How to have 1000whp whit a s50b32

[s50b32]

Hello all,

In need you help I well upgrade or change my setup for have 1000whp or a minimal 1000 engine hp.

Actual setup at 1.5bars (22psi) boost make 605hp and 732nm
Fuel: 2x 044
Rod: Arrow
Piston: CP in 8.75
Turbo: GT3582
Intake manifold: stock
Exhaust manifold: T3 bottom mount
Dump valve: Tial 44mm
Injector: Bosch 680cc
Fuel rail: PurePF AN8 in/out
Engine management: Powermod
Fuel: SP98

For a nice upgrade but not capable to 1000hp I have think:
Turbo: New PTE 6766 DBB anti-surge H-cover 4"in/3"out T4 divided in A/R 1.00 or 1.15
Exhaust manifold: VAC T4 bottom mount
Injector: ID2000
Intake manifold: for this part I need your help
Cams: VAC turbo agressive
Engine management: AEM
Fuel: E85
I tink whit this upgrade the car can make 800hp and 850nm at 2bars (35psi) boost

What you think from the upgrade and can you help me to find a intake manifold ok for 2 bars because the stock manifold can broken at this pressure.

If you have a full setup for 1000whp all suggestions are welcome

Massive thanks
