This occured to me whilst I was fallin asleep the other night (sad i know!) whas anyone ever tried using 2 differing size turbos with a custom manifold

e.g. use 4 cylinders to drive a large turbo and 2 to drive a smaller turbo, assuming you could use 2 boost controllers to controll each turbos wastgates so that the small one only boosts to say a bar and the larger turbo can boost to 2bar say. It would seem you would get the best of both worlds with virtually no turbo lag..

Would this be possible?
