my name is Dale
i want to start an engine build up on a ls motor for my 91 crx si. my problem is i could get a b18b for 650 w/tranny with less than 50k on it. or schould i just buy a obd0 b18a1 mortor for 450? im not going to use the ls tranny so i could sell that off the b18b. there is a 12 hp difference between the two so i dont know if it is worth the obd change. which one schould i get
 
Code | Disp. | HP@RPM | TQ@RPM | CR | Bore | Stroke | Cams | VTEC | OBD | Production
B18A1 | 1834 | 130@6000 | 121@5000 | 9.2:1 | 81 | 89 | dohc | no | 0 | 1990-1991 Integra GS/RS/LS/LS-S
B18A1 | 1834 | 140@6300 | 121@5200 | 9.2:1 | 81 | 89 | dohc | no | 1 | 1992-1993 Integra GS/RS/LS/LS-S
B18B1 | 1834 | 142@6300 | 127@5200 | 9.2:1 | 81 | 89 | dohc | no | 1 | 1994-1995 Integra GS/LS/LS-S/RS/SE
B18B1 | 1834 | 142@6300 | 127@5200 | 9.2:1 | 81 | 89 | dohc | no | 2 | 1996-2000 Integra GS/LS/LS-S/RS/SE

All parts in the B18B1 are essentially the same as in the B18A1. Now, to get more technical. The B18B1 has more HP, and 6 LBS FT of TQ. I;ve heard that the B18B1 is a little more stout, but like I said they are essentially the same engine. LSVTEC (Eric) told me the only difference between the 90-91 B18A1 and 92-93 B18A1 was OBD systems, Intake and Exhuast Cams, along with the Exhaust manifold. Thus giving the OBD1 Equipped B18A1 from a 92-93 Integra 10 more HP and 6 more LBS/FT of TQ.

Im sorry for all the abreviations such as:
TQ=Torque
HP= Horsepower
LBS/FT=Pounds per Feet
Disp.=Displacement

Since a B18B would be a little more expensive than an A1, I say go with the A1 from an Integra.
 
id say keep it simple and stay obd 0, it sounds like cost is a factor for you and this would be the less expensive way
 
cost is kninda a factor but i want to do it right the first time.
 
get obd0 period.
obd1 is not more porper than obd0 since thats what your car comes with.
if you planned on mega power or something or wanted to use the Hondata management system then yes OBD1 would be nicer but there is also Zydyne for OBD0 engines so if cost is a factor i would suggest OBD0
