Sega GT 2002 Cheats

If you lose the ''Sega Drag Racing'' event on a day ending in ''5'', (ex. 125, 135, etc.) then the next day, ''Nitro'' will be available in the Used Parts Shop. Once installed, you can use it by pressing Y. You can only install it in one car, and can only use it once. After that, you can't use or buy it again.
