I'm about to buy a vortech s trim supercharger i wanted to know if i need to replace the stock injectors and fuel pump if so what you guys recomend? I was thinking 38lb injectors and a 190lb/hr pump that sound right?
S-trim fuel settings?

Either 38's or 42s are likely to give you drivability problems without additional tuning. Unfortunately, Baxter is right and you're probably going to require injectors of that size. Plan on including the cost of a new mass air meter or recal, as well as a custom chip and some time on the dyno to get it all tuned correctly.
Some will say that all you really need are the larger injectors and a meter calibrated for them. Some are actually lucky enough to pull that off. The problem is that the minimum and maximum duty cycles programmed into the stock EEC are not set for injectors of that size, nor are the fuel tables (fuel ramps are wrong).
Just be prepared for that eventuality if meter and injectors alone don't get you what you want.
Final note: If you plan on installing and/or tuning this thing yourself without the aid of a good wide band 02 meter, Vac/boost guage, and in-car fuel pressure guage, you're nuts and are looking for trouble.
Good luck!

What is the rest of the engine combination? What heads, intake and cam?
I see your location is "Northport." That's not Northport, Long Island, New York is it?

Yeah it is Northport Long Island acually and right now i'm stock with a set of gt40 headders and a cold air induction to top things off. In the future i plan on going with holley systemax II but being that the kit and the s-trim happen to be in the same ballpark price wize i'm going supercharger first
