Dude you REALY need to read about more cars before you spend a dime. Just as an example (I am in no way saying it is the best option) For 2000 you could buy a turbo dodge and mod it into the 12's AND still have a probe to drive. Or you can buy a 1rst gen probe and be Way ahead since you have the worst gen probe made. I love sleepers and "differant" car more than any other guy on this board and I do know what is avail for Mazdas BUT you don't have a starting point. If you want to go fast buy a car that did not have the build quality of a yugo BEFORE you added 200,000 miles.
