Go in steps...it's very enjoyable. There is excitement you'll feel as you make each upgrade to your car. I would have not been as satisfied just doing everything at once. That was one piece of advise I was given at the outset by the local tuner shop, the very same one I would eventually be using, that was spot on...they could've talked me into just blowing my money all at once at their shop but they didn't. I am glad I listened.
