I would install a Carls Helix. The performance and better belt life is well worth it for the one year. Anybody that says leave the stock clutching doesn't know what good clutching is.
I'd also add an extra 10 gauge ground wire from the computer ground to the engine. Any compromise in the electronics plate and the chassis (flexing) and POP goes the weasel. The factory ground system was obviously not designed by an actual E.E.
A PCV is an excellent way to make the CFI run and live like it should and I would guarantee you'd be able to sell it when you decide to go turbo. I wouldn't run a non ported, non turbo'd CFI without one.
