S12 KA24DE swap driveshaft help - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey guys, I have an 86' 200sx se that I bought with a seized ca18et. I'm swapping a ka into it, and everything is pretty damn straight forward with the help of the write-ups over at s12club. But I've come into a little problem with the driveshaft.

Most people use the front half of the ka ds and the rear half of the ca's, virtually the same shafts. I bought what I was told is a 92' ka24de and manual tranny. It didn't come with a driveshaft as the guy i bought the engine from used it on his sr swap. So I drove down to San Antonio last weekend to pick up what I was told was a ka24de mt driveshaft.

After fighting with it for a good 10 minutes it wouldn't go in. I look at the splines and they are quite different. The driveshaft I picked up has two keys (two teeth missing) 180* from each other and the output shaft on the tranny doesn't have a key, it's complete splines all the way around the shaft. I tried searching everywhere but I couldn't seem to find any thing on the spline counts and layouts on the different driveshafts. I'll post up pictures this evening when I get home from work. I just don't want to keep sourcing driveshafts and them not be correct. Anyone have any clue what the spline design on the output shaft of a s13 ka24de mt tranny is? s14 mt? or the driveshafts? Is the SOHC tranny's output shaft different from the DOHC tranny's?
Thanks a lot everyone!

this is the inside of the ds I picked up in San Antonio. Looks exactly like my CA's old driveshaft. Could this be from a SOHC? ohh and it was perfectly clean when I was trying to install it. It got thrown in the dirt once i realized it was worthless lolz

I'll get pics of the tranny tonight, gotta get the car back on stands.

Got my answer over at s12club. Looks like that was an s14 driveshaft I drove all the way to SA for.... fail ahaha

The splines on S13/S14 MT transmissions are the same, you can use them vice versa
Only diff would be is if you have a AT DS

Still no clue but the situation is still as described above. Here's some more pics. Thanks for the help guys.

Has anyone seen that output shaft on a KA tranny before? It's definitely a 5spd and it's bolted to a s13 kade. PO said he used the driveshaft it was bolted to on his SR swap with no problems.
The driveshaft isn't in question really as now have 2 different s13 DS'. I picked up one like the second one in the above pic yesterday and am going to give it a stab tonight. TIA
