Ka Swaps: Who Has One Working, Who Is Still Working On It? Options

[200sxkitcar]

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.

[asparagus]

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

[200sxkitcar]

nice

[EternalSwap]

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

[TechDaddy]

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

[TechDaddy]

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!
