I juts bought a 98 GSR, it is all stock besides the 2.5" Custom Exhaust Piping. I have $1500 left over and I am not really sure what I should spend that money on. I wanted your opinions on what I should get with that money and how it would help my cars performance, I plan to turbo my car this summer so keep that in mind. I just want to know what you guys think I should get and why.I know it is not much but what would you do?
