You would need the trans from the S54 so it doesn't matter. The biggest risk would be the front diff and transfer case. Also, the adapter from the trans to the TC would have to be fabricated as I'm not sure it mates to the M3 trans.

It's been done on one car by some shop out east. It wasn't cheap and probably wasn't worth it. Adding a supercharger to a 330xi will get you nearly the same output of the S54 for much cheaper so I fail to see the point...
