I just did an OBD-0 to OBD-1 conversion on my DA with a 1st gen b16 swap. I bought all the wiring adapters, so it would be plug and play. I have a p30 computer. I am running a 94 Del Sol b16a3 distributor that I bought brand new.

I plugged everything in, made the necessary splices, started it up. And it wouldn't run for more than a few seconds. No Check engine lights, just wouldn't run. I found it would only run if I pulled the bolts out that are holding the distributor and retarded the timing as far as it would go (which now makes the bolt holes way off...making it impossible to bolt the distributor back in. I actually have only the top bolt in...holding the distributor fully retarded. And it runs ok, with a little miss.

Whenever I drive it now, it feels sluggish. It runs a great deal better and smoother, but it is very sluggish. I know that the ignition timing is off. Everything else is fine. I didn't change anything else, I drove the car home from work, and did the conversion in under two hours.

My question is about the dizzy. Will a del sol b16a3 dizzy work right with a jdm b16a? Or should I be running something else?? Any other ideas would be greatly appreciated.

Thanks

 

I have pics but I don't how to upload them.

Did you check your spark plugs and wires? I would also check the ignition coil with a voltmeter to make sure it is withing specs to assure you arent getting a weak spark.

The USDM and JDM distributors are the same, i dont believe they would make a difference.

 

Well, the fact that the spark plugs and wires worked perfect an hour before the conversion would eliminate that chance. I haven't checked the voltage off of the coil, but I don't think it is that. You see the distributor is cocked so far back that it is in complete contact with the VTEC solenoid. I have to put the bolt in BEHIND where the bolt hole is to hold it cocked that way.

I have played and played with the firing order, I know it is right. I verified it with a buddy's car.

It is a remanufactured distributor, so I am leaning towards the possibility of a bad distributor.

It is either that, or an obd-1 VTEC distributor doesn't fit on an obd-0 b16 head without serious mods to the dizzy.

 

Could anyone coach me through uploading photos into a post so I can show you what I mean...cause it is difficult to explain.

Thanks

The distributor does not require modifications to fit, any obd distributor would work assuming its the right obd type or wired right.

What systems of the wiring harness did you splice? I would recheck your connections for the ignition as well as the fuel injetors. Are you still using a resistor box for your fuel injectors?

 

In order for me to put that dizzy on, I had to saw off the bottom leg, because it came into contact with the vtec solenoid. I know it's wired right, because I bought an adapter that is supposed to work with the other components included. The only splices I had to make were to the vtec solenoid, pressure switch, knock sensor, and the four 02 sensor connections. everything else plugged in. The splices are good, cause there'd be a check engine light. I am still using stock obd-0 injectors with the resistor box. But other than those seven splices, there basically was no wiring.

Maybe there is some small difference in a Del Sol VTEC distributor. I don't know.

I just got an idea...anyone know what distributor part number I should be using? Cause I just looked on autozone.com's catalog, and there are two different dizzys they sell for that model...one is a td-22, and the other is td-44u. I checked in on an acura b17 gsr engines part numbers and there is only one dizzy that works, and that's td-44u. I bought a td-22u, so I wonder if that would cause the problem...any ideas???

 

You might have an LS distributor, because thats the only one i recall requiring a leg to be cut off in order to work. But something doesnt seem rgiht because you have it retarded/advanced to where it hits the vtec solenoid.

 

yes you will need the b17 dizzy

 

Just put on the b16a3/b17 dizzy today. That was definitely the problem. The car runs perfect now. Way faster than with obd-0. The conversion was definitely worth it!!

Thanks for all your help!

 

i just read this. what year is your teg? 90-91? OBD 0. needs an obd0 distributor and injectors and ecu. 92-93 obd1. needs an obd1 dist., inject, and ecu. just in case you needed anything else. let me know if u have more problems. i have a jdm b16 in my 93 da.

 

hey what u do the injector resistors block like the wirring on it please email back at yang475sac@yahoo.com
