So here's what I'm working with. 2002 24 valve, converting to built 215 P-pump and upgrading the turbos. The truck is currently running BD R700 twins (58 over 471). The owner of the truck is gunning for 1100 HP. It's just a toy, may see some street time but mainly just for playing. He wants to utilize the turbo plumbing he has and replace the turbos. The secondary turbo is no problem, thinking probably a 64/80 or 66/80. The problem I'm running into is the primary has a T4 flange, which limits my options. I did some research and found the S482/87/1.25 T4 turbo.
My question is, will this turbine support anywhere near the 1100 number on a p-pump 24 valve, or is the 96 mm turbine the way to go? I realize the 96 is probably better, but considering the T4 flange, it's not the easy option.
My recommendation was ditching the current setup and buying another complete kit, but he is trying to save money. I know 1100 HP isn't a "budget" build, but he wants what he wants.

P.S.- I see some shops offering custom 96 mm housings with a T4 inlet, this may also be an option.
