Ok i think i already know the answer to this but i just want to be sure. My 90 240s transmission is getting pretty warn out, i might be looking into replacing it some time next spring. if i do i would like to use the latest transmission i can find that will bolt up. So could i use a late model s14 transmission with my KA24e engine?? Thanks for any info

I could be very very wrong on this, but unfortunately I do NOT beleive that the trannies are the same for sohc and the dohc. If I remember right that is what I have heard before from others on this forum. Could be very wrong. Try doing a search on this forum for it.

Wrong. E and DE transmissions swap fine.

Thanks for correcting me rn240na. Sorry about the wrong info. I wasn't too sure if it was true or not, thats why I warned you about me maybe "well, now for sure" being wrong.

So, can you swap a s14 transmission into a s13?? or a ka24de transmission onto a ka24e? Someone said that the propeller shaft is too long or something. Has anyone done this and can give details as to what was involved in the transmission switch...

thanks...

Details? Unbolt old transmission, remove. Install new transmission. When you say 'someone said', who are you refering to? This is a good example of how misinformation gets out. Unless YOU know for a fact, YOU'VE seen it proven, or someone who is knowledgeable and has done it verifies it, it's hearsay. The driveshaft is fine in any application, why? because the transmission is the SAME.

Actually the "someone" is on this board and posted a thread about it...although I just looked and can't find it....but the post was referring to the fact that he had a built 96KA in an S13 and couldn't get the transmission on correctly...

The driveshaft problem is entirely unrelated to the transmission/bellhousing/engine combination. They are the same. (except the engine obviously)

The driveshaft length issue is due to the ABS sensor. The s14' with ABS have a slightly shorter driveshaft because the ABS sensor is on the third member (pinion housing). It adds about an inch of length to it, hence shortening the driveshaft.

OR.... it could also be due to the chassis length of the s13 vs. s14. The guy seems to have used the s14 driveshaft as well... or maybe it is the s14 diff he swapped... I can't tell what he's trying to say.

WAIT...

I just figured out his problem:

He swapped the s14 engine AND transmission... and his s13 driveshaft didn't line up (he didn't specify too long or too short). Point being, this had NOTHING to do with the engine and transmission not working together.

Summation... the driveshafts are obviously different lengths, the trannies are the same..... period.

Hey, I'm the one who had problems with swapping the S14 transmission into a S13 chassis. The transmission bolts up fine, but both the driveshaft from my S13 (noabs, 5spd) and the S14 driveshaft (noabs, 5spd) are too long to fit. I'm wondering now if the transmission that I got from the S14 is an ABS transmission, if that's my problem...

Did most all S14's have ABS? If I get an ABS/5spd driveshaft from an S14, do you think it would work?

What about if I want to swap in a VLSD in the future? Anyone know what VLSD's will fit my S13 and should I get a different driveshaft that will fit both the new S14 transmission and the VLSD?

No, I don't think most came with ABS... obviously a lot of them did though.

Yes, the ABS driveshaft is shorter for the reason I mentioned in a previous post. As for an s14 ABS driveshaft fitting your s13, I don't know.

I believe the s13 and s14 diffs are direct swaps, so you should be all set... I am NOT sure of this, so don't take it as gospel. One thing to keep in mind, the wheel base length and width are different on the two cars, so this may affect driveshaft length and output shaft lengths.... but I am not as familiar with s13 specs, so you should research this for sure.

what happened was this: They bolted up the S14 transmission to the car...both my S13 driveshaft and the S14 driveshaft were too long to fit without kinking. They measured my S13 transmission and compared it to the S14 transmission and the S14 transmission was slightly longer (0.5 - 1 inches).

So how does one tell if a transmission has that extra ABS portion? Is it visible?

Something isn't right with this scenario. Also, the ABS sensor isn't attached to the transmission.

No wait, back to my original statement, part numbers are the same.

Look at the first four replies! I didn't know if you needed to switch the bell housing, or if the transmission wouldn't fit at all, or if it will bolt right up to both engines. Between the first four or five replies I didn't know who was right, R240NA said "Wrong. E and DE transmissions swap fine." But, unless YOU know for a fact, YOU'VE seen it proven, or SOMEONE who is knowledgeable and has done it verifies it, it's hearsay.

Thanks....
