I think there are turbo kits available for the 4g94 you might want to PM ssp-lancer or read his thread a few down.

It takes a lot of time and money to turbo a non turbo'd car and like Ender. said, in most cases the car will still be slow. I would either suggest swapping a 4g63 turbo in or getting a new car, that is if you want to be fast.
