I had a powershot NOS system on the shelf for years
P/N 5001
125 HP
(I wanna be conservative with the NOS)
I decided to use it and I was going through the parts and i seem to not have any flare jets?
P/N 13750
I tried locating on the NOS site but no such part number exsist?
where can i get them or do i have to upgrade the plate?

The Powershot kit is not adjustable, there are no replaceable jets. It is set for 125HP and that's it.

the kit specified an assortment of jets for fine tuning and there is a pocket in the plate for fuel and nitrous jets?
I even looked at the replacement plate and it said the jets are included?

The Super Powershot kit is adjustable, the Powershot is not.

From the instructions for the Powershot kit.

Chapter 1 Introduction to your NOS Nitrous Oxide Kit
1.1 General Information
NOS Powershot Kit is intended for use on domestic V6 and V8 engines using single 4V Holley or Quadrajet carburetion.
Horsepower and torque increases will vary with engine displacement and modifications. Approximate power increase estimates
can be made, based on the mass flow of nitrous oxide into the engine.

The NOS Powershot is a non-adjustable system, preset at the factory to flow enough nitrous oxide for a 120 to 130 HP increase,
in most cases. The Powershot kit is ideally suited for engines, which have not been modified internally.
A typical consumption rate for this system is 1.4 lb. / 10 sec.
