Re: B18A----B18B
Biggest difference is OBD0 90-91 ignition timing versus OBD1 92-00 ignition timing. That, and the extra 400 rpms revlimit, is where the extra "hp" comes from. You can compare "bigger" -B intake manis and intake cams and nonsense all day long, but 90-91 = 130, 92-93 = 140, 94+ = 142.
It's in the ECU...

Re: B18A----B18B
But the b18a1 90-91 also shares the same mani/tb has the 92-93 b18a1 so that kinda disproves me own thought. Only difference I have found in the 2 is the casting in the 92 seems cleaner than the old pr4 manifolds and the short base iacv on the 92-93 manifolds but once again this is just rambiling

Re: B18A----B18B
90-91 are "small port" heads, but that means absolutely nothing. Look at LS vs VTEC performance in equivalent NA cars up until 180+ whp... LS owns. Listen to mototune guy, smaller ports can be a good thing. *cough* SR20DET *cough*

ok now does the 92-93 b18a integs use the obd1 ecus
?? if they do are all the sensors the same as the 90-91 tegs with the b18a?? im sure the plugs are different but the obd1 is much more tunable isnt it. does any one know anything about the edlebrock victor x turbo setup-------ist it worth it------just wondering cuz i get a hell of a deal on them.

88-91 Civic/Integra OBD0, 92-95 Civic/Integra OBD1
There is a difference between OBD0 and OBD1 distributors, 16 vs 24 tooth CKP sensor, that makes them incompatible.
Asking about kits on HOMEMADETURBO is a good way to get fucked in the ***, n00b. We are men, not consumers.
PS - I don't think anyone mentioned 90-91 small spline/92+ big spline transmission input shaft differences. You need the correct year PP, disc, and flywheel depending on which trans you run.
