WEPN R

Hi just wondering if anybody out there know how much horsepower a fuel pump from a 2.2 Vtec will support and also how many lph if flows.
I want to turbocharge a B16a2 running 6-7psi and want to know if they would be a good upgrade to cope with the fuel requirements, also running 2 extra injectors and standard fuel pressure regulator.
ps. would it be good to use a rising rate of normal adjustable fpr if I decided to upgrade the factory regulator and why?

thanks
