My goal is 700whp on built gsr. But im planning on doing a walbro intank and bosch 044 inline going to aem fuel rail and aem regulator(or another brand regulator). The lines are stock right now but I will up grade if needed. The injectors are rc 1000cc peak & hold. Will this support my goal or would I need bigger injectors or what? Thanks in advance.

 

Don't know if the RC 1000's will get you there, you'll be limited on FP capability with them. The Injector Dynamics 1000's will do it easily though, they can run up to 100psi base pressure, which your setup will easily do with that pump configuration.
