I've not really seen any V6 engines using Twin Scroll setups given their cylinder firing order. Is it really worth using a Twin Scroll Turbo rather then a traditional one for our application? Or was the Turbo selection not made with it's Twin Scroll function in mind?

I was also going to mention that the BMW went from a twin turbo N54 to a twin scroll N55, although some say the N54 made more power.
Also, the advantage of a twin scroll has to do with the order of firing pulses. Because the Z uses 1-6 firing order on alternate banks and Sasha made sure to keep each header equal length, the pulses will enter the split turbine housing alternately which adds to the efficiency.
I'm sure Sasha can chime in here with more info.
