Engine Swap

I have a 91' honda civic dx (non-vtec) 1.5l. I want to swap it with a 95' honda civic 1.6l vtec engine. I have the vtec computer for the new engine and also a conversion kit as well.

search.

And when you're done w/ that, don't come back and say "The search didn't work"... search some more.

Been covered dozens of times, i did it, and I had multiple sources to choose from.

Whats the question again? I missed it in the first post. Sounded more like a statement to me than a question.

Tony, I see your point... there was no question.. that makes this a... Hopes and Dreams thread?

If that's the case, I have nothing to say here.

If that ISN'T the case.. I still suggest the OP Ask Jeeves (http://www.askjeeves.com), he knows all.

Tony, I see your point... there was no question.. that makes this a... Hopes and Dreams thread?

If that's the case, I have a 1989 Honda Civic DX Sedan, 1.5 liter, port and polish, 3 angle valve grind, header, intake, full exhaust, lightened 240 lbs. I want to swap it with the J32 from a Honda Accord. I have nothing for this swap.

If that ISN'T the case.. I still suggest the OP Ask Jeeves (http://www.askjeeves.com), he knows all.

you do know that every thread you post in a thread you jacking it and making it about you :nono:

to the OP...what's your question?

I have a 91' honda civic dx (non-vtec) 1.5l. I want to swap it with a 95' honda civic 1.6l vtec engine. I have the vtec computer for the new engine and also a conversion kit as well. And i also have the engine to complete the swap and just dont know how the wiring is going to work can someone help?

Ok, so the question is: What wiring do I need to do to install a D16Z6 in my car with a conversion harness?

Now my question is: What kind of conversion harness did you get that didn't come with instructions?

I ordered a Boomslang OBD0-OBD1 MPFI conversion harness for one of my hatches. It came with instructions, which are also easy to find online, and tells you exactly what all needs to be done. Ofcourse, the way I am, I modified it a little more than they did and I don't have to run as many wires back to the ECU harness as their instructions call for.

you do know that every thread you post in a thread you jacking it and making it about you :nono:

Obviously, you didn't note the sarcasm in that post... nor did you notice the agreement w/ Tony that there was never a question asked. Good eye, my friend.

OP - The instructions for most harnesses from reputable companies are available on their websites. You may also be able to find a copy of then by using Google (http://www.google.com).

Obviously, you didn't note the sarcasm in that post... nor did you notice the agreement w/ Tony that there was never a question asked. Good eye, my friend.

i type the truth:smooch:

My question is how do i complete the swap. I already have the conversion kit obdo to obd 1, d16z6 engine and also the vtec computer. I will also need to convert from dpfi to mpfi. What steps do i take, and where do i begin. Please reply.

The first one contains specific info on the z6 swap.

Since you have a conversion harness you really only need to do link 2 and 3, which are the same thing, the mpfi swap. You will need to redo your distributor wiring as well. The first link just has tips on getting the engine into the car, like which mounts to use etc.

Ok, I was taking up for you before, but now you go and create another thread asking the same question you finally asked in your other thread?

EDIT: Ok, look, it merged right into the old thread flawlessly. Don't create new threads asking the same question. If you want help, you will have to help us help you when we ask a simple question.

You still didn't answer my question: What harness did you get and why do you not have instructions with it?

If you want a DPFI to MPFI How-to, I just recently did a How-to on it, with pictures, showing a few different ways to go about doing the swap. Check the FAQ...which I also just recently went through and made it easier for noobs to look through.

I didn't get instructions with my conversion kit and its for converting my car from obd0 to obd1. That's why I purchased it in the beginning. My engine harness won't connect to the car harness either, how should I go about that.

Who made the kit? I wasn't asking what kind of kit it was, that was pretty obvious.

Please don't tell me it was an eBay special with hot glue holding the wires to the clip.

We can give you a general idea on what needs to be done, but we can't tell you where to connect the wires on your kit.

Yes it was purchased on ebay, I don't recall seeing glue.

i was told by everyone not to buy a conversion kit off ebay...

Say I have the correct conversion kit. Where do I begin?

That is one of the few things I would never get off ebay, its worth the extra money to get a good named harness like Rywire or Boomslang.

First thing I would do, is try to contact the person you got it off of and see if they can give you some instructions on what wires are what.

But seperate from the harness, you will need to do a MPFI swap on the wires: run the 2 extra wires for the 2 extra injectors, swap the outside wires on the TPS sensor along with extending them, run the 2 extra wires from the distributor, and figure out if you are installing a resistor box or not. Check the FAQ, I recently did a how-to on the MPFI swap and should have covered most of your questions on it.

Along with the MPFI stuff you will also need to run wires for your Vtec solenoid and oil pressure switch, and wires for a 4 wire o2 sensor.

Also, on the D16Z6, the MAP sensor is on the throttle body instead of the fire wall, along with the "purge" solenoid. These 2 sensors you can just extend the wires and change the plug on the Purge solenoid....or just extend the MAP wires and leave the other one.

From what year and model do I get the resistor box from. My car is a 91 honda civic dx. d15 (dpfi) and im going to swap it with a 92-95 vtec (mpfi) d16z6? I saw a resistor box on ebay... 88-91 Civic Crx SI HF Injector Resistor box Mpfi, should i get this one. The d16z6 engine going into the car already has the harness, intake manifold, throttle body. How do I go about the 2 main harness conectors on the car to connect to the 2 main connectors that are on the engine (d16z6).

If you use the obd1 injectors don't use a resistor box, the injectors dont need them.

91 honda civic dx swap

Im still stuck the big main harness plug on the car is different from the one on the engine harness going into the car.

I think I pretty much have it down my question is how do the car main harness plugs connect to the main ones on the engine there different.

You should be using the engine harness for your car, so you don't have these issues.

Get the plugs from the car you took the harness from, or get the harness that goes to a 91 DX.

Ok, I was able to get and print out the steps for converting to mpfi for (dummies). I want to be certain that the information you guys are giving is what is correct because I will be passing it to my brother he's doing the swap. D16z6 engine is complete, what things do leave on and what do take off. I've confused do I use a conversion harness or not? Do I use the harness from the d15 and also use the harness from the d16z6 and grab the harness for the injectors and then complete the wiring is the correct?

Follow the simplified MPFI swap by Tony.

Before you put the engine in the car, make sure you have the DX engine harness wired up to the D16Z6, with the injector harness already wired in and the Vtec wiring already done. Once you're done w/ all that, you can insert the engine, that should be pretty straightforward... after that, connect the engine harness to the chassis harness, and plug in the ECU. Connect your battery, done.

It's not nearly as easy as I just made it sound, but damn, it's not that hard either.

Do you know someone who might have the instructions for converting obdo to obd1 a diagram or a script that I can follow for the wiring. What is wrong with buying a conversion kit from ebay?

Thanks to everyone who has been helping me on this. Do you know someone who might have the instructions for converting obdo to obd1 a diagram, color scheme with instructions or a script that I can follow for the wiring. What is wrong with buying a conversion kit from ebay? Am I supposed to use the wiring on the d16z6 injectors on with the dx harness is this correct. I would like to get all my questions answered on one page thats all.

The reason why we've asked you to contact the person you bought it from is because each harness is going to use different color codes. You need the diagram from the guy you bought it from if you want the correct color codes.

and some things shuoldn't be bought on ebay...i just had a bad experience with Rywire (took 3 weeks to send my part) buy i bought an obd0 to obd1 harness from Blue Ridge Motorsports...i paid $75 overnighted to me (mostly b/c i'm a couple hours from them)

Ok, here you go:

On the D16Z6 Engine harness, you are going to harvest the complete fuel injector wiring, including the little plug with all the yellow/black wires on it. Just unloom the thing with a razor and pull this wiring out. Its relatively simple.

You will also want to get the plug for the Vtec-2 plugs there: 1 1 wire plug 1 2 wire plug. And you will need to get the plug for the o2 sensor, its a 4 wire plug.

Who ever is doing this swap will end up adding these wires and plugs into your stock harness. Doesn't matter what swap you are doing, you always stick with your stock engine harness and just modify it however you need to.

The problem with buying a conversion harness off ebay is this right here: You have no idea what color wires go to what. I can give you Boomslang's instructions, but I don't think it will really help you on wire colors. It will help you understand more of what you need to do on the OBD0-OBD1 swap though.

Simply go to www.boomslang.us and click Resources. This is the harness I got and it was excellent, great instructions, well made and no issues anywhere on it. It was a little pricier than others, but something as important as my ECU, I'll spend the extra cash.

Also, I have already told you once, don't make new threads asking the same questions you are asking in here. It helps no one when you do that because they won't see what else is going on.

Tony,

Do I need a resistor box? Im not sure if the d16z6 are high impedance injectors. I was told that I wouldn't need one.

You wont.

NO if:

They came from the Z6, or anything OBD-1 or OBD2A/B AND from a HondaYES if:

You're not sure where they came from, or what OBD they are, OR if they came from an OBD-0 (non OBD) Honda engine.Some injector tips:

Always go with the car you got them from... if it has one, use one.
If you're unsure, use one anyway, it won't hurt.
NEVER mix and match. Don't use 2 that need it and 2 that don't.
DSM injectors, if you ever use them, some use it, some don't. Never just assume you don't need it. Always assume you will.
Replace your lower injector seals, even if you don't think they need to be... you can't easily test for a vacuum leak under load.

Where can I buy a really good conversion harness with instructions?

www.BlueridgeMotorsports.com
i got mine for $75 shipped and it arrived the next day (i'm like 3hrs from them so it may be different for you)

and also try www.Rywire.com
they took 3 weeks to ship my distributor harness though

Boomslang is a great harness as well, its the harness I have for mine, well made and great instructions, it will answer all your questions.

Where can i find a b16a3 intake manifold and a ecu ecm p30-000 ive looked everywhere. Does anyone know someone that might have these parts for sale if so please reply.

why do you necessarily need an a3 im? search the market place over on H-T yet?

does anyone know where i can find a b16a3 intake manifold and a ecu ecm p30-000 i need them for the referee.

Does anyone have or know someone who might have a 95' del sol b16a3 intake manifold and a ecu ecm p30-000 for sale. please reply.

looked on H-T yet?

Honda tech yes. I need a b16a3 intake manifold and a ecu p30-a00 I have a civic type-r intake manifold and a ecu p30 obd1 anyone interested please reply.
