3. What’s an overall suggested turbo/supercharger (price range, performance, etc..)

I like supercharges. That's just me tho... Price depends what you buy 3,000 +/-

4. How can I engineer a car to apply only the front brakes? (Yes, I want to melt the back tires off)

LINE LOCK. It's an electric selonoid that goes in the front brake line. Apply the brakes, then ativate the line lock (with a button) let up on the brakes and the front brakes stay locked until u let up on the button.

wheeeew, that's all the questions I can take right now. Take it away somebody...
