Ok well I bought a 88 crx si and it came with a b18c swap. So my engine went out and I want to put in a b18b. So what parts would I need need to get to convert the engine from obd1 to obd0? So I searched and I know I need a 90-91 ls computer and distributer. What else would I need and what parts can I use from my old b18c swap?

Would I be able to use my b18c injectors on my b18b?

 

You can use the GSR injectors. All stock injectors are the same except for H22 and b18c5 (Type R) I believe. Correct me if I am wrong. If you plan on going obd1 you will need either a 91.5 - 93 pr4 ECU or a p75 ECU out of a 94-95 integra.

Depending on what plans you have for the car, I would just fork out the cash and buy a chipped ECU with what your engine is, that way you can just change the chip out i.e if you plan on running any Forced Induction.
