Six speed transmission for the KA24DE

[jrc90240sx]

I am sure you could get a T56 from a cobra, vette, or ziper to work with the KA. I would just requier some custom bellhousing adapter. The only time I feel a 6 speed would be worth it is if you where making 400+ hp. even then just upgrading to a z32 NA rear dif would give you a final drive ratio that would give you a top speed over 165, and a lower freeway crusing RPM.

The more narrow your powerband is, the more gears you need to utilize it.

a t56 would be nice. they are def a proven trans. all usdm 240's have the same 4.08 rear as the z32 na. the final drive can be altered with tire sizing as well:thinker

i've heard some volvos have the same getrags as the supras. I do which we could adapt a sequential smg or smgII into our cars though. Imagine the new m5 7 spd?

[s13sr20chris]

heck i would love to have the m3 smgII but i have not heard of the 7 speed! thats cool!

So do you think if i got a T56 with some custom bellhousing i would be able to put it on my KA motor with no problem??? Do you by any chance know what the gears are on the T56?

[s13sr20chris]

hit up the google bro! i would also rec that you find someone to give you a price quote on that custom bellhousing before you buy the trans.

[nissan240sx92]

Why would i hit up goodle? Where should i start to find someone to make me a custom bellhousing?

[ca18datsun510]

um, search on google like he said.

i wouldnt be too worried about it.

if the mods list in his signature is complete, he is gonna be awful suprised when he hits the .50 6th gear and the car stops accelerating.

http://www.quaifeamerica.com believe the UK site has a gearbox with syncros for the silvia case..

linky no worky. one letter too many. nice pic though. look at how beefy that countershaft is.

[toptechracing]

fixed

[IvoryJ30t]

none of the transmissions listed has a final gear taller than .8

[toptechracing]

Why would you want anything taller than a .80?

[IvoryJ30t]

taller=numerically smaller

the guy who wants the 6 speed, wants it to increase his top end speed.

[toptechracing]

with a close ratio box you could run 3:70 or higher ratio.........

You'd be TOTALLY wasting your money on 6 gears. Do some research guy.

You'll notice on this page it says dog engagement. This means it has no syncros. If you look at the picture, you'll notice the dog fit loosely into the gears. This is to allow you not to have to use syncros. But shifting requires a very deliberate strong movement of the lever and it will be noisy as it engages. There was a NASPORT KA powered 240sx in an SCC article a while back that explained the noises they heard and the manner in which you had to shift with this type of engagement set-up. Not exactly what most people would consider comfortable.

As I stated when I posted the link. I believe the UK site offers a full syncro gear set. There would clearly be advantages to a six speed box over a 5 speed depending on your goals and desires. I think to say do some research is kinda short sighted cause I think that's what this person is doing. I have rebuilt 2 of the 6 speeds from a 350z and I can see the advantage of a low stop light 1st and a tight gear set 2nd to 5th with an OD 6th for cruzin...Different strokes....

OK so I checked the UK site and they no longer offer a syncro set.
