Bigger Fuel System?

May sound like a dumb question but will a upgraded fuel system (preparing for turbo) give you a little more HP (before the turbo or any other major mods) fuel system upgrade as in fuel rail, 450cc injectors and a 255 lph fuel pump?

thanks

No, not really usless your current setup is starving for fuel. I will tell you right now that without some kind of engine management, your car is going to run really fat till you turbo it. The stock ECU will have a hard time idling those 440cc injectors. I would wait and do it all at once with the turbo unless you like having a car that puffs black smoke.
