Ultimate intake & fuel system for N/A stock LS1/LS6 motor?

[VidViper]

So the autocross class I am in will allow me to change my intake manifold and fuel system (pump, injectors, rails, lines, etc). However, the motor (heads, cam, etc) must remain stock. What is the ultimate setup to give me a little more power? Bigger injectors? Fast 92? Better fuel rails? Or is this all worthless on a stock motor?

I should also mention that I have long tube headers on the car with no cats.

I would go with a ls6 intake if you have a ls1, you wont gain much from a fast 92 unless you go heads, cam. You could also port the Throttle body.
