I had been thinking about modding out my Evo like the one in the "tricking out a hot car" or something like that segment on the 2F2F DVD. You know, the one they warn you not to try and duplicate because its not meant for street use. The one that puts out 500 HP, does 0-60 in under 4 seconds and runs the 1/4 mile in the 9's But what makes a car illegal for street use? The HP or what? and does it change from state to state? Just wondering if anyone has a clear definition of what is street legal and what isn't because I have never looked into it, thanks.
