I'm sure this has been covered a million times, but I searched and could not find what I needed. So what are the differences between these two motors? Or please list some links to help me. Thanks.

 

engine wise..its the mainly the cams and intake manifold.

remeber that the b18a1's came in 2 different ratings

 

I have a motor from a 92 Integra. Is this OBDI or OBD0? I am going to install a B18B head on the 92 block. Is there anything on the block that needs to be changed to OBDI, if it is OBD0?

 

94 and up B18b1 142 hp 127tq

90-91 B18a1 130 hp 121 tq (obd0)
92-93 B18a1 140 hp 121 tq
The 94-95 B18b1 (obd1) is the best LS motor

me or?

i also agree on the 94-95 statement....but ist not really the engine that is better, it the obd. obd1 is always going to be more forgiving then obd2.

 

So if one were to convert to obd1 would that be the same as a motor that came with obd1?

So a 92 B18a1 is OBD1?

ayy man i dunno but i felt so many obd2 ls compare to obd1 94 ls. the 94 ls seems to pull alot harder then the 98+

 

So I have a 92 B18a1. When I swap the head to a B18B, I can reuse my distributor right from the 92? After the head swap it will basically be identical to a B18B Obd1? Just wanna make sure I can reuse the B18a dizzy.

yes the heads are the same

 

92 would be obd1

 

Well this is very helpful, as im looking at a b18 for my soon to be new car. how hard would it be to drop it into a da?

um probably as hard as replacing the engine with the same thing

 

probably a dumb question but would a 94 LS motor fit directly without any mods into a 92 LS body? i might need to swap mine out due to high milage soon so if it fits directly than i rather get a 94 instead of a 92.

a friend of mine has a 94 b18b in his 91; ill ask him to be sure but i think its the same. its basically the same exact engine.
