Ok here's the deal. I have a 1989 Regal Limited. I have a nice sound system inside. Since I am getting rid of the car in a year, I want to sort of use it as a project car. I put in my own modified intake and am about to get an exhaust. What other modifications would you say I can do? Thanks for the input. :smoker:

is it a quad4, 2.8, 3.1 or 3.8?
