Hi, Guest
Both the Torsen T2 and the Quafe are the same internal design. I have yet to see a torsen break, think about it do you need to spend double on a Quaife to get the lifetime warranty, when something else on our car will die before that.
For both of these diffs output is 50/50 between both wheels when your driving stragith. The Quaife has a 2-1 biasing ratio, this will take 66% of the power away from the wheel that spins and send it to the wheel that has grip. The torsen has 3-1 biasing ratio, that will take 75% of the power away from the wheel that is spinning and send it to the wheel with grip.
On a turn the power is sent to the outside wheel rather than how it is now the inside wheel lights up. (well on a hard fast turn).
The torsen is said to only have an HP rating of 500hp, the quaife claims around 800hp.
There is another thats mostly used for offroad/ralley, the KAAZ differential I don't have much details on this other than it is a clutch type differential, needs a good amount of break in with special fluid and requires user calibration for the wheel lockup characteristics required.
For your gears, only 4.06 gears are available from ford racing. I think that for someone that is Normally Aspirated or someone with a near stock torque curve it would be beneficial. I think that being turbo these gears may hinder the output to the wheels. ie: at the track you will light them up ALLOT quicker!
While your doing tranny work maybe think about a new clutch, and possibly a lightened flywheel.
