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?

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?

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...

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?

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

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

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.

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

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.

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

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.

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.

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.

Yes that's correct, this is how mine is set up.

I strongly recommend the KA tranny, the shifter shifts solid, and the shifter is about 5 inches closer, which is LOTS better.

not quite 5", but with a short throw shifter, quite a bit less throw.

so if my car was made 6/86 it's a c trans wright?

mk1.5... so most likely.. check your plate in you engine bay.
