I was wanting to buy a LS2 fuel rail to compliment my LS2 intake for my project. I and shooting for 700 hp. Will the stock LS2 fuel rail get me enough fuel to my injectors or is it too restrictive for that much HP??
What do you guys recommend??
Here is my setup.. 4.8L, low lift cam, dual springs, LS2 intake, 92MM TB. Everything else stock...

Sorry about that, I can't believe I forgot to mention that I am goin to run a 76 or an 88mm turbo with 20lbs of boost! Goal is 700 rwhp..... Will that fuel rail handle all that or are some after market fuel rails gonna be required??

Also it will support like 1000 or more hp if you choose some good pump(s)

Better get some aftermarket AN8 fuel rails and build a good return fuel system with boost sourced fuel pressure regulator. In this case you will be 100% sure that if there is some issue(s) its not affiliated with fuel system.

Figure out your max power goals. If you want to just go overkill for 1000rwhp on E85, Id recommend the following:
FIC 160's hi imp
-10 feed, return, and two -8 vents
Fuel rails of choice with Oring boss fittings (not NPT)
Magnafuel regulator
Magnafuel 4303 pump
750rwhp on E85 is kind of the point where things get expensive. Im just over 700 on E with one external Bosch 044 pump, one 255 Walbro, 95 Delhi injectors on 58 base, Aeromotive 13101 reg, stock LS1 rails, -8 feed, -6 return.

How much more fuel do you burn running e85 vs running regular pump gas? I really do not want to run an external fuel pump due to overheating issues in stop and go traffic.
