What's a ton of money? If you're considering a reliable supercharger, think $3,200 (installation extra).
You will have to upgrade stock injectors with the S-trim. Everything else is included in the Vortech kit. The S-trim kit on a stock engine will provide about 9 psi.
Get knowledgable help if installing the kit yourself. many of us here are Vortech owners so you can post questions whenever you need to.
Good Luck
