Well like has been said before you can get all new internals and cams that are specific to boost applications along with larger injectors and colder plugs also porting and polishing your head/heads and the intakeand exhaust manifolds never hurt with either an NA or FI engine aswell as oversized valves. Dished pistons for example are great for boost aplications to lower the compression ratio down to roughly 8:1 - 9:1 idealy but (like in my case) 10:1 is very doable but no more than 10 pounds is really recommended. in an NA motor you might go with raised pistons with valve reliefs to get a higher CR. I am assuming you would be interested in doing this on a Honda engine (possibly a prelude or ITR) I would say you can keep your engine mainly stock but get bigger injectors and colder plugs then get the computer fully remapped not just chipped. for a little better response I would even change the cams, then you will be in a good place for a Honda.
