Really depends on how much you want to drop on the car mods. I mean, for me, spending all of my extra money a month on mods would be stupid. As much fun as it is modding the car, remember when all the mods are done...all the mods are done and you will want to keep modding. I would say save some money, like 5k, and do internals first, then kb, then suspension, etc. If you get the supercharger first, it will be more work later taking it all apart.
