Question and a little Help needed for Fuel Setup

[JDMMA70]

Im currently trying to figure out what setup would work best on a car generating 480-590hp at the wheels. The car will be used for high speed runs (texas mile), circuit, as well as street use (daily), i read that walbros can only keep fueling the engine for a certain ammount of time. I dont want to go external if i dont have too. So im stuck between 550 and 680cc injectors, as far as fuel pumps go, should i run Dual Walbros, or is there another option out there for me?

Could use some help if you guys can.

Thanks
