i tried to get my car ready for the meet on sunday, but that didnt happen…i ran into harness problems.
I have a '95 ka24de and i have a harness form a '91-93 ka24.
i want to know what my options are , i want to get this car runing again.
The engine is installed and i dont want to have to pull it again to take the intake mani out and ill have to source a '91-93 distributor.
Is there any thing else i can do to make this harness work or i am better off trying (key word, trying!), to find an s14 OBD1 harness? i think my chances are slim…
my buddies at the shop sourced a harness from an s14. But the guy selling it wants 300$ …i said, we’ll see about that one first…
I want to know if that harness will fit, i was told that the loom (whatever that is?) wont fit into my s13 without mods…if the loom is the part that is supposed to pass thru the firewall, then ill drill a bigger hole…its easier than sorucing 4 diff. parts and changing the manifold.
91-93 tachometer or full cluster
91-93 DOHC distributor and ignition coil
91-93 none-hicas power steerting pump
91-93 power steering lines
91-93 engine harness
91-93 exhaust manifold
91-93 intake system and MAF
91-93 intake manifold if you want to keep emissions
EDITAndrew, you beat me to my post, but you posted this while i was writing this up…thank btw
So basically, the car wont run without doing those changes?
Now before i go any further, i still dont know what a “loom” is. I didnt see that word come up in anything of the other treads i read.
The car is sitting and waiting for parts and answers…
I need someone to answer me with a staright answer.
I either need to buy the MAF, injectors(cause apparently the injectors off my engine dont fit the clips on my '91-'93 harness i have), ingnition pack and disstributor, and '91-93 ECU.
OR
Can i use a harness off an s14? But again, why wont it work? becuase of this loom thing wont fit?
Im sorry, but im still lost about all this. Info is very little to what i need to be answered and its all scattered all over the place.
Now the only reason to switch my intake manifold (upper and lower as a whole? ) is that you only need to change the lower intake mani. because of emission purposes? if i were leave it and not use the 2 holes or whatever it is located on my '95 ka lower intake mani. can the car run well without it? will i have mad issues trying to pass etest?
i was also told that the top half of the intake manifold off my '95 ka flows better than the ones on the '91-93ka’s, this true for a fact?
aside from the MAF, disstributor and ingnition pack, i have eveyrthing else sorted out in terms of ps.steering, exhaust, tach, ait intake (im using the one off my SOHC for now). So the only thing left to figure out is what to with the injectors cause they dont fit the harness i have and the intake manifold…
i am sure this has been posted before. gotta search man. if the answers
are not on SON, check another forum. this swap has been done to death
all the answers are out there
Following the demise of my wife’s SOHC due to rod-knock, pours a 40oz I swapped a DOHC KA in it’s place. In this post, I will tell you how
YOU CAN TOO!
I cover how to swap a S13 DOHC motor into a SOHC equipped S13, as well as parts necessary.
Source parts needed for swap (full parts list is at bottom of post).
Ensure you have adequate tools, space, equipment, time and money to accomplish this.
Source a motorset.
Yoink old motor from chassis. You can unbolt the motor mounts from above or below. Guide the motor out, making sure it doesn’t damage
anything on it’s way out. I’d pull the tranny at the same time as well, in case you’re going to be utilizing the same transmission ,so that reinstallation will be much easier.
Remove A/C lines. You will have to get custom lines made if you want to keep A/C, or make a custom bracket for your SOHC compressor.
[OPTIONAL] Remove any other engine bay items like AIV, airbox, etc. and prepare engine bay to your liking. (clean, sand, paint, nothing, etc)
Move SOHC power steering lines over to driver’s side & install DOHC power steering reservoir -OR- install S13 DOHC power steering lines.
Replace SOHC throttle cable with DOHC throttle cable. Two bolts at the firewall behind the accelerator (and remove the accelerator to make life easier.
Pull SOHC engine harness. You can either cut it at the firewall, leave it intact and pull it thru the firewall (into the engine bay), or whatever is easiest for you. Don’t throw it away just yet - you may want extra wiring, or to keep the connectors for future use.
Install DOHC engine harness. Reverse of above.
If you’re doing a manual swap, NOW is the time to drill out the place for the clutch master cylinder, install it, and run the hardline down.
reinstall everything you took out to prep the engine bay, like AIV, airbox, cruise control, etc.
Prepare your new motor. This means whatever maintenance you’d like to perform on it before it goes in, i.e. water pump, vacuum line
replacement, thermostat, reseal oil pan, timing chain job, belts, etc. It’s about 11ty billion times easier working on an engine when it’s OUTSIDE of a car.
Slide your slick new DOHC KA into it’s new home. Again, watch your clearances. You don’t want to damage anything or scratch that fresh new paint, right? Make sure you attach your heater hoses during this step. It’ll make life MUCH easier.
After getting the tranny mount in and bolted down, tighten down the motor mounts. This is important, as your engine can sit cockeyed and still be tightened down at the motor mounts.
You’re getting close! Reinstall your clutch fan (or not if you have electric stuff), and install your radiator and fan shroud. Install your Upper and Lower radiator hoses at this time.
Start connecting the harness to the motor. Now is the time to do a clean job of installing the wiring.
Finish installing everything else, like intake piping, sparkplug wires, etc.
Your engine bay SHOULD be complete. Now it’s time to address swap wiring.
Wiring:
F’ing SIMPLE.
Locate the body harness (under dash harness that attached to the ECU) that attached to your old harness. Cut the old connector off (the one that attached to your SOHC harness) and attach your DOHC body harness connector. Just match the colors! There will be some wires left over. These are for the SOHC’s diagnostic plug, and are unnecessary. Please note: Your car will NOT be able to hook up to a CONSULT tool. To accomplish this, you must get a body harness with all the correct DOHC wiring. This is why we cut the body harness connector off, and not the engine harness connector.
I recommend using a soldering iron, shrink tubing and electrical tape as opposed to butt connectors. It makes for a much cleaner job, and a cleaner electrical signal.
You need to swap out your tach if you want one that works. No wiring is involved, but it must be done. Simply pull your combination meter (gauge cluster) and remove the three screws behind the tach. Lift and separate. Installation is reverse of removal.
You should also extend the wires that go to the PS line sensor and connect that to your subharness. It’s not necessary, but it’s a good
idea.
Parts needed:
S13 DOHC KA (or S14 KA with OBDI lower intake plenum, S13 DOHC distributor and S13 DOHC coil & others)
S13 DOHC engine harness & body harness connector.
S13 DOHC MAF, intake piping, coil, tachometer, power steering reservior and hoses (low pressure), throttle cable (and cruise cable if you have it.), engine-side brake booster vacuum hose, engine/transmission subharness (if swapping from automagic).
Optional: S13 DOHC power steering high pressure lines
A few sidenotes: S13 AIV system is same/same. Nothing needs changing there. For cruise control, the cable length is dependent on the motor. DOHC cruise control can’t use the SOHC cable without a weird custom bracket.
For my swap, I used a '95 KA, adjusted to behave like a '92. I used a '92 exhaust manifold, EGR tube, distributor, lower intake plenum, coil, and vacuum routing. To eliminate the secondary butterfly vacuum line, I pinched it and sealed it. I performed a fully stock swap. No EGR or AIV elimination, no intake or cams or otherwise.

PS. Please note that I did all this by searching for information on how to do it. I’d never previously swapped a motor before. Also, feel free to remind me of steps that I missed, info I left out or didn’t address, or other constructive criticism
Now the only reason to switch my intake manifold (upper and lower as a whole? ) is that you only need to change the lower intake mani. because of emission purposes? if i were leave it and not use the 2 holes or whatever it is located on my '95 ka lower intake mani. can the car run well without it? will i have mad issues trying to pass etest?
i was also told that the top half of the intake manifold off my '95 ka flows better than the ones on the '91-93ka’s, this true for a fact?

So the only thing left to figure out is what to with the injectors cause they dont fit the harness i have and the intake manifold…[/quote]
The 91-93 harness fits the 95 ka motor no problem. Injector clips not fitting makes no sense to me.
The 95 ka manifold has no butterfly’s that bassically the only difference. Yes just block off the EGR and don’t run a charcoal canister if you want to use the 95 manifold.
I need someone to answer me with a staright answer.
I either need to buy the MAF, injectors(cause apparently the injectors off my engine dont fit the clips on my '91-'93 harness i have), ingnition pack and disstributor, and '91-93 ECU.
Yes, you need MAF, ignition coil and ECU from a 91-93 car. The injectors however you don’t. I don’t understand why your injector clips don’t work, I’ve done many of these swaps and never ran into a problem like that.
andrew - thanks agian man for the help…ive been doing a lot more reading on ka-t.org as well.
As for the injectors not fitting, i was only going by what the guy at the shop said…the only reason i can think of it not working is if the injectors are SR ones or something? i didnt really check since i havent seen my car since the engine has been in since friday…
