil was the 91 acura nsx, but the gsr was the first affordable dohc vtec.

you got me there, but i was thinking about b & d series, since most people mistakenly quote the 94 del sol VTEC as the first DOHC VTEC
