Im wondering what size injector nozzles I can get for my LBZ using the stock cp3 pump/lift pump.
ATS has +40hp, +80hp, and +100hp options
At what point do I need dual cp3 pumps?
Will I need a lift pump, and if so big/whats a good brand?
Would a PPE fuel rail shim kit help me skate by without having to buy a whole new fuel system to support the injectors?

Any insight is MUCH appreciated

 

What mods do you have now?

 

Do you use EFI Live? Without it, nozzles will be a waste. I would suggest a built trans before nozzles also, and you will benefit from a lift pump before nozzles as well.

 

You can support 40hp nozzles along as your moderate with your driving and tuning because it will drain your rails even with a shim kit from PPE. You'll def need a built trans like mentioned before then you'll need a lift pump to support the new nozzles. Now once you install the 60hp or better you'll def need a twin cp3 setup to hold the peoper rail pressure. EFI Live is a must with aftermarket injectors reguardless of what you do to the fuel system.
