Okay guys. I am in the process of buying my upgraded fuel system, but I wanted to make sure that the stuff that I am buying will be enough to properly support my setup. I am running twin 2530's and am shooting for about 575-600WHP.

Should 720CC injectors be enough to support 575-600WHP? Or do I need to go with bigger injectors? Thanks guys.

720's will be heaps big enough. Not sure that the 2530's will make 600hp at the wheels without chopping the air a lot. would need a lot of boost, as that would mean that you make about 700hp at the engine. That said there IS a full bodied drag R32 that makes 440+kw (about 590hp) at the wheels (don't think it is on street fuel though) in Australia.

hi mate wont make that on 25/30, mine ran 520 @ the hubs max 612bhp @ the fly would need 25/40 or the gt rs but you then suffer lag issues..also has bean has said for 700 @ the fly 720,s would be getting very near there max possible running 85-90% which is ok but not recommended.bernie

I will run my GT2860-5 (same thing as 2530s) with Denso 700cc and an Apexi fuel pump. I'm pretty confident that that should be enough to supply enough fuel for the turbos. But you're right in thinking that you don't want the fuel system to be the limiting factor in your engine build - I keep wondering if I should run a parallel Apexi pump and toss the stock fuel rail for a dual feed Tomei rail.
