hey i have a 91 civic si and i got a full 93 b18a1 swap to put in. i have the motor, tranny, harness, axles, and innovative ef b series mounts. I was wondering what else i need. ive heard that i will need a distributor from a 90-91 ls. is this true. also someone told me i have to wire the injectors without a resistor box. if anyone could explain to me how to do this that would be great. thanks.
 
you will need the older dizzy if you intend on running the car with an obd0 ecu. if you were to run it with an obd1 pr4 or p75 though then the 92-93 dizzy is what you want.

as far as the resistor box goes, you need to delete it in order to run the saturated injectors. start by physically removing the box from the car, obviously lol. then take the 5 wires that went to the resistor box and solder them together. simple as that.

other stuff you will need:

-ecu (obd0 or obd1, that's up to you)
-da throttle cable
-b-series into ef shift linkages, or shortened teg linkages
