i'm about to get a 2000 Integra GS (B18B1) and i'd like to eventually turbo it. i don't know all that much about turbo yet though, so i have some questions.

question 1: i'd like to get intake and/or exhaust for it soon, but then i don't want to waste money on something that i won't be using after i turbo it. if i got an aem intake would that be taken off after i turbo it? and also, i was planning to get the greddy evo2 exhaust system, but will that exhaust go with boost or would i have to change it?

question 2: the engine has 58,000 miles on it right now. i know it'll be a while before i turbo it, so it'll have even more miles. should i worry about replacing any engine parts before i turbo it? and if i should, which parts would need replacing more than others?

that's all i can think to ask right now...any help's appreciated.
