Depends on how much hp you want???
From what I understand around 700hp+ (at motor), probably would be looking at a dual external fuel pump, duel fuel filter setup, duel FPR, etc. That means fuel rail wise, one fuel pump feeds the front, one fuel pump feeds the rear of aftermarket fuel rail with a single exit for fuel in the middle of fuel rail.
I think Sard make these dual entry fuel rails -
Also might look at a surge tank setup (to prevent fuel starvation when cornering, etc) in the boot with a lift pump or pumps to get fuel from main fuel tank to surge tank. Then have the two external fuelpumps taking fuel from surge tank and feeding the dual entry Sard fuel rail.
R.I.P.S surge tank -
R.I.P.S -
Up to around 700hp, probably stay with stock fuel rail and just upgrade to Nismo injectors, Nismo fuelpump. Or fit the Sard fuel rail
(block off centre return and use like a stock fuel rail) if you want to take it further later on or need the extra fuel.
You want injectors to run at 85% duty or less (to prevent overheating problems with injectors) if you are racing the car. So 85 / 100 of say 800cc injectors = 680cc. 1cc = roughly 1hp, so 680hp.
Then find a fuelpump or fuelpumps that supply slightly more hp than injector max HP (800hp) to be safe.
