need ur help
 

I have studied at a mechanical high school,and now i syudy fot mechanical engineering.
.I need a help from u .
i need to know from urs knowledge about my audi transmission.the problem are too much but the story is this:
i have an AUDI A8 D2 4200cc quattro.In this transmission the tronic gear change doesent work and the mechanical told me this s an electrical problem,this is the first.
The seccond is :
I need to make a "supercar" using my AUDI engine and all other systems on a tube chassis made by me.I need to know from u if i can use this transmission removing the torsen differential and using only the front weels output.the engine will be placed in the middle of the car.
please give me an answer im waiting for your help.

Mid engine rear wheel drive using front driveshaft output to drive rear wheels?

You can lock centre diff by welding it up or use a gearbox from front wheel drive car or transaxle from Porsche or similar.

ythank you i dont belive it is functioning with welding .bust be some thing more special.anyway thankyou

It'll work welded up. this is how you get your MK2 estort and Vauxhall Chavette to have LSD diff with out spending money on a LSD diff.

Thats' not LSD it's NSD( as in no slip diff )

sorry can u tell me wht is LSD dhe NSD?

ainarssems my transmission is not manual it is automatic tronic .if
i weld center differential can it work wif front wheels?

So you want to convert the car to mid engine with rear wheel drive.

Fit a gearbox from a front wheel drive car, I'd recommend the 2.5 V6 tdi gearbox as the ratios would be most suitable for the V8 engines torque.

Centre of gravity
 

I think it really depends on where you want your centre of gravity to balance the engine/gearbox and rear diff...

The engine/gearbox balance each other at the rear lift points...so if you have the engine slightly forward to balance the rear diff you could connect to te rear diff using the rear output shaft of the gearbox and ignore the front output shafts...

Automatic Transmission Tronic Quattro
If i block REAR OUTPUT i use FRONT OUTPUT of the TRANSMISSION
i WILL USE THIS TRANSMISSION FOR MY SUPER CAR BUT I DONT KNOW HOW USE IT REMOVING REAT OUTPUT.
CAN ANYONE TELL ME IN DETAILS? THNX
