you should be fine with the stock injectors if you stay under 6psi. The low budget system: you can get a Vortech Kit used for about $900-1200... then a few other items and your good to go.
But if you got $3,000 to spend, then i would go with a S-trim setup with about 10psi and 24LB injectors...
or a quiet powerdyne.
You might want to take into account the shape of your motor before doing a supercharger. You might want to upgrade parts of the motor first to handle the blower
