Why don't you just get a 35d engine from an e9x? They're all twin turbo M57.

Get the stock HP/LP turbo setup from a 35D and install. This will be your best bet.

M57 isn't exactly a twin turbo. Yes it has an HP and LP turbo but they don't run in parallel like in a N54 gasoline. The HP runs until a certain RPM, there is a transition RPM where the LP comes in and then a bit later RPM, the HP turns off. I would call the M57 a bi-turbo and it isn't compound either.
