Turbo selection

[808Supra]

Hey guys, after some major ovehualing, like new forged internals and a aem ecu and all that good stuff i would like to put a much larger turbo on my 7mgte, but i cannot decide which one, First i was gunna go for the to4b but i dont think this will cut it and id rather not modifie the car twice? im looking to get about 720 whp on 92 gas? but i need a turbo that can handle a wet or directport shot of nos, (just incase) the nos is for back up, and mainly just for show, im not a huge fan of it. Not against it, just not crazzy about it. Anyway, i thought about the T72 fron turbonetics (duh) but i dont think it wiill mount without some custome headers and what have you, so id rather just buy a turbo that had equipment already made for it to suport a 7mgte application that can run 700whp plus an ocashional nos shot to take it up to 800-1000whp without some crazzy minimum booste requirements.... any ideas?
