Please give me a complete list of everything that needs to be changed. I have a '91 S13 with the original KA24DE in my car right now. I'm in the process of ripping it out as we speak. I have a '96 S14 KA24DE hanging in my garage waiting to be put it. But, exactly what has to be changed to make the swap complete? Is the wiring harness an OBD2, in both, the (91)S13 KA and (96)S14 KA?

All your help is appreciated.

Thanks alot,
-Jeremy.

 

pretty much just the distributor.
everything else is pretty much the same.
use the s13 harness, and all that.

or have taylor make you a harness using the s14 distributor, if you want a cleaner engine bay.

 

agreed to above.

swapping intake manifolds makes it easy too, but not required (id suggest it though unless you have a modded harness and/or know your way around the various sensors.

 

Would that be, just the bottom part of the intake manifold? Or the whole manifold?

 

Any real quick ball park price on a wiring harness from Taylor? Even an estimate would be great.

 

im guessing around 100$
maybe more, possible less.

 

I did this a few months ago. Look at it from the point of only swapping out the long block. Use all of the S13 stuff that you can. I used the S14 upper intake manifold on the S13 plenum, and it works great. Don't forget to swap the coolant temp sensors, too. If you use the S13 distributer, you can simply use the stock S13 harness. I'd also pull the S13 cams out before throwing the old motor away. If anything, they're worth a few bucks.

Give your engine bay a bath, while you're in there.

 

Thanks alot for your help. So thats everything? Even the little stuff that means alot?

Just wanting to make sure that I have everything perfect before I put in the new KA.

Thanks guys.

 

Update on the swap.

Well today (Coolcloo1019 & Jeffronismo) ripped the old KA out. For being the first time for all of us doing this. Without any guidance at all, I thought we did excellent!

Tomorrow, I'm going to cover everything up in the engine bay, and pressure wash the bay to clean it up a little. This weekend, I will switch the intake manifold, and bolt the tranny to the newer engine. Then, hopefully by sometime next week, I will have her running.

Quick question though. On my old KA('91), I have four aluminum vacuum (I'm guessing) lines that are sticking out just under the intake. On my newer ('96) KA I don't have those. BUT, on my new engine ('96) it has a bunch of vacuum lines and other misc. things on top on the intake manifold, in that area. I would like to know what I have to do with this. If you guys don't know what I'm talking about..Then I can get some picture's for you. Thanks for your help.

 

the 91-95 motors used an evap system (charcoal canister) that was mounted just to the driver side of the radiator on the radiator support. the 96-98 models that utilized OBD-II had the evap canister relocated in the rear of the car (directly behind the passenger tire/hidden by plastic shrouds), and it used one line coming to the front of the car for when it would purge the fuel vapors into the intake manifold. i'd suggest if you plan on keeping it to use the s13 upper and lower manifolds (much easier to swap out with the motor out anyways).

you can delete this out of your system and cap the lines and deal with a few check engine lights and a cleaner engine bay, but it doesnt really do much performance wise, and even though florida is becoming smog central, we dont have smog nazis yet so no hassles with anyone. (if you do decide to remove it, its best to not cap the line coming from the fuel tank (the vapor line)...its under some pressure at times, and its best to just direct it downward away from the car. if you cap it, you'll just have more of a pressure release when you go to fill up with gas as you release the gas filler cap).
