Or any hybrid.
In regards to the comments about this solving turbo lag...anyone ever hear of a sequential turbo setup? Either via two same sizes turbos (in the case of the RX-7) or a slightly larger secondary (I can't think of an example at the moment).
Granted this is less complicated mechanically and far more compact, turbo lag, when implemented correctly is not noticeable, if present at all. the downside of course is cost.
