I'm looking for a turbo that gives upper RPM performance, and researching how the low end power can be achieved. I've never heard of a twin turbo B-series motor to handle low and high RPM's. That would certainly be pretty cool, but I'm not sure if a B18C1 would move enough volume to run two turbos. Maybe a low spooling supercharger and a high spooling turbo to take over at high RPM's???

I've got this dustcloud of theories and ideas in my head; I'm trying to clear 'em all up.
