here's the deal, I have an 88 5.0 mustang.I have had the car for over a year now. I am planning to ad a kenne bell 2.1L super charger. the 6 psi kit. I need advice on what other engine up grades I will need to install the supercharger with? the car and engine is bone stock. I have the capitol to buy the kit and most of the parts. I just want to be sure before I buy the super charger kit. I don't have to buy performance heads or build the bottom end up at the same time. I do have plans on doing a top end kit in the future.
