Ca20e To Ka24de

Nitro789 · 11:40:24 PM / 18-Dec-08

I am thinking about going for a KA24 swap. Do I need to fab motor mounts? i looked around on here and cant find it does it bolt right in?

rage · 01:21:39 AM / 19-Dec-08

motor mounts no, just use 240sx ones

trans mount, maybe

k i think I will do that and use the KA bell housing on the trany i have now

Do you have the C trans? I see you're an 86, so it's up in the air until you tell us. If you have the C trans, then yes you can just swap bellhousings and be done with it. But running the KA trans means you get a closer shift reach Also, if you DO have the C trans, swapping to the complete KA trans isn't hard, you just have to slot some holes.

It's the earlier S12's with the B trans that have to custom make a trans mount.

So, if I have an 86 Mk1 CA20E, I'd have a B-series tranny right?

Arro · 02:14:24 PM / 20-Dec-08

Maybe, maybe not.. the 1986 cars are a mid-change, some of them are Mark I, some are Mark II... so some of them will have the B transmission, some will have the C trans.

If you want to know which you have, take off your center console and take a pic of the shifter.

Also, there should be a little plate on your firewall with a bunch of numbers on it, one should be the transmission code which will end in either B or C if IIRC.

or just look at the door panel and engine valve cover.

any 86 car after the 4-5th month of production is a MKII any car before is a MK1.5

4/86

any S12 with a silver valve cover is a C tranny.

any S12 with a black valve cover is a B tranny

i think thats right info not sure...

rage · 01:57:23 PM / 21-Dec-08

yeah my MK1.5 originally came with a B tranny

if your mk1 with b trans just use the b trans with ka housing. all you need to do is swap the main bearing out. then no hastle at all, no driveshafts, no cutting, no worries.

my car has a silver top but the door says 2/86? does this mean I have a b trans? and if so what should I do for my ka swap?

Arro · 06:30:19 AM / 23-Dec-08

Silver top, usually is a C trans. Makes the swap easier.

Nitro789 · 02:26:11 PM / 23-Dec-08

so should I use the ka bellhousing on the c trans? or just use the ka tranny? Which is easier/ more beneficial?

Arro · 02:49:54 PM / 23-Dec-08

It would be easier to use the KA bellhousing on the C trans, but the advantage of a closer reach would be had with the KA trans.

Wilkie · 04:09:33 PM / 23-Dec-08

k...haven't had a chance to look in my door, but I know my engine was swapped at some point before I bought it for another CA20E. This one is a silver top, but I don't know if the tranny was swapped too. :S

fyneyoungstunna · 02:12:58 AM / 25-Dec-08

both are just as easy as the other. the problem(and its not a big one) with using the ka tranny is the drivshafts and tranny mounts. if you have fab skills then it is the better route. if you are in a hurry like i was then the bellhousing/tranny mashup is the easiest. but keep in mind im going ka tranny asap.

Nitro789 · 05:07:06 AM / 26-Dec-08

k got it thanx. Can i get custom drive shafts for it anywher or do i have to fab

s12god · 06:01:47 AM / 26-Dec-08

the KA will be so much better than the ca. Thats 60 x-tra ponies. Big difference. She'll have no problem kickin her ass sideways.

fyneyoungstunna · 01:20:54 PM / 26-Dec-08

go to a 4x4 shop, or look for a driveline shop. i dont know about where your at but here all the major car parts shops (driveline, tranny,performance,bearings,4x4) are all in one industrial area just outside of downtown.

SlickS12 · 02:21:41 PM / 26-Dec-08

Correct me if Im wrong Arro, but Im looking into this swap and I was told that you can make a franken-driveshaft using the front half from an s13 along with your original rear half. Direct bolt-on and no need for a custom driveshaft, well I guess that would be custom but there is no fab work involved in it.
