42lb or 60lb injectors will be good. If you get 60lb your tuner will tune them for whatever fuel psi is needed. There are a couple of guys on here selling new 42lb injectors.

The injectors won't be able to flow the amount of fuel needed and they will max out easily. Look up some of Toms post about injector sizing.

Yeah the boost a pump is exactly what it says....boost A PUMP. Your fuel pump. All that will do is increase the voltage on your fuel pump to pump more fuel but if you don't have big enough injectors for the amount of fuel the boost a pump and fuel pump are pushing, then there's no point. Gotta get bigger injectors.

i dont have to buy a bap do i? i only need that if i want to go more whp or boost.
No you can use your stock fuel pump alone. Stock fuel pump will hold 300whp or more. Ask 03OrangeSVT. He's using the whole stock fuel system (minus injectors) and he's making well over 300 hp.

Oh ok my bad. Must have read wrong somewhere.
But your not wrong about the stock fuel system making 300whp.

With the right injectors, and right tuner. The tune can increase fuel PSI that is able to safely make 300whp with, I'd say #60 injectors
