Default b18c1 swap into 91 si hatch.. which dizzy is needed?

I believe its the b16a obd0 jdm dizzy but I am not for sure.
Will any other obd0 dizzy work? Maybe from 92 gsr OR 90-93 LS?

B16A obd0 dizzy is perfect...90-93 LS will work too but you have to cut one of the mounting "ears" to fit (can only use 2 bolts as suppose to 3).

B16 OBD-0. Do not use an LS, it was not ment to rev that high and may misfire at high rpms.

If you need to replace the cap, rotor, and coil etc.. what do you tell the person at the parts store as far as which car it is for if I have obd0 b16a dizzy?

i'm pretty sure 90-91 teg cap and rotor would fit.

I had a non-obd b16 on my gsr motor and when that took a dump I used a brand new non-obd LS dist. with no problems whatsoever.

If i were to just replace some of the parts such as cap, coil, stuff like that WHICH car do I tell the person at the auto store the motor came from since there was never an obd0 b16a in america? Is it the same as obd1 or obd2 b16a distributor as far as whats inside? WHat makes the obd1 or 2 not fit on a 1991 civic si?

That couldnt be farther from correct. All the obd-0 multipoint distributors have the same internals. That includes the stock crx/civic si and hfs.

So I could use one from a DA? What modifications do I need to make to do this on a b18c1 in 1991 civic si?

And I guess you kind of answered my other question as to which parts I can swap out into my existing distributor... In other words I could just ask for cap and rotor coil and etc from parts store for ANY obd0 usdm motor correct?

I have a mint conditioned b16a obd0 distributor for sale, near new cap and rotor. $150.00 plus 10 for shipping. Ryan

Like was posted above, the LS distributor will work, but you will have to modify/rig it to fit. The only bolt on is the obd-0 b16a distributor. I picked one up a few months ago for $25 and swapped in some DA internals i had laying around. The only problem is that obd0 distributors are sometimes a bitch to work on. They are put together with hollow tip torx bits that love to snap off.

B18C1 + 1G JDM B16A ECU = Halfass.

Its because its obd0, and it could run obd1. Either is fine in my opinion. Ryan

But I thought if you have OBD0 wiring such as my 91 civic si, You have to use an obd0 distributor? Isn't this why the only one that bolts on for my year car with b18c1 is the 1st gen b16a dizzy?

You can always convert to obd1 and use the b18c distributor. This way everything is the way it should be

Check the link in my sig for conversion harness info

Think of the dizzy as your head, you have 2 ears that stick out, that's where the dizzy is bolted down. On the otherhand, a dizzy have 3 ears, 1 bolt on each ear. If you try to use an LS dizzy, you will find out that one of the ears will hit the vtec solenoid so you must cut it off and bolt it down using only 2 bolts.

* B16A non obd distributor have the same internals and cap and rotor as all non obd LS distributors.

* Only downside in using a modified LS distributor is you can only move it so much therefore limiting your timing adjustment capabilities...

* I also have a B16a (non obd) dizzy for sale, $150 shipped, in case you're interested. I'm sure you can get em cheaper anywhere else too...cheapest I found is about $130 shipped here on HT Classifieds

Good luck

obd0 dizzy will work.
B16A obd0 preffered and best option
B18A obd0 not recommended

odb0 on B18C1(stock form) does not make the full range of power from the motor. Would recommend getting obd1 ECU and electronics due to the butterflies and other issues.

Are you sure about this comment? I have a zydne chipped pm6 ecu which uses b18c1 mappings and dual butterflies.

That couldnt be farther from correct. All the obd-0 multipoint distributors have the same internals. That includes the stock crx/civic si and hfs.

You don't have to believe me if you don't want to, but I learned the hard way.


The dumb a$$ mechanic who installed my engine used my old distributor and converted the engine to OBD-0. After running a 15.9 I went to the shop pissed off and demanded they fix it after two dyno runs of 120whp we noticed the dyno chart was skipping around and asked what that ment. They said it was a high rpm misfire after changing to an OBD-0 B16 distributor that fixed that problem.
