There is a decent amount of info on here that is kinda mixed up, Im looking to get it straightened out. First off, could everybody who is actively working/successfully done post up their info? Such as:

Garrett76, KA-DE, into MK2, runs

Phillip, KA-DE, MK2, runs

Rage, ?, MK1.5(?), runs

Worr20, Dohc ka, mk1, 'flys' lol!

TechDaddy, KA-DE, MK2, runs, FS

Altyman, ?, MK1.5, work in progress

Asparagus, KA24DE, MK1, Runs

Firestarter, KA-DE, MK1, work in progress

Silvia Love, KA-E, MK1, work in progress

Sinestro, KA?, ?, work in progress

Mr.LonelyS12, KA-DE, MK1, work in progress

Dangina, ???, work in progress

Eternal Newbie, KA24DE, MK1, work in progress...

Arro, KA24DE, Mk1, runs

and so on. This way we can network a bit better and get some comprehensive info on wiring needs. Phillip's thread is great, I would like to do something similar, but more extensively with a how-to and more pics, geared towards MK1/1.5. Some questions will come up and I would like to know who to ask, if no one minds lol. I don't think it will be too hard tho, except the car we'll be working with may have a pretty messed up harness from the previous owner's attempts.

Thanks everybody!

Rage's car runs, as for EternalNewbie he got his upper harness re-done by heatw and doesn't run yet. Mine should be going in within the next couple weeks, and it's a turbo MK1 and I plan on using the stock trans mount with the KA C tranny. I'll provide info and pics when the time comes, and probably ask a ton of questions.

Dude, totally forgot about your car lol. I will update The hardware choices with the trans I'm still trying to sort out exactly, but the wiring is where the real question lies.

Haha, I didn't mind that I wasn't on the list. But yeah, the wiring is where the question really lies. That's what stopped a few from getting theirs to run already.

worr20, Dohc ka, mk1, flys

nice

Me me! KA24DE. Stock trans bracket can be modified (slotted) to work (jankily) with the stock shit. I'm waiting for my polyeurethra to fully dry. I'm going to be running Taurus fans.

mk1 20e going ka-e...in progress. i still need to source a transmission

Mine runs great but I am looking to sell soon. I am still up to any questions I might be able to answer. Good luck! My advice, Get a factory service manual for both and make your life alot easier! See my profile for specs.

MK1.5 in process. IF budget allows it should hit the street by the end of the summer. It should start this spring, or maybe before. That is if the engine is still capable of running even after the sleeping it has gone through...

base model MK1, ka24de. ^ same plans as me.

just got the engine last month haven't started yet - been keeping an eye on asparagus's:)

You guys that are doing the KA swap are doing it the same way as the SR and CA swaps aren't you?

Only reason I ask is coz I saw a post where someone is taking the whole dash etc out of his car to try to figure out how to do the wiring etc. It makes me think that maybe some people are trying to find equivalent wires in the s12. Just that these swaps aren't done like that for the wiring, its a crazy way to go about it if your trying to do it that way and makes it way to complicated.

What you do is just treat the CA SR or KA engine/ECU loom as one integral unit and wire up (separate to the s12 stuff) relays to run the main components and then wire the relays to triggers in the s12 system like the main igntion on wire and start wire etc. (I'm sure you successful guys have done that.)

I've seen on other forums a while back where SR's and CA's are swapped into KA s13's. s13 to s13 motor swap is totally different to an s13 motor to s12 swap.

That is actually how heatw set up my harness.

The reason I take the whole thing off is beacause the wire diagrams won't fit with the car... starter wire starts on "on", can't find the fuel pump wire and so on... I had ran custom wires, with custom switches that could have got the engine running, but I didn't want that so I'll do it "properly" instead.

Plus I cannot register the car with the body in it's current shape, so I'll need to strip it anyway for the body work.

I haven't found any wiring diagram that would fit my MK1.5. Maybe if I would have found a FSM, I could have done it without stripping the whole interior, but I needed to do it for the body work anyway...

Okay so there is no shop manual for the 1.5 cars??

Running a mostly separate wiring system for an engine swap from a totally differently wired car is the proper way to do it, otherwise you'd have to take out a number of complete harnesses uncover them and trace all the wires and rewire them, which would end up a mess and a nightmare.

Ka to s12 is exactly the same principle as SR or CA to s12, no different. CA and SR are from an s13 so is the KA.When they drop a SR or CA into an s13 they work from the 2 or three main connectors that connect the rest of the car electrics into the integral engine wiring harness. They are lucky in that all they have to do is swap a few wires around and its done.

In the case of the s12, (or other different car) what you do is identify all the wires you need in those (entry) connector/plugs and wire 'new' relays to them. Then they are triggered by a few wires from the other car e.g. ignition on etc. and that's it. You don't try and blend 2 totally different systems.

You need to find s12 wiring colours for things like: ignition on, starter, fuel pump etc.

With the ignition on and starter wires, you can just pop out the ignition switch and it has small markings on the back that shows you which wire is which.

For the fuel pump etc you might have to trace the wire through if there is no record to look up for the colour. I'd find the relay for the fuel pump and note all the colours, then go to the fuel pump and note all the colours, there should only be one wire between the 2 that matches.

Don't try and use any of the existing s12 engine relays for the KA, just wire your own.

Yea I'm not concerned too much about the wiring, as the car's owner has a update 86 FSM with the MK1.5 info. The plan is to use the KA EFI harness, as you would in any swap, and just source which necessary power/ground/fuel pump type feeds are needed out of the main harness. The scope of this particular thread is just laying some groundwork as to whom has swapped, level of completion, car version, etc. I'm not really concerned much about the wiring, its just good to know who has what and what they know

Gerry, I understand exactly what you mean. Unfortunately some who are less experienced have not fully understood what is actually needed and what you don't want to mess with, and how its simpler than what it may look, and how necessary it is to have correct wiring diagrams.

I'm looking to end all that. With pic by pic type of guide, wires will vary, but at least you will know what to look for, thats the idea eventually. We're in learning/gathering mode right now.

KA24DE-t going into mk1, not running, going to stand alone fuel and spark management

Amen brother![ That is exactly what I did. Soooooo much easier. S12 chassis wiring and engine wiring should be viewed as seperate entities. Makes things simple and far less complicated. It helps to have both factoy service manuals

I don't know if an FSM exists for the MK1.5 honestly... I actually started with custom relays and everything (as you can see in my thread) but got worried about the looks, and how to hide it to the inspection (which I will have to pass to got the car on the street). I'm not a total noob, I might not know as much stuff as you do, but I know I'm not taking the easy route at all and this really is my choice, mainly for aesthetic reasons!

mk1.5 fsm does exist and i have it ive been trying to figure out a way to get that book into a pdf format. the books title is "1986 200sx mid year change" but i have an mk1 i think b/c it was made in january of 86 but to be honest there is not that much different from the mk1 wiring colors

Altyman sorry I come across hard, its cause I'm an old bastard which makes me pretty direct. I mean well help wise.

I understand that inspections might make it hard.

I actually stripped my car to a bare shell to restore it, (I mean completely bare so I know what a pain it is to put everything back together again).

I don't know that much otherwise I might be able to do it another way. Its just that with what I do know I know I couldn't combine two different systems. If you could get access to one of the 1.5 factory manuals it would make life so much easier I reckon.

mine is a ka24de swap is in the 88 se model. still in slow progress

What hapened to the V6? Seems a shame and a pain to go from 3L V6 to 2.4L I-4 power. You planning on going turbo?

yea the s12 timing belt broke, i bought a d21 truck with the v6 and blew the bottom end. so i guess i'm done with the vg30e for now. i thought about turbo, lately i've been leaning toards a carb setup. but for now just na will be enough, the stock factory rating is only a 5hp, 6tq diffrence, but its a newer design and i already have another to rebuild in my basement. i know how i drive and i thought a ka swap would be cheap but my ka swap is turning in to the most expensive

have you thought about rebuilding the v6? time consuming yes but it would be well worth it i would think

No problem, I'm not frustrated at all or anything!

Updated, thanks again everybody for the responses.

Tomorrow 200sxfrankenstien and I will be getting together to take a look at his car, and for me to take some pics. I will probably also borrow his mid-year update FSM and scan some stuff, probably forward it to Julie or Premo and have them host it. I don't know how to use my scanner yet lol, nor do I know the procedure for conversion to Adobe PDF file, but I will learn, and I will probably start a thread about it in 'Coffee shop' section if anyone is familiar with the PDF stuff feel free to post up your knowledge

where did the mk1 fsm's go? none of them work. i need to find ca20e engine compartment and ecu wiring diagrams.

well i have been shot down by silviagod i emailed him to ask approx how much it would cost to ship a kit to the usa and he replied that he does not ship the kits im so dissappointed

so yea my ka24de swap is going in the se model, and i am going from a automatic to a standard also, i should of been done by now but because of punk kids i'm still workin on it. first i got the ka deal and got ripped off cause although i said what i wanted i got everything but the transmission and mass air sensor sent to me, and after searching for awile i thought i had a couple of leads here but no one responded back, i finaly found a ka transmission at a local junkyard that cost 300 bucks. that with the standard ca20 xe transmission that i allready got for 300 bucks means that i spent 600 bucks just for a hybrid transmission that i could bolt on to the 600 dollar ka, so for 1200 i could of got a new car. that aside this swap should of been easy, but no the v6 crossmember sits the motor to far foward, and the v6 radiator has no cap, this i temporarily solved with a in-line cap adapter from the summit catolog. the mass air sensor i found was from a ka powered altima, still not sure if it will work, but i guess it should. now my setback is the drive shaft, from what i read some where on here the only one i can use is one from a 88 standard model, as all the earlyer driveshafts have the carrier bearings are in diffrent spots. i did get lucky in some ways, as the holes are all there for a auto to manual swap so far, and most of the clutch stuff i got out off my old truck. it will be like a totaly diffrent car when i'm done. i just like the idea of useing nissan's 'bastard' motor in there 'forgotten' car

in the "ka24de in mk1" topic i put a link in there for a 1986 mk1 fsm go check it out

the links dont work

the second link takes you to the webpage that i found the link in. its about half way down

I just wanted to post to show my car. I have read stuff sayin that noone has a KAT. I have one but I had to move to Az for UTI. Imma tow it out here and finish it. I just had to finish wiring

No shit, I was THIS close to going to UTI in AZ, but then I decided to stay in SoCal...

Sinestro, for drive shafts I used the front half S13 KA 5-sp and rear origional 84 CA18ET.

anyone know the differences in mk1 xe's rear part of the driveshaft to the turbo's. obviously r180-r200. any lenght or bolting differences. can the ca20e rear bolt to s13 front?

Go to a junkyard and try it.

Then take the front part of the S13 one home, put it in your pants and say you have a big dick

i'm still looking for a standard driveshaft, i know i need the 88' model years but i'm not sure if the standard se and the standard xe from that year was the same, i imagine it is? i am using the bellhouse swap method so the gearbox was from a ca20 xe model that was in the junkyard, as for a 240 driveshaft around me that car is nonexistant. i still have 'assembly' to complete but now its winter in new york and i am doing this all in the middle of my driveway. my wiring i asume should be similar to the mk2 wiring but it would seem that more of you are in mk1's

Mine runs great!

updates?

I just took at cut the three plugs on the ka engine harness that connect the engine harness to the rest of the world, then one by one ran those wires to suitable locations on the s12 wiring system, and it fired right up, swaps not a big deal if you have detailed wireing diagrams for both the engine your using and the car its going into. Mines running: KA24ET, 450cc/min injectors, megasquirt II, custom exhaust, custom intercooler, log type manifold, t3/t4 hybrid turbo, external wastegate, and a buch of other fun stuff.

oh, and the stock ca driveshaft works fine, all you have to do is when the ka is out of the car, knock the engine mount brackets towards the rear of the engine 2 inches, then flip the trans crosmember around and she'll bolt right in, i spaced my drivers side mount so my manifold/turbo was more out of the way of the master cylender (i'm top mount)

ok my progress has been limited due to weather, but i've been rebuilding the hybrid ka/ca transmisssion in my basement, i've been taking pictures of everything along the way step by step, but on a crapy one time camera hopefully the pictures will turn out well. after development of the pictures i will figure out a way to post them up here. the bellhouse swap alone is somewhat easey for me, but only cause i had it apart so, long i ran into my own problems along the way and took some of the wrong parts apart, but i figgured it out and will show my solutions so that the info is easyer to find and understand, i belive all the c style transmissions to be the same so this info will not only help the ka guys but anyone haveing c style transmission problems

it might take me a little wile to get my pictures organized and posted, but in the meantime if anyone is having transmission problems or questions feal free to ask me and i'll try to help if i can

you did what to the motor mounts? so what car do you have, mk1 or mk2? what wires did you run where? im planning on doing the same setup like keith and his ca18det wire up. i wanna wire my engine harness seperate from the main harness. i was looking at both wiring diagrams and i think i see what wires would go where if i were to wire it like yours.
someone correct me if im wrong but looking at the mk1 ca20e wiring diagram, it looks like the ecu and fuel pump share the same relay.

Take me off the list.

Sorry guys

Ok, well my S12 is ready for a my new motor.
I got my S13 in the garage sitting on stands and I'm ready to take out the KA-DE.
What exactly do I need to take out that would need to be in the S12. Sorry that I'm not searching but wth!? Come'on. Anyways yeah... I'm finally going to have the time to get this motor in the S12 and running. So... what's up!?

Motor harness, intake/exhaust, motor , probably ps hoses??, ecu, maybe driveshaft (not sure about SRA), motor mounts, alternator plug...

Just got my KADE with my S13 purchase... It will be going up on an engine stand and going through some rebuilding ish before it gets put in the 12.

So, have parts. That's my progress. lol

well, dont know if my name should be added to the list or not, but i am workin on putting a KA24DE/S into my s12. gonna megasquirt it right off the bat so i dont have as much of a wiring nightmare as most of you guys since its going into a mk1.5. right now, i am just piecing together all the parts i am going to need so it not really underway yet. Gonna try to stick with the ka tranny. any advice or help or whatever is appreciated.

bought a ka24e today going into a mkii next weekend, going to be turbo'd as soon as i get some more funds
