I think it might be more along the lines of not having the technical know-how rather than lacking the desire. The N54 is more of a 'traditional' turbo six in that it uses two tiny turbos much like the B5 S4. To go faster, simply upsize the turbos slightly and trade some lag for much more flow. With this dual scroll thing it is infinitely more complicated. I don't even know of any other production 6 cylinder with a single dual scroll turbo as a point of reference. I know the outgoing 911 Turbo used a couple of adjustable vane turbos. Anybody know of one?
I think the reason why nobody wants to make an upgraded turbo for the N55 is because there probably won't be too may people in the market. How many can they possibly sell? 10, 20, 30 kits? There are no more of our cars being made so the # of people that want it is limited. But making it for the F30 will be a smart idea because like the N54 it probably won't change for a good 4 years. Thus always bringing new people in the market.
