Wow, nobody knows anything about the strength of these things, I guess thats a good thing.

Does anyone know where to get a set of synchros for this trans?

 

Don't quote me on this as I do not know for certain but I do believe it is around 500wtq that the transmissions like to grenade.

However, and don't take this the wrong way .. but I don't think you'll get to point of the tranny breaking. I see so many posts of people claiming grandeur with their cars and they don't really realize what it takes to have a 600hp car, nor what it actually feels like. I mean especially in a RWD car, that is a fuck ton of power.

 

30 #'s on a completely built meth injected motor will get me where I need to go. Don't worry about me not making as much power as I think I will, worry about my trans.

 

i dont remember how much the 240sx tranny can hold either but you always have the option of switching to a Z32 transmission which can hold alot more power.

 

any writeups on the Z32 trans?

 

they sell a conversion kit for the z32 tranny, its like 900 bucks...

ive n ever heard anyone break a ka tranny honestly, even if you did break one, you can buy another one for relitivly cheap...

as for trans rebuild kit/ syncros, no clue...

o and are you running a open rear?? and want 500wtq? well that should just get changed out either way...

what motor you using? what will you be using the car for?drift,street,drag?

Im not sure what im gonna do about the rear end yet, my buddy has a 300zx n/a rear end that I may swap in there but I have to do a lot of reading before I make any decisions.

Im using a ka, if I stay with this rear end I will end up buying a 2-way kaaz but that crap is so expensive that im not even going to think about it right now. That car will be used for street and strip, also some auto-x once I have the money to buy some adjustable coilover.

The car will be capable of 500wtq, (well the motor atleast) but I doubt I will want that much power all the time since I will drive it on a almost daily basis.

 

link for the kit? I searched google but couldn't find it.

oh and last year i remember seeing one of the mazworx guys running about 800hp on a z32 transmission

 

You're planning to build this car for over 500whp and yet the Kaaz 2-way is too expensive for you? :hhahaha

 

dude dont knock the guy because he isnt rich. Some of us have families and other things to take care of. But from what i hear, even if you get the z32 rear, yor gona have problems with the half axles. I believe the j30 rear is stronger then the z32. oh and ka trannies from what i understand are good for 400+, my friend has one and he is always changing the tranny, he makes about 450 but he drifts so he is grabbing gears hard.

 

That's not me "knocking" him because he's not rich, that's me bringing him to reality. You think I have the money to drop on a Kaaz 2-way? Hell no. My schooling is far more imporatnt to me than a piece of shit car.

My point is, it's NOT cheap to build a car for that power. At the point of dropping enough money to build a 500+rwhp vehicle, the least of my worries would be the cost of the Kaaz 2-way LSD. In comparison to everything else, that would be dirt cheap.

 

Dark-Hawk pretty much said what I was going to. 600hp and a kaaz is too expensive? Keep dreaming kid, your not getting anywhere near 600hp. A decent reliable fuel system for 600hp is more expensive then just a KAAZ lsd for fucks sake. Don't cut corners, save your money.

Also, NA Z32 and J30 LSDs are the same as stock 240sx diffs, R200s. I have never heard of output shafts breaking, just axles.

 

ok, well guess i was wrong, thanks for the correction, i heard somewhere the the j30 had better half shalfs then the other ones, but who knows.

 

Thank you pa s13, you're right, these peeps don't know my situation. Not that I need to provide an explanation, but since you're ignorant, I will.

Im a student and before I went off to school I had a kick ass 14$ an hour job, that is when I bought all of my parts for my motor and 5 spd. swap. Right now, I still need a few parts (clutch, fuel upgrade, flywheel) and I get a little over a grand every 3 months to spend on books, so, I buy books, then I invest some, and I save the rest and spend it on car parts.

So, a $1100 lsd, which isn't neccesary to drive the car, won't be purchased right now, maybe in the future.

Also, the entire fuel upgrade minus the 255lph pump is about $600 on AMS, and that IS necessary to drive the car. And, since I would really like a car to get around town, getting it moving is a priority to performance mods that can be done later. I know I will be buying rear axles from AMS as well, but, im not going to be launching on DR's for a while so there's no point.

p.s. I never said I was going to be getting 600hp, I said 500ft-lbs, I don't give a shit about hp.

 

I'd like to live in the world that you do where a $14/h job is well paying and means I can dump senseless money on my car without worry of repercussions.

To achieve 500ftlbs of torque your car will need to have over 600whp, thus why we're bringing up the amount of horsepower here.

At those power levels, an LSD is necessary to be able to actually transfer said power, to the ground else you're just going to be sitting there with one wheel breaking loose.

Ignorant? No. Just someone that's not naïve.

240SXAddict brings up a good point too, whilst one tranny will be capable of holding xxx amount of power, another will explode with half that power going through it and so on and so forth.

 

try and find a ka24de trans with low milage.If you also dont have money for a lsd setup bust out the mig or stick welder and weld the diff in the rear.Believe it or not there is some ka24det's that are making serious power and still use a ka24de tranny.I personally know people that abuse the ka tranny on the 1/4 mile and its still in one piece so put 2 and 2 together

 

I like how everyone thinks there are magic numbers at which point the transmission breaks.

A friend of mine ripped his ka24 transmission to pieces with a ~250whp RB20...

and Brian wilkerson grenaded a z32 tranny with his 500hp monster...

 

Yeah, you might be better off with a nice gear set or something.

Also, I make $14/h right now and I have zero dollars saved. I'm waiting for my profit share in december, then its on.

 

Well since I was 17 when I was making 14$/ hr and I had nothing else really to spend money on, most of it went to car parts, and through about 6 months that meant my engine was built. I don't know if you don't believe me or what but, I just posted a project thread that has dates on all the pictures so....

I know different tranny's go out at different times, hence why I said, if the tranny is in good condition should it hold that much power. I ripped it apart the other day and everything looks to be in decent condition except the reverse gear has a bit of wear, I have yet to take the synchros of the shafts to see what they look like inside.

What im trying to say is, if the tranny is in good condition the odds of it holding its maximum capacity of power is better then if I just threw a random trans that may have been wore to all hell.

Also, I have seen ka-t's make way more torque then power, at about the 320hp mark the torque was at 350ft-lbs, granted im sure the torque curve levels out eventually while the hp keeps rising but still, I doubt there will be a 100 difference between the two.

p.s. I didn't mean you were ignorant as in stupid, I just meant ignorant to my situation.

 

Yeah, you should post those details with the thread! I saw the other thread and it looks good. You should consider welding your differential, thats a cheap solution. I read on another forum ka trannies start taking craps at around 350ft-lb/s or so. Also, tire size and how you drive the car will change how long it lasts as well. I met a guy last year with a built KA and he pretty much said if you don't beat the shit out of it constantly, don't shift hard, etc and you should be okay.

I always had alot of expenses and I still do, thats why my cars are still slow. I can't wait till december.

 

Is there anyway to make your own kit (you know, something that is dueable to make) for a z32 transmition swap

 

most people ive heard still running the ka trans have the syncros micronited and a full rebuild and beat the hell out of them. but for 500tq i would recommend saving the money and goin z32
