["Puddles the Pontiac"]

i plan to build a twin turbo engine this febuary. my only question is the fuel system. i know i need boost reference regulators and more fuel over all. but do i need a high dollar pump or can i get what i need from two smaller pumps? the aeromotive peice i am looking at is not too cheap, but i have one holley blue. and getting another would be much cheaper. any other fuel system need brought up would be appreciated as wel. thanks to all.
