Default What size piping and WG/BOV

Going to make my own kit I decided. Just curious what size piping I need to run and what size WG and Bov. I decided that I am going to get a WG that release back into the exhaust. My setup is a 385ci LT1. Looking to run 20-24psi to make 1000rwhp. Its a GT47-88 turbo. If I cruise around town maybe on the weekends it will be set about 12psi. Is 2.5" piping to small? I was thinking that I should run a 3" dp or maybe 3.5"

I run the 44mm Progate WG from Turbosmart and it dumps back into my DP.. I run a 5" DP of the turbo stepped down to 4" before the K-Member.
1 3/4 primaries from the headers to a 2 1/2" collector and both feed the Turbo.
3" piping from the turbo to the IC and mt ATI Race Ready Bypass before the IC.
Then 4" out of the IC to the TB

Our setups are pretty close so I would guess that mine should be like this then..
