how much power will this fuel system be good for??

I just put in a new engine and iam about to order the PFC and I also want to upgrade my fuel system. My question is how much power will 4 850cc injectors (iam replacing primaries) and a walbro 255 be good for? also would I need a fuel pressure regulator?

You wont need another FPR the stock one will work... the injectors should hold up around 350 or so... if you have more mods do more and whatnot... replace your filter while your at it. check your FPD also... its on the end of the primary rail... for leaks.
Take it easy,
