thinking about fitting a turbo to my xr4 and i know the type 9 box wont take the power. but what power will a 2wd mt75 take? and what power for a 7" lsd diff?

 

mt75 is a 4x4 box mate 380 ish if used carefully
,2wd is a t5 pretty much bomb proof up 2 about 450 ish i think

 

was going to use 2.0 dohc box from 2wd sierra not a cossie box.

 

V6 XR4 or 4 pot ?

2 litre DOHC box does not have a long enough input shaft for the V6 and the bolt patern on the bellhousing is different.

If it's a V6 you will need to find a rare manual 2.9 granny box or get a hybrid made out of the front half of a V6 and the back of a DOHC.

its torque that will kill it mate 350lbs prob max

 

Anything more than 300 ft/lbs of torque through a 4x4 gearbox and lots of hard driving will see it go bang sooner rather than later
