Eh... a built 4V with a procharger is going to need a pretty serious fuel system. The sentence "I don't want to pay" in the OP's post is not something that should really come into play when you are talking about this sort of setup and power level.
Twin supercar pumps, a BAP etc... I'd even go so far as to say do a triple pump setup so if one fails the other two still can feed enough fuel to the system. Surge tanks are always a good idea too if you are putting out a lot of power.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
