well...that all depends what he wants to do: N/A, Turbo, Supercharge, Nitrous. If it has the B18B1 (LS) motor then he can do turbo for max power - superchargers don't give good power on those weak motors. If it has the B18C1 (GSR) then he can do N/A, Turbo, Supercharger, Nitrous but turbo would be best again for high horsepower. You may have to lower the compression depending on his power goals. And finally if its the championship white 97 Type-R :drool: i'd just leave it alone and do mild bolt-ons OR you can make that an N/A monster or use nitrous. Turbo and supercharge may require replacement of internals to lower the compression.
