Im swapping my d15b7 for a d15b7 w/mini me. It is a z6 head. The mini me is obd1 but the b7 i swapped out is obd0, i need to know if i cut the plug off the z6 distributor (obd1) and splice them with obd0 connectors. Will this work? I do not want to use the stock b7 distributor, i want to use the z6 instead.

 

hmm, guess nobody knows.

 

just a question:

how are you planning on running SOHC vtec in an OBD0 setup? No stock ecu's will work. Most people convert to OBD1. somebody may be able to give you a better answer though

 

You can't run a SOHC VTEC on OBD0 without getting a chipped ECU.

Go OBD1.

By the way, OBD0 dizzys have 18 teeth crank position gears and OBD1 dizzys have 24. They WILL throw a code and land you in limp mode. I know from experience (ran obd1 dizzy on LS while waiting for correct dizzy).

 

im going to be using a p28, i have the wiring harness for the p28 with all the wiring, and im splicing the wires together. Or unless you have a VERY cost effective way other than this let me know, i am doing this for a friend who has NO money.

 

Buy the Rywire harness from rywire.com and you wont have to splice a whole harness just a few wires.

 

p28 is an OBD1 ECU... I don't understand why you are trying to convert from OBD1 to OBD0.. please explain

 

yes, i understand that. This is a obd0 motor, it has a mini me swap on it. Its a z6 head, but a b7 bottom end.

 

yeah you said that..

it's an OBD0 bottom end with an OBD1 top end and computer... why are you trying to convert the motor to OBD0??? convert the car to OBD1 instead. That way vtec will work and then using the z6 head makes sense...

^^ listen to this guy

 

Converting cost more.

 

costs more than what?? buying an OBD0 ECU and distributor?

I guess you don't really care if vtec works?

nevermind. just read your age on your profile

 

Everyone just stop.

Do NOT splice into your wiring harness to convert to OBD1. I've done this. Do you know what happens if you miss 1 wire? Hours, upon HOURS of troubleshooting. I had fudge 2 wires and it costed me a full harness (engine fire). It was really not worth it concidering Rywire makes kits for 150$. And I make similar kits for less (~100$).

Do the PROPER conversion, you WILL thank yourself later and your friend will too buy not having a butchered wiring harness.

Buy the way, engine obds don't mean anything. I've ran obd2 engines on obd0 wiring harnesses, vice versa. I've mixed and matched more engines/parts/wiring then alot of people on here. Trust me when I say this, buy a kit, you will save yourself 10 hours of soldering and troubleshooting at least.

Tell your friend not to upgrade or mod if he's too broke to do it the right way.

 

I disagree. OBD Does mean something but I think it may be a very misunderstood part of an engine swap. It's that crazy grey area called wiring that everyone seems to run from.

OBD means On Board Diagnostics and refers to the computer only. Engines are not OBD. Engines can come in an OBD configuration and by this I mean the sensors installed on the engine.

I dont think splicing wires is that difficult. I've personally converted 3 CRX's to OBD1 by splicing OBD1 plugs onto the harness. If you managed to burn your car down in the works, then it was a matter of carelessness. It really is quite simple if you just stop and examine the wire diagrams for a minute before you start cutting. And 1 wire at a time usually helps, not to mention double checking the color of the wires that you are splicing together. If you are still unsure, then try a continuity test prior to turning on the power.

 

Nevermind, the motor is in and we are using the z6 distributor and splicing the obd1 connectors to obd0 connectors. We are using stock pm6 ecu and running a rpm switch for vtec. I dont have to worry about wiring at all.

just tell your friend to forget the project and get a new car, if ur gonna respond like that. modifying cars is not a cheap hobby. if you got no money, then don't do it!

Actually, splicing wires is the only way I have EVER done an OBDI converion. And you know what? I've NEVER had a problem. Doing it this way has saved me countless hundreds of dollars when you consider all the 1988-1991 Civics/CRXs that I have owned at various times throughout the last several years. Of course, I could have made my own adaptor harnesses. But I actually prefer this setup to adaptor harnesses. It's just SO much cleaner. You don't have that extra set of plugs with associated wire down there by the ECU that you have to somehow find a place to tuck it. And I NEVER have to worry that something could be damaged if a passenger decides to stomp their foot in the wrong place.

Thanks for putting another hackjob on the road.

Ya. After I fixed mine I also did my brothers. I didn't like doing it that way. Because when my B16 died and I wanted to toss in an OBD0 LS and keep it all OBD0 I couldn't go back and it sucked. OBD1 dizzys are alot more expensive then the OBD0 which you can find in so many junkyards around here.

Different strokes for different folks. I like no modding my wiring harness as much as possible so I can always go back to stock if need be.
