I was wanting to know how much HP the stock fuel system will support? What injectiors are in the car stock? How much power will the stock fuel pump support?

Thanks,
Kyle~

I believe it'* 21lb. injectors. If you go with more boost, it'* usually a good idea to go to 24lb. right off the bat, particularly if your going with hotter-firing coils and wires. I know there are some in here moving to the 30'* range...

Burgandy Boat, jeffrey10x2, or DrJay can answer that one precisely. PM one of them if they don't show here...

Any Nitrous system should be the last thing you do...

One of the other mods on BC here: Allmachtige, he successfully installed and uses a NO2 dry shot system. He is your best resource

Instead of going a higher injectors you could just increase the fuel pressure on your injectors. There really isnt a point of going to higher injectors just cuz you think you need them, all your doing is wasting you money. Just like adding a MSD box if you dont need it. Your getting a bigger spark but that extra spark isnt doing anything. I would go ahead and upgrade the stock fuel pump. Especially if down the road you are going to stick to your turbo plans.
