Is it worth spending £4000 plus? Depends what your trying to achieve, a few more details would help
Cheers

I here that Zcars are toying with the idea of supplying Busa minis with a diff set up would you not a agree that as stated it would be less noisy, maintenance free, mechanical reverse and quieter than the chain. I know the installation from the original setup will have to have some major changes such as swing arms, shafts etc but I want to check it out to see if it is feasible.

when i had the mini, there was endless problems with the rear end setup, constantly swapping parts, renewing parts etc. to be fair by the time i sold the car all the problems had been ironed out. i think that a pukker drive box would be much better and may also mean that the centreline of the diff would be lower to the ground meaning that the drive shafts would be running as level as possible. the v-tec setup is a better setup as the driveshafts sit level with the ground. after owning the mini, i would consider building a mini from scratch, however i would not use trailing arm setup, there are better ways of a suspension setup in my opinion.

How are things thanks for the input I also know it would be a great improvement to the car carrying out this procedure but from your experience how should I start this, you mention omitting the trailing arms is there a way of custom fitting a drive diff from another setup?

The idea of a proper diff sounds excellent to me, it's just the cost that frightens me!
Why would you need to change the swing arms? These boxes like the quaife powertec qba3r aren't very big, there would no physical reason you would need to change swings arms, but like ed says there maybe other reasons why you would want to change.
I considered turning the engine 90 degrees and driving a very short prop shaft to a conventional diff, ie Sierra/Freelander, but when I did the measurements there just isn't enough room and the driveshaft angles are hideous

the powertec diff would be my road if i were building another mini.
the trailing arms would probably work with the powertec setup i would just rather re design the full rear end..

Hi these are the best photos I can find to show you the layout of the engine in relation to the frame

In my opinion chain breakage and gearbox damage is due to the fact that there is nothing in the z-car setup to absorb the shock.
On a motorbike there is a cush drive in the rear wheel to absorb shock.
