I'm compiling parts for a swap I'll be doing soon. I have a 90-91 integra dizzy. I am hoping to be able to bolt it up to my new engine which is a b18b block with a b20b head. Is the bolt pattern the same with that dizzy on the b20 head? I also had another question.... are all the b series dizzys bolt patterns the same? I mean, are all the b18a and b18b dizzys have the same bolt pattern just different plugs?

I was wondering becuz I can also just get a b20 dizzy and swap the plugs on it with my obd0 plugs.

 

non vtec dizzys should all have same bolt pattern as they are all PR4 heads

just be careful if you choose to use a b20 OBD2 dizzy when you rewire the plugs

 

thanks for the help....but wut do u mean by "be careful"?

 

I think the 90-91 will fit.

My experience is that the 92-93 have a different pattern. I have a 90-91,92-93 and a 94-95. When I went OBD-1 I bought a 92-93 and it would not fit my head which was a 95. When I looked at all three side by side you can see the difference.

The B0 will not work unless you have changed to OBD-1.

Yes, I have a 91 B18a distributor on my 95 B18b engine and it bolts up fine and allows the timing to be adjusted to specs. BTW, both plugs fit the 90 HF wiring harness.
