Im swapping a 95 d16z6 full swap (including converting to obd1 w/ jumper harness and p28) into my 96 dx hatch and im running into a few problems. I know I have to swap the distributor plug but some of the wires between the harness and distributor dont match each other. Im also having a tough time figuring out the plugs and wiring on my new intake manifold. I cant figure out which plugs go where. I have been doing a bunch of searching but havent found anything too good on my swap but I know it has been done. Thanks, sorry it was so long.

should have just got a d16y8, would have made your life alot simpler

 

no need for search, this was found in the FAQ section at the top of the forum....

obd1 motor into obd2 car....

I have tired to search but I can't really find anything. thanks&lt;HR&gt;&lt;/BLOCKQUOTE&gt;

funny, about 3 people emailed me this same exact question at the beginning of this week and here's the info I relayed back to them:

"If you want to use an OBD1 B16A engine in an OBD2 equipped vehicle (such as yours), then you'll have to:

1) Reuse your existing OBD2 engine harness and add the respective VTEC wiring and Knock sensor if you own a non-vtec 96-00 civic...OR... find a 96-98 EX engine harness which already has the vtec wiring & knock sensor embedded into it.

2) Find a set of B-series OBD2 injectors...OR... or cut & splice the OBD1 injector plugs and adapt them to your OBD2 engine harness.

3) Find a 96-00/OBD2 B-series alternator ...OR... sell/trade the OBD1 B-series alternator for a 96-00/OBD2 B-series alternator. The plug is a square type on the 96-00 alternators and has 1-2 more wires leading to it, whereas the OBD1 alternator plug is a bigger round plug and has less wiring going to it. So there might be an issue if you try to rewire it...your best off fnding an OBD2 B-series alternator though.

4) Find a 96-98/OBD2 B-series distributor which will plug n' play w/your DX engine harness....OR...they say you can convert your OBD2 distributor plug to OBD1 spec by repin it to a dual OBD1 plugs and will accept & utilize an OBD1 distributor. I've never done this myself and I find a big pain in the *** (I personally hate rewiring stuff)....I suggest you find a 96-98 B-series distributor to make life easy on yourself.

5) ECU.
If youd like to go OBD1 ecu, purchase a 96-98/OBD2--&gt;OBD1 ecu jumper and simply use an OBD1 ecu. JDM OBD2 ecu's programming is similiar to OBD1 programming as far as looking at sensors. It looks at the same exact sensors an OBD1 ecu does.......but for the US version of OBD2 ecu's programming, they look for a few more sensors which makes OBD2 a hassle.
US OBD2 ecu's look for these additional sensors:
- CKP (an integrated crank sensor thats found & embedded on the oil pump)
- 2nd 02 sensor

The CKP sensor is the big downer, since OBD1 and JDM OBD2 engines do not have this sensor. If you want to add this sensor, you need to change your oil pump to a US spec 96+ B-series oil pump. Again, you can easily avoid all this frustration & wasted $$$ if you go with a JDM 96-98 ecu or the OBD1 route.

katman rocks

 

thanks man, I made the thread but im on a friends comp now. Hopefully this will solve all my problems

 

Ok so I still have a couple questions. My engine harness plugged onto the injectors that were on the z6 motor, does this mean they are going to work? Or are obd2 injectors still the same shaped clip but operate differently? Also, my main problem is the wiring for the intake manifold. Im having a really tough time figuring what goes to what.

 

ttt

 

anyone out there that has done this swap?

 

ttt i really need this

 

bump

 

lets hear some info on 3 wire to 2 wire IACV converting

 

yeha al you rock

 

help me

 

Do you have a Helms of any form? (downloaded or hardcopy)

Would some pics of my installed stock Z6 mani help? I doubt that the pics would reproduce the wire colors, though...(see first question)
