brfatal,
Isn't this more true of the parallel turbo design than the sequential design? The Maserati bi-turbo and the RUF 'Yellow Bird' had a parallel turbo design.

Agree that both turbos will be working in either design and twin turbo setups are not cost-efficient.

from what i have heard from this guy the engine exhaust runs to the little turbo then to big then out.

I think like he said above you're talking about a parallel system which i heard wasn't that good. haha im trying to justify spending the money...... but i dont wanna do something stupid. haha..!Laugh!

It won't be the initial cost that is the problem. The problem lies in being a guinea pig for a new setup and having R&D issues.
