Starting a B16 swap in my CRX and I can get a good deal on a B16A2 head which is OBD2 what will I need to for the head so I can use it to run with my system which is OBD1? Thinking obviously an OBD1 B series dizzy what else??? Thanks

 

I believe the dizzy is compatible with OBD1 as most OBD2 sensors are.

 

So what are you saying? I don't need to purchase
anything-I can run it with all the stock obd2 stuff on the head through
my obd1 harness? I'm not that lucky.....really?

 

the heads are EXACTLY the same, no difference at all!

Your obd designation come from your distributor

 

So then all I'll need is an obd1 dizzy for the a2 and i'm good right?

 

Yeah, find yourself a obdI vtec b series dizzy and your good .....or, you could repin the obdII dizzy for the plug, because the inside of it is also exactly the same, as well as the mounting points

 

Repin a newer dizzy or shell out money on an old one... hmmmmmm?!?!

 

usually dizzy, ecu and injectors from the obd system ur going to use. I ran into that problem before converting obd0 to obd 1

 

Well, just so you know -
You can use any injectors. They are not OBD specific. You just have to make sure they have the same flow rate for what your ECU is programmed for AND you have to use a resistor box for low impedance injectors and no box for high impedance injectors.

Also, the only reason you can't mix your distributor with OBD0 and any other OBD is because the reluctor ring inside has a different tooth count and will sent the wrong number of pulses to the ECU.
OBD1 and OBD2 have the same tooth count, but the connector is wired differently.

 

OH MAN!!!!

finding an obd1 b16a2 dizzy is HARD!!!!! look at my thread i've been on standby because i cant find a deal on one..

plus you also need injectors, and in my case i switching out the fuel rail to acommidate my injectors..

 

Finding any distributor is NOT hard, they can be had used by looking around on forums, or, just get one off of ebay. That Being said, you can use any obdI or II dizzy as already mentioned, they have the same wires coming out of them, it's just that one has one plug, the other has two plugs...sames wires, same colors!

As far as injectors go.....NO!! You do not have to change injectors, this is optional and a big miss conception so many people make!

your choices are:

- use any b series obd0 injector ie...90-91 it will plug right into you existing harness, you do NO wiring (d series is 225cc and B series is 240cc if i remember right?)

- use any OBDI or OBDII injector (they have different style plugs from each other, and require you to swap the plugs onto your existing harness), plus you have to modify the wiring to get rid of the injector harness as the impedance is different

 

aw come on LunaLink i showed you where to go to get one.

if you want an obd1 b16 distributor head over to kragen or o'reilly auto parts stores and ask for the following part numbers...
1. Rebuilt w/lifetime warranty # 31-17407
2. Brand new w/lifetime warranty # TD44U


so no more "where can i get the hard to find distributor." same numbers might work for autozone.

 

^ ll..but it was hard finding one until you gave me the part number

lol..you have to use the injectors that fit your harness..make sure they give you the right dizzy, they tried giving me a z6 dizzy ( which i already have )

 

I would also get a obd 1 IM with the IAT bolted to the IM so you dont have to run it on ur intake.. And plug the top vacuum port.. Theres a ghetto way to about the dizzy if you can get a hold of even a Ls obd1 dizzy you just have to cut one of the ears off.

 

^ not a good idea, it still wouldnt be timed right..
well as far as they have told me.
