Injector size? Fuel pump?
I am installing ported plenum and base and siamese runners and 58mm TB. I am going to be putting more air in so I need to increase fuel too ( I assume?) What size injectors should I install and do I need to get a bigger fual pump too? Any advice is greatly appreciated!

what else is done to the motor if that is all of the mods i would just increase fuel pressure and not worry about injectors. also what engine size are you working with?

350 engine. Should I invest in a fuel pressure regulator. Nothing else done to engine except headers.

yes i would just add a fuel pressure regulator and not worry about the injectors the increased air entering the motor will not be enough to need new injectors

if you are in california a fuel pressure regulator is illegal in street machines. check your state laws, because its hard to hide the darn thing, it sits right out there.
