Don't know just a thought.
Take one look at a TT Supra and you'll know why. The plumbing involved is a nightmare. And it doesn't use a fully switching system. It spools one turbo initially, then it opens up a valve to spin the second turbo along with the first so it becomes a twin turbo set-up. Running a parallel system would be easier, but highly unnecessary. I'd say cost aside, space is the biggest issue of running a sequential set-up. Even in the Supra, space was so tight, the manifold was made to be really small and restrictive. Quite frankly, the Supra could have probably had the same spool up from bigger turbos if they would have been able to use a better manifold design.
