O.k. heres the deal. I got the s16g and hahn ex. manifold with a built bottom and top end. Fuel system consist of stock injectors, walbro fuel pump, holley rfpr. I had the 450cc injectors with the sfmu and safc. But, I didn't like how my car ran. So I switch back to the stock injectors for reliability since its daily driven. Has anyone ever used the nitrous on a turboed 420a thats fully built on stock injectors? I would go for more boost but I don't have time to learn and build the megasquirt(which is how i would do it) or buy the portfueler. I need a little bit more of a pull from my car. I was wondering if you could use like a 35 or 50 shot of dry nitrous on a the stock injectors running 8 pounds of boost. I just needed some more wisdom on the matter, b/c i have a nitrous express intercooler kit sitting here gathering dust and I want to use it either on my intercooler or in the intake piping. The only thing that I think it might do is run lean. Is there any comments or suggestions on this. I know the thread is long already but please give me some insight.

It'll run too lean with a dry kit using the stock injectors. They're probably maxed out already. You could pull it off with a wet kit though, because you can supply additional fuel with the nitrous. A single fogger nozzle in the intake pipe would do the trick and it would be easy to convert your intercooler sprayer with parts from Summit or Jegs.

Keep an eye on your boost gauge when you spray it because it'll have the tendency to spike. Also keep an eye on your A/F ratios, and if they're too high then decrease the nitrous jet or swap in a larger fuel jet.

Thanks man that answers the question

O.K. having trouble figuring out what size jet I need. Most sites have a calculator where you enter the fuel pressure, the nitrous bottle pressure, and the size of the nitrous jet you will use. Problem is what do I enter in the fuel pressure box. I plan on having a traction control window switch so I can calibrate it to activate and de-activate at a certain rpm. So what I don't understand is want the fuel pressure rise with boost? SO do I enter the max fuel pressure i will see or what. I want about a 45 shot and I figured a .034 jet will work but I get a fuel jet any where from .015 to .019 when I entered different fuel pressures. Any help would be great. This is the only thing holding me back from getting everything so i need to figure this out.

Thanks guys

You'll be activating it under full boost so just punch in whatever your maximum fuel pressure is at max boost.
