How hard is it to put a 98-spec B18c5 in a Del Sol? Wiring issues? What is involved?

Spade

If your asking like this.....you haven't researched enough and so my answer is YES.

Every B series motor has wiring issues unless you have an uncut harness and its not JDM.

A little harder than putting a D15 in it, a little easier than putting a smallblock Chevy in it. Do some research before you talk.

i thought for a del sol, b series wiring harness is a direct plug in (for b18b anyways) and that if your car wasnt equipped with vtec you will have to run 4 extra wires for the vtec selenoid. correct me if i'm wrong

If you have nothing positive to contribute to a thread, then by all means don't post in it please.

Anyways here you go as copied and patd from an old topic I posted:

B18C5 engine wiring into a 1992-1995 Civic/Del Sol:

IMO the USDM ITR swap is easier to swap in. I've done this swap 3 times already and it is 100% easy especially if you run a re-chipped P28 and even more so if you have a 1992 Civic or any 1992-1995 Si, VX, or EX with VTEC wires.

Here's what you'd need too do if you have a USDM ITR swap:

KEEP the ITR engine harness. Regardless of what others say the plugs all plug right in. This way you get to keep the newer ITR distributor and injectors, and there is no need to rewire anything. Again this is from experience, not hearsay.

You'll have a few extra plugs left over on the ITR harness because the ITR has a few extras that our Civics don't have, like ABS, etc. You vcan just hide the extra plugs.

Now there's a few different ways to get an ECU to work, and I'll list them from easiest to hardest:

1. Re-chipped P28. This will simply plug in. No need to wire up for a knock sensor because the P28 doesn't read for one. Better fuel, timing, VTEC x-over, and rev limiter = more power. OBD1 so no need at all to run any sort of extra sensors.

2. Kenji OBD2 jumper harness and JDM P73 ECU. I ran this on my motor for a while before the kenji ECU. You'll have to wire up a knock sensor wire and that's about it. Drawbacks are that this ECU has a 113-115 speed limiter and it doesn't make the power that the kenji-spec P28 does. ThisECU has OBD2 type plugs but IT RUNS AN OBD1 PROGRAM AND IT IS ONLY OBD2 IN PLUGS!!! I ran this ECU with no extra o2 sensor, no crank fluctuation bullshit, etc.

3. Jumper harness with USDM P73 ECU. Why? I wouldn't do this unless I was in Cali and it was necessary for smog bullshit. You'd have to wire up all the extra OBD2 bullshit and the ECU sucks compared to a re-chipped P28.

So that's for the USDM motors, but what about the JDM ITR swaps?

As Apexi-ITR has said the JDM harness can be used. It requires some stretching but it will work. If you must get the factory look then get any OBD2 type engine harness from any USDM B18C1 or B18C5 and then it will plug right in just like I said the USDM swap does.

As far as ECU stuff goes, really a P28 is the better choice again but you will need to add a VTEC oil pressure switch onto the JDM ITR motor because it doesn't have one and the P28 looks for one. Just pull an oil pressure switch from another VTEC motor - didn't you use a SOHC one Apexi-ITR?

Or you can run the jumper harness and O.E JDM P73 ECU. This will save you from having to add the oil pressure switch, but you'll have to add a knock sensor and this ECU still has the shitty speed limiter.

USDM ECU? But why?

That's about all I can think of right now. I run the kenji-spec P28 ECU in my 1992 CX hatchback and with this method and keeping the ITR engine harness I did not have to add one single wire at all! It was absolutely 100% plug and play!

End paste.

Here's some more info I posted a while back...

Begin paste:

If you own a 1992 Civic, or any 1993-1995 VX, Ex, or Si Civic then a B18C5 swap will be a 100% totally plug and play swap if you use a re-chipped P28 ECU.

I could tell you that it plugs in, but why not SHOW you?

Here's an OBD1 engine harness with TWO plugs for the distributor:



So here's proof in pictures that I have a B18C5 swap in my 1992 CX while retaining the B18C5 engine harness complete with it's newer, better distributor, injectors, etc.



And the strut towers with the B18C5 engine harness PLUGGED right in:

if you have a del sol vtec it bolts right in and there are no wiring issue's

Why even post if you cannot contribute 100% factula info?

If he has a Del Sol "S" model then he will need to wire a few things up depending on which ECU he uses.

If he sticks with a P28 and uses the ITR engine harness he'll still need to wire up a VTEC solenoid and the VTEc oil pressure switch.

Right now, I have the B18c5 in my 97 EK, I am running stock Type R ECU (BTW this is a 98 Spec B18c5)...

I am planning on changing the motor over to a ~94 Del Sol, can I use the Wiring harness that I have right now? it is basically the stock civic harness (1997) with the modifications for it to work for the B18c5...(OBD2)

Also, what shift linkage do I need for this motor in the Del Sol?

Thanks!!!

phantom_sol

del sol vtec (b16) shiftlinkage

fowler!

Exactly. They are different from the other b series linkages out there.

I have a p28 you just don't use a knock sensor. I post because I can *******.

...but who gioves a **** what you have if you cannot even post useful info?

It was already all laid out in explicit terms, then you chime in with "it's possible" basically so who cares?

It would seem that the only ******** in here are people who post vague-*** one-liners just to get their ppst count up rather than post useful info that actually pertains to the topic at hand.

B18c5-eh2, you gong to reynolds for the nopi drags?

A lot of people post just to argue, some post just to post. You can do anything anything you want to a car, people wire vtec to thier blinker for Goodness sake. Some of us (yourself included) try and tell them more of how it should be done than how it could be done.

Looking for you there,

Actually I used the USDM vtec solenoid off of a GSR.

I believe a SOHC vtec solenoid will work as well.
