Need Suggestions on Fuel System

Engine is being built and I need some suggestions on fuel setup.

Specs:
Built bottom end, mild head work, stock cam, ~9:1 Compression Ratio
Turbo(at least 8psi)

I am probably going to go with the Lucas 42lb injectors. There is a guy on ebay selling them for $289 and I have read they are a decent injector.

What about fuel pump? Wiring? Guage? Boost activated??????

Goals are to keep her just under 600RWHP ~575

I need details as I am not too familiar with everything I need to consider...

I have edit so I will be able to tune...

Thanks

If you're going to cap it at 575rwhp (manual) I would install a single Walbro in the tank and proper sized injectors. Unless you're on a tight budget, I would oversize the injectors (think 57's) as you will tune it anyway and it will save you money in the future if you up the boost. Over 575 I would redo the entire fuel system with dual walbros, -10 feed line ,-6 return line , rails and regulator at the rails.....alll for safe hp.

Im not 100% sure but i dont think 42# injectors will be enough to support 600rwhp. I am going with a single external Bosch 420L Pump, sumped stock tank (98 so its metal), -8AN feed, Na$ty Performance Billit fuel rails, AueromotiveBoost Ref regulator and the the stock feed as my return to the tank. Oh cant forget the fuel filter. A with what onfire said i would over kill the injectors also. I am going with either siemans 57#ers or Motron 60#ers. Just my .02

Then I need an impedence converter right? Because its over 50lb injector size? Can you explain that? Will that effect how the tuning is done? Also will these huge injectors effect my idle?

Those 57 Siemens and 60 Mototrons are high impedance.
