k box and a T series diff yo

[KKUSTOM]

hey guys,

does anyone know if a K gearbox and a T series diff combo will work without a custom tailshaft?

i am asking this because i have got a destroyed borgy diff in my 4k ke70
and don't what to spend more cash on it (noshit)

i am planing to go 4age next year anyway so should I wait and do it all at once.

any constructive advice and help is appreciated

thx man Josh:thumbup:

nah it doesn't dude.

i tried it in my old ke, and only realised after i had changed everything over except the tailshaft >@ >@ >@

I havn't checked all the lengths to be certain, but I think a early TE72 (T-18 SE) driveshaft would fit. I know the splines are right for the gearbox.

Custom tailshaft or bust man.

I find this very interesting, gearbox length and mounting position relative to the diff will be the deciding factor if so.

The T40/T50 and K40/K50 gearboxs had the same output shaft splines, up untill the middle of the TE72 run. Late TE72 and all AE86 have a larger spline.

The T50 is also the same length as a K40 gearbox (from a KE30).

As far as i'm aware, the splines went as such:

TA2x Celica and S1 TE72 had the same spline (or S2, can't remember)
AE7x, AE86 and TE72 (whichever one i didn't say earlier) had the same spline

Also the extension housings changed on the K box on the KE70, they are longer.

t18 diff (at least series 1 ie no swaybar) definately fits ke70 4k k50 box with t18 tailshaft - i used that combo before changing 4age then changed the front half of tailshaft to an ae86 front half.

Interesting.

thanks for the advice guys.

what do they use instead of a swaybar?

[Fusion]

They had no swaybar, just how it is. You can buy weld on swaybar brackets from AJPS though

I don't run one in my AE71 Corolla with a T18 S1 diff. If you want to I could take you out for a quick spin to see how it feels for you after I get my front end sorted this weekend

[KKUSTOM]

wow how has Toyota stoped the diff from moving then?

[Hen may possibly be a nut]

Swaybar != panhard rod.

One stops roll, the other stops the diff exiting the side of the car.

With no swaybar the rear just feels a bit floatier than if it were more rigidly attached. Its better for grip with no swaybar at all, or an adjustable one wound back pretty slack.:))

thanks for all the help.
