Well here is my two cent's. There really is two questions you have to ask yourself. One, is this your primary driver? Two, how fast? I learned the hard way when I was younger dumping alot of mod money in your dd is so much fun. But it suck's when you break it and there's no one to take you to work the next morning ,and you have to do a late night repair job. Don't get me wrong though! A little go with a cool Idle may be what your looking for. But' if you get addicted to wrenching and speed,buy a project car.It's just easier.
BTW Slowgreen99 suggestion's a good setup ffor the money imo.
