Does it matter which one I get? Thanks in advanced.

 

i might be wrong but the B18B is found in 92 and up ls tegs? and has a lil more hp and torque, i might be wrong

 

The b18a is found in the 90-93 da and the b18b is found in the dc. B18a 130hp- B18b 140 hp. B18b does have more tq but I can't remember how much more.

 

Basically the same engine.
130hp in 90-91, then the later b18B got a better manifold and cams making 140-142 in later years. All B18B engines use OBD1 electronics.

 

Also, for the money, i think a B20 is a better deal. It's the same also, just a bigger bore size of 84mm as oposed to 81mm like the b18.

 

some dood said he has obd-0 b18b? is that possible immean isnt it obd-1

 

he probably just used an obd-0 intake manifold from a b18a

Wrong, B18a was in the da from 90-91 the b18b was in the da 92-93 and in the dc 94-up.

You are wrong.

b18a1 90-91 integra obd-0
b18a1 92-93 integra obd-1
b18b1 94+ integra

 

96+ B18B = OBD-II

ya im pretty sure you are wrong

 

so what is the b18a a better thing to get?

 

There's no "better" Per se, but if you want a simpler swap, 90-91 B18A is fine. Less power, but less wiring. OR, ideally, get a 94-95 B18B. OBD-I and ~140 hp.

EDIT: Really though, the newer the better. You can run OBD-II electronics such as the distributor and injectors off of an OBD-I LS ECU. That's the best of both worlds!

 

yes you wouldn't have to convert to obd1

 

Here is exactly what non vtec b18's come as:

90-91 B18A 130hp, obd0
92-93 B18A 140hp, obd1 -better int manifold and cams
94+ B18B 142hp- (obd1 in 94-95, and obdII in 96+), slight tweek in ecu

here are pics of b18b obd-0 crx





enjoy

 

Nice pics. The B18B is 94+ and YS1 tranny was only in production in 1992 and 1993. That set up makes 142hp.

Its super easy to swap over the injectors, distributor and ecu for 1990-91 model B18A engines.
Looks good, must be fun to drive.

 

i personalyl liked my 94 b18b over the b18a the tq difference was nice

 

in my opinion the B18B is a smoother engine, at least compared to the 1990 Integra I had that was stock. I was never very smooth. I never could figure out why engine was in great shape equal compression across the board. I liked every other 94+ integra I've driven alot better. Maybe I just had a bad one or maybe the 1990-1991 engines weren't as good. dunno

 

2001 b18b1 on the pr4 obd-0 baby needs boost

 

B18B BABY!
