Wow, this swap is tough!

1st generation JDM B16A w/ p28 chipped ECU – 92 Civic CX Hatchback.

Here is the recent problem – I need to get this car running, any insight would kick ***.

I now have the o2 properly setup. All the wiring harnesses are connected and grounded properly. However the red wires with black stripes from the fuel injector harness I cannot figure where these wire go.

Here is the crazy part.



I was told to get a resistor box – like the one pictured above. I used one wire from the 12v power distribution connecter – pictured below with the red dot.



I connected ONLY one yellow wire form the 12v power dist. to the red power supply wire on the resistor box. Then I connected the four black wires from the resistor box to each red wire from the injector harness. The engine started right up, loud as hell since only the header was installed. The engine had a crazy idle, and was extremely rich. I mean about 70-80 psi. I drove around a little, drove like ****. Then I figured something was not hooked up right. However nothing changed, then later that night the car would not start.

Now I’ve figured out how-to (somewhat) setup the resistor box. However, I do not know what the hell to do with the four red wires coming from the fuel injector harness. The four red wires I cut off a female connecter that has one yellow wire coming from the plug.

Does anyone understand this?

Running an open header, could this be a part of the problem?

My fuel feed line has a slight leek due to the stupidity of STR’s fuel rail… Could this cause a problem? Gas is not dripping, just barley making it’s way through the line…

After work I’m going to Honda – I need to pick up some random bolts and crap. What Honda service manual should I get for the 1st gen. b16a?

Thanks.

I very helpful person wrote me an IM - He stated: <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">actually that swap is not too bad, just keep in mind that you have to make everything simulate a OBD1 car or engine. you do not need to do a resistor box. you are just adding more trouble for now to the mix. I would of just got OBD1 injectors first as those are meant for the ecu and car model. open header has nothing to do with the car starting but is just loud and maybe a loss in backpressure if you drive around like that. I would fix that fuel line problem. don't want to see all that work go up in flames.</TD></TR></TABLE>

He also told me to get injectors from a 94-95 integra, or 92-95 civic Si/ex or dx. I just want to make sure, will these fit on the jdm b16a harness?

Thanks.

Any other insight would be great, thanks.

I forgot to mention. This engine is very modified since it used to be turbo'd. The injectors are not stock. I have no idea where they are from, but they are much larger injectors.

EDIT: If I change the injectors to 99 Civic Si, where would the red wires coming from the injectors go? Would I need to modify the conectors, if so what should I use?

Do you know if they are saturated or peak/hold?

Running into enough problems with this swap???

Nope, I ran open header for like 2 days on test drives and stuff, then took it on a ~5 mile drive to the muffler shop to have an exhaust made.

for the toughest swap ever!

Yup, I will be going to Dan Fast for the exhaust!

Yes, running into a lot of problems...

I leaving work in a few, I need someones help! Please...

If I don't get this started tonight, oh man. Any help would be great. I've gotten a few ideas to try, but more the better.

Have you tried to run it without the resistor box?

976

Yes. It will not get power to the injectors without the resistor box. I think I might have to try the stock cx injector. I will need to convert the injector harness. Most likey it won't work, but I guess I have to give it a try.

Honda wants $503 for a set of 92 Si injectors. Well, that's out...

i would of gotten some obd1 injectors, obd1 gsr engine harness.
and you would be set so long the harness plugs in on the alternator.

Blown90hatcH

Did you try it by leaving your stock cx injector wiring in? Before the resistor box install? It is hard to help when you dont know what injectors you have.

I just stuck in the stock cx injectors. I going to wire up the stock 2p connectors. Now where the hell can the red wires with the black stripe go - four of these wires, each 2p connector has one coming from each injector.

The spark plugs were covered in gas. Could this be the cause why it didn't seem to fire?

Definately. The plugs seem to be wired incorrectly and it is dumping fuel. What is the FP?

Well, I should have listened to some of you guys to begin with – however, it’s very hard to find the problem when you have a mixed matched motor becoming a hybrid.

Well, it started. And I drove it out of my friend’s garage last night. I had use the stock cx ECU, the chipped p28 ran a little richer, I need to knock it down somewhat since the fuel PSI is 70-80.

I take it the CEL that comes on is the o2 – hence the cx has one wire, instead of four – which I now have installed. Plus the check engine light only comes on when o2 is warmed up.

The knock sensor should not come on until’ I got above 5K RPMS; my ears will not be able to handle the open header at those RPM’s. So I didn’t check.

To get it to run, I needed to take the fuel injectors, and 2p connectors off my D15 motor. I had to wire them into the harness. I then had to rewire the harness that I cut apart to connect to the damn resistor box. I had a brain storm, people said it wouldn’t work, but I tried it and it did. I connected the four red wires with black stripe to the 12v power supply connector – the one stranded wire coming from there. What do you know, that was it the whole time.

I also needed a 92 GSR throttle cable.

I would like to say that from my experience people have been very helpful here like always. The Honda dealership parts guy was helpful; too bad NOTHING is ever in stock!

Thanks for all the help guys. I still got high PSI to deal with and some other crap to test and tune. Other than that it drives and sounds good.

- Since on the subject, what should the stock fuel pressure be at?

Thanks,

Stock B16A fp should be at 38psi at idle.

I have mine turned down to 32psi at idle. I have the mugen program and an upgraded fuel pump. LEAN THAT BITCH OUT!

Sorry I haven't been able to help you out that much, I just have no idea about any of the wiring. Like I told you before I didn't ahve anything to do with that part of my swap.

WAFFLES: You were one of my biggest helpers!!!

If it wasn't for you I would not have tried the stock injectors...

Cool...thanks....anytime...blah blah blah.
