Well I've got my college plans set, and I'm soon to selling the Si I own now (the 93 d16z6) and am going to buy a 2000 Civic Si as my new car to work on through college. Now i have a few questions on how to build it up.

First, whats the pros/cons of NA over Turbo setups. And cant you just make an all NA engine THEN throw a turbo on it??

And what components need to be changed for a turbo setup rather than an NA setup.

Also, are ceramic coated or polished headers better for performance?
