Compound turbo sizing advice

[3rdgenmike]

So, I have an 04 6.7 swapped, fire ringed head, BC rods, arp625s, flux 209%, dual 12mm cp3s. I'm putting together a compound kit and I'd like some help with my atmosphere turbo. The small turbo is an s369 sxe with a 80mm turbine and a 1.0 AR T4. I know I could go with better, but I already have this turbo. I'm looking at either getting an s488 with a 96mm turbine, and a 1.25 AR T4. Or an s488 with a 102 turbine, and a 1.58 AR T6. Or an s492 with a 103 turbine, and either a 1.32 AR or 1.58AR both T6.

I'm looking to get 1300-1400hp. Truck has a 2400-2600 stall and is a fmvb. Anyone got any advice?

I'd run the 88/96

As a plus, it's a "cheap" box unit to try first.

Mint, thank you.
