Just a general question on forced induction. Ef sedan with d16a6 all stock internals only looking for 200-250whp. Ive posted about this before so if you've seen me do it please done flame me.

Im going to be piecing it together with used or "junkyard" parts. my question is, what SHOULD i buy brand new? out of the turbo, bov, wastegate (if not internal turbo), intercooler, manifold, or charge piping?

Im kind of confused on which to buy brand new. I was looking into the t25 2nd gen turbo with either Tial bov or gretty type s.
