6-speed CA18DET?

[TD or Not TD]

I thought i heard before you can run a CA bellhousing, seperate the case and use the housing of a CA on a KA or SR transmission. could this be possible for the S15 6-speed transmission or is it completely different? sorry i do not know enough about it to be sure.

[ca18detgabby]

Im about 95% sure you can as you can with the KA and you can use a KA trans with a CA bellhousing..........

I do have to ask? why would you? mazworx sells conversion kits for a Z32 6speed to work with the SR, and Q45...... it would be much if anything to make one for the CA and they are pretty cheap for the amount of work.

[themadscientist]

the six speed is weak. I mean physically not cool guy speak.

[MeanGreenS13]

yeah, what he said... the 6speeds SUCK! i had one for a few weeks and trashed it first time through the gears at the track... guess it didnt like the bottle =)

[TD or Not TD]

Well i can get one for dirt cheap locally so i wasnt sure, plus i have an extra CA transmission.

also is the S13-14-15 driveshafts the same. because i dont want to have to buy 2 driveshafts for the corolla.

Arent the S15 engines 250+hp? and the transmission holds up to that... i would think it would hold up to the CA just fine. i would have to take some measurements as well to find out shifter location ect.

[themadscientist]

gears are thinner, they break behind hopped up SRs. less than 350 or so they should be fine. Snap it up and try. Worst case it won't work and you sell it for a profit.

[TD or Not TD]

lol yeah but meangreen, i dont plan on running anything more than 200-225whp for a while. so i think ill be safe. no spray going through this car lol.

also madscientist, do you know for sure if it is "as simple as" takeing the housings off and swapping it out?

input shaft the same spline count?

if so i might be really itching for that 6-speed and trying it out. my speedo doesnt work anyways and the harness is not hooked up to the transmission lol. (cable driven in the AE86) plus looking at different pictures online it looks like it sits the shifter more forward possibly a few inches where it is supposed to be in the car. i might go check it out if i get a day off this week and make sure they still got it.

[themadscientist]

I am not sure about the six speed. I have an RB transmission that is like the KA. SR and CA and it spent some time with an l bellhousing on it. The six speed may have a different layout and not accept the CA bellhousing. I will likely be using a five speed SR transmission with a CA bellhousing so I can slam some PPG straight-cut gears with dogs in it.

[MeanGreenS13]

cable driven speedo? you may want to look into the RB20 trans and see if the bellhousings will swap. That was a cabledriven speedo trans. I had one =)

[themadscientist]

they switch out. The drive for the cable and the sensor are the same.

[MeanGreenS13]

couldnt remember how they connected with a cable style...

[themadscientist]

The business end that sticks into the transmission is the same, the actual gear and the housing bolts down to the transmission case the same. So you can yank a driven sensor out and slide a cable drive in and vice versa. There different ratio gears I think though. I know my R30 was originally auto and with the 5-speed in it the speedo is really off. Not sure how to determine which gear to use.

Eeew . Don't get yourself in trouble for a little bit of authenticity/rarety. It ain't worth the headache..................

it was just an idea, if i can get the 6-speed for cheap i might not mind it. but out of the 3 transmissions(Ca Sr Ka) which one is the strongest? the SR? either way id like to take a look at that 6-speed to see. maybe if i had some specs on it to figure out the spline on the input shaft ect.

[r34 gtr]

Yeah man, give it a shot. Worst case scenario you sell it to some noob with an SR and make some dough.

[TD or Not TD]

how simple is it to swap out bellhousings from CA to KA to SR ect.? should be fairly straight forward right?

[themadscientist]

pop the throwout bearing guide housing off. Inside the bellhousing, the part the TOB slides on, has like si bolts holding it on.There is a snap ring around the mainshaft bearing, take it off.Take out the bolts holding the front and rear housings tother, it will be a real PITA.Slap the new bellhousing on and put it back together.For old trannies like FJs and Ls the countershaft bearing is smaller than the SR, RB and CA and I assume the KA as well so you would need to put the smaller bearing on the newer gearset to use an older bellhousing. Now, I have never cracked open a 6-speed SR so you will have to see what's going on with that yourself. Let us know what you discover.

I've read that nitrous oxide at low rpms is one the worst things for a transmission wear. I guess because it's pushing so hard on something that is not moving very fast... I dunno. Some people use a computer to only allow nitrous oxide to work at certain rpm's in certain gears to help the drive line or help with traction.

Out of curiosity have you broken any other transmissions? from your experience the 5 speed is definitely stronger. good to know.

I've heard that the S15 6 speed has the speedo drive in the diff. I've looked in the S15 service manual, and it's in the FI section of the manual. (Which I don't have)

[biosehnsucht]

I'm pretty sure the S15 6 speed cannot swap bellhousing with KA or other SR transmissions (different bellhousing to transmission bolt pattern) and therefore would not be usable on a CA.

[ca18datsun510]

z32 trans is a 5 spd, not 6 spd.

the s15 sr 6spd is a different design, its a 3 piece setup, it will not work with ka/ca/rb20 or older s13/14 sr bellhousing.

it has no speed sensor, as the speed sensor on s15's is in the diff.

the drive shaft is not the same. the output of the trans is different, as well as the length.

saound interesting, I also agree that it would be usable on a CA

[Chinamandrift]

i have a CA bellhousing mated with RB20 transmission ........the shifter sits further forward compared to the SR and KA transmission .......in my ae86 the rb20 shifter location is still a good 5 +/- 2 inches away form the stock position .......i was told from someone who had experience ...that a CA20e.....or CA18ET transmission will sit even more further forward and is almost in the stock position in the ae86 .....but that guy had an sr in his ae86

as for the 6 speed ....i have no experience on it .......my 2 cents id give the ca20e/ca18et transmission a try ......because i wasnt very comfortable with the shifter location .........doesnt feel like my corolla anymore ..plus we have those trannies in the junk yard ive seen em everywhere ......how does your car feel with the shifter being that much further away from the steering wheel ??? .....i dont see any low price 6 speed trannies tho ........although it would be nice to figure out the shifter location on the 6 speed transmission

we might be the only ones in the US trying to perfect the cae186det build ...anyone else out there ???

did you post in the right thread?

if so, what the hell are you talking about?
