1, replace the knock sensor get that done and out of the way to build off from
2. get a good set of plugs and wires, good oil and radiator flush and refill
3. cat back exhaust, intake, and smaller pulley on the supercharger
4. convert to E-fans
5. build a custom CO2 spray system to drop your intake temp and build a few extra pounds of boost (acts like nitrous but is a lot safer for your motor and lighter on your wallet)
