For anyone who might read this:

What are y'all doing for injectors and fuel pump? I want it to be set up for 1000rwhp. Not saying I will take it that far but I want room in case I do.

Originally I was going to do 80# high impedence injectors, 450 walbro fuel pump, and Aeromotive 13129 Fuel Pressure Regulator EFI Bypass 30-70 PSI Adjustable -6 AN, and of course the fuel rails I already bought.
I will be running e85

I did decide to go with Bosch 210s, fuel cell, and a Holley 12-1800 dominator
I think this will be plenty for me

Little update

Intercooler and speed daddy 50mm blow off valve came in. Intercooler I got off ebay as well. Should hold up well for my setup.
Engine is coming out of the car again in a few weeks to do forged internals.
