need fuel system info

[bowtiebuba]

im rebuilding my supra and am looking to get into the fuel system im looking to get 600 or 700 horse out of the turbo im runing now i was wondering what size injectors i should run. and should i get low or high impedence, also what is the diffrence between the two. are the stock fuel lines good enough to suport that? im looking to go dual walbros in the tank, with that be enough fuel pump for that power? I want to make more power some day so i want everything to be good to 1000 horse, im never gonna have that but i want to fuel system to be up to the task. im controling everything with aem too so i can keep the injectors workin

the calculations we always use for safety is .87 * cc = safe rwhp
you need low impedence injectors since our system uses a resistor box.
dual walbros will do the job, but ive always prefered a big single vs twin pumps.
the amount of fuel you will need to flow i would upgrade the rest of the fuel system as well. this would include a larger feed line, adj fuel pressure regulator, and bypassing the fpd. stock return would be ok, just bypass the J tube restriction.

what level would the stock feed line be to small
