Half bridge

There is nothing wrong with pp turbo setups. You should make max power around 8250rpm . Carbons are out . Steels will be fine . Na rotors bad idea use turbo ones. Better to drive with side port combination. Go to big on turbine ar. sweet spot will be too high in rev range. T51R kai or spl would be good. 4 x 850 + 2 x 800 enough injector for 680 - 720 bhp .

so this engine will not need to rev high for power then? and 2 t04s sound a little big to me unless they are both in the .5 AR range. and you mention Pports not liking backpressure, well to get a turbo to move you need back pressure

.... sooo there needs to be some kinda compromise. and i think 2 smaller turbos does sound like a good idea. possibly internaly wastegated ones off of a stock evo. that should flow enough.

this engine will have to scream its nuts of to make power, especially using a large exhuast housing or two if you go down the two turbo path... the idea of using two stock evo turbos scares me alot.. you should really think about using a custom ecentric shaft , getting the housings/plates oversize stud kitted, external oiling system for reliablity as all the PP turbos i have seen use external oiling systems.. and there all run on methanol, PTS seals or IANETTI ceramics seals would be the go, have you researched any intake setups? guess theres a few different options?

The powerband of a peripheral port turbo isnt where you think it is, the power peak is not that much off side ports when turbocharged...On a 2 rotor, all of the stock parts would be usable if you started with an FD core as the basis.

hummmm now to find a FD core with toasted housings....

i would much rather go with one large single for simplicity

i was sorta thinking to run 2*1680s and 2*750s that should be enough fuel

and as far as intake setups goes. i will just make my own, i was hoping to just toss one together out of steel first to find where the engine needs help at most on the dyno then redesign and make a final one out of aluminum.
