This is presuming you have the correct type of iff. The USDM turbo auto had the 3.76:1 ratio and correct 200mm ring gear. the LS shares this 200mm ring gear. The USDM turbo 6spd with the 3.26 ratio (differen from the LS400s 3.26:1 ratio) had a 220mm ring gear, which makes the entire rear diff and axle arrangement incompatible.
Confirm you have a 200mm ring gear and you're good to go.
After being fairly certain I had the 200mm ring gear, since it came of an auto supra, I stumbled upon this page: http://www.supraforums.com/forum/sho...ferential-Info
! and was certain no more..
I had been reading too much on US forums. As it turns out all Supras sold in Europe are 220mm.
Now Sweden is flooded with JDM imports but from what I can google mine is a big diff, like the one on the left in this picture:
Does anyone know if the whole pumkin would fit, like this guy is saying: http://www.clublexus.com/forums/6019988-post18.html
and if so wich axle shafts I could use?
Or is it better to return it and buy a new kaaz and try to find a Supra small diff rear cover?
