Is there any specific reason you aren't going with a single turbo setup? In some ways I could imagine (being you are running with a V6) its for simplicity but in other ways it could make it more complex (ie boost control etc). I figure you will need custom manifolds etc anyway.... with a single you only need one oil/water feed/return made up which could help quite a bit.
The other bonus is a single turbo is cheaper to buy and potentially easier to replace, and probably more support/understanding. For the power level you are going for a single GT30R or something of that sort would be insanely responsive, and if you got greedy you'd be able to turn the boost up and/or go a bigger turbo with minimal changes. Just throwing ideas out there...
