Sega GT Online Cheats

If you have Sega GT 2002 then use the Load File
option to load a Sega GT 2002 savegame using the "perk" feature.

On a day that ends in a five (for example, 235), go to Event Race. Enter the race, then lose it. Go back to the screen with the "Official Race", "Event Race", "Garage", etc. options. It should read as the next day (for example, 236). Then, go to the used part store. Go all the way to the end after the turbo and there should be a "???" box. Select it and buy the Nitrous. Note: You must have a turbo to get it. If you have a turbo and it does not appear, exit the screen then go back in again. You can now go to a drag race, and while you are driving, press Y to activate it.
