is there a kit that changes the KA tranny's internals for stronger gears and such?? Also how much can the KA24DE tranny handle hp and tq? Thanks

drnovascotia

it can handle upper 200 hp range, it's a tough little tranny. Dunno about a build for stronger internals, most people don't have to worry about 300rwhp on their KA.

does anyone know how much stronger is a tranny that has been cryo something treated?

Zdrifter

here's an idea; if you need extra strength go rip the trans out of an '83 280zx turbo. That is a borg-warner T5, same design as in 5.0 mustangs, 83-92 Z28's, and a bunch of 300zx's from 84-89. It's plenty strong to handle the KA, and it's easily rebuildable. Remember though, ONLY the 280zx turbo trans will bolt up.

can it handle a 350whp RB20DET max? thanks

for some strange reason, i'm thinking that if u get an RB20DET, u'll get its transmission, too (which is quite strong)...

93RPS13

there are rumors that RB20DET trans go after 300whp, and i heard that the RB20DET tranny is basically the same internally with the KA , that why i asked the question

Zdrifter

close to same internals, not the same bellhousing.

93RPS13

yes what you just said i forgot to add that thanks

Sil40_Mayhem

oh, okay then.

well from my understanding the sr20det tranny is good for up to around 400hp so i would imagine that the rb20 has got to be atleast that good...right?

Dounveeme

and on a side note, if the rb20 tranny could ony handle 300hp why in the world would a ka tranny be any better? its in a lower class car then the skyline with a less powerfull engine...
marinate on that one for a bit lol

93RPS13

i dont know about a SR's but have you been reading cuz a KA and RB20 trannies have the SAME INTERNALS that why i asked the question about stronger gears etc...

element

an 83' 280zx borg warner t5 will fit in a 240sx?
how about s14's w/ sr20det?

DriftS14

ya know for some reason i never even gave it a thought..
But how about those guys with 400+ HP KATs? Would you actually need to modify the tranny to handle that kinda power???
