I looked into doing this a few years ago and here is what I cam up with as far as parts.
downpipe, CAC pipe, intake, oil drain.
I ended up going with a ATS 2-piece 3rd gen manifold instead. It's nearly as even as a 2nd gen manifold and let me keep my downpipe, OEM intake (hard to beat), and oil lines. . Really I am not sure you will see much of an improvement on a 2nd gen over a ATS or BD aftermarket.
