Building a new manifold and adding a turbo for a car that's already a single turbo is almost trivial for a fab shop specializing in those things. Airflow is easy. Tuning is harder but bms seems to be saying they're ready when the kits appear and I doubt Vishnu would back down from the same challenge.
So all it takes is for the first guy to plunk down a bunch of cash and be without his car for 1 month to 1 year. Who wants to be first?
