Almost ready to go with my JRSC in my integra.

couple quick questions regarding fuel delivery and intake.

are aftermarket injectors, fuel regs, fuel pumps necessary or can the stock gear run the kit at 6psi?

I have access to cheap Sard regs, Walbro pumps and injectors so using them is not an issue - just want to know if I need to or not...

Secondly
Intake, is there an intake that is known to work better - the current intake on the car is a shortram with cold air box and cold air feed from front bumper duct.

Again i have access to a bunch of other types if something else will work better.

Your comments please.
