Need a hand with OBD0-OBD1 conversion (B18A1 swapped 1990 CRX)
So I’ve been browsing the forums and YouTube, looking for info on OBD0-OBD1, attempting to turbo my CRX.
my tuner is saying I shouldn’t need injector plugs on my OBD0 harness, although I did pick up some RC750 injectors,
picked up the main harness adapter, and will be ordering a dizzy adapter tonight. But what dizzy do I use, from what I can tell the B18A1 was also used in the 1992-1993 Integra, so will a GS/LS B18 dizzy work?
This is my first turbo job so its very intimidating, but it’s coming along.
Thanks y’all!

Any B Series OBD1 distributer will work in theory. In practice, aftermarket distributers are mostly junk. Try to find an OEM one if possible and if not, expect to replace the ignitor and rotor at the least; the rotor on many is pressed on and the ignitor cannot be replaced without damaging the rotor.
The fuel injector plugs must match the injectors and modern injectors will not work with the OEM plugs.

I got an aftermarket dizzy with a 3 year warranty, I’m going to play dumb if they have any crazy questions lol, what’s shitty is I was finally understanding wiring OBD0-OBD1 just to find out the engine I picked up is OBD1, the one in the Rex rn is OBD0, ordered a **** tone of parts for OBD0-OBD1. I mean they may come in handy but I’m irritated at my own stupidity.
thought 91 was the last year of B18A1, but nope, they used them when they first released OBD1
