Gearbox for 400ft/lb??
SimonNOS - 30/1/04 at 07:05 PM

I'd like some recomendations on what gearbox to use in an MK Indy with a possible 400ft/lb of torque?

I'm gonna me making a custom bell housing so it doesn't really matter what make so long as it'll fit in.

Cheers, Simon

Borg-Warner T5 from cossie? Seems the logical choice.

there is a gearbox made by / or called tremec


do a google

when peeps do a manual xjs conversion (over 300lbs iirc) they use either a T5, a supra box, or a tremec

think the tremec is best - think it costs over a grand tho...

Tremec seems to be the choice for modern big V8 american cars certainly.
Supra box is v strong too as mentioned.
Maybe RWD Skyline too? I heard of Cosworth people changing to skyline running gear because the MT75 can't take it.
Real Steel will sell you a Tremec box I think, give em a call.
May I ask what engine you are putting in?

i have heard if you use the supra box, one or two bearings have to be uprated.....

on major tuned supras they tend to use the auto box, apparently its stronger than the manual one. Only hearsay though and fairly irrelevant to us...

Hi

The Luego that used to be on the home page of this site ran a "Getrag" box.
( Was it a Jag engine? )

It's what I'v got hooked up to my Lotus.
Cost me £150 (result)

mackie - the cossy boys are changing from MT75 4x4 to the skyling 4x4 not only because of the limitations of the mt75 box, but the skyline box (or some of them) have selectable 4x4 more fun
