lol don't build it or you will go crazy and buy freaking expensive parts......... buy a kit so much cheaper then just sell the manifold in the kit and get an h22 manifold

there is a guy selling a good turb on here now for like 500 i would have gotten it but i just bought mine the other day.

EDIT: ... just now realized that my second statement contradicts my first. It really depends on the deals to you get as to what to do, the kit comes with everything, no hassles, buying part by part ensures that you are happy with everything and also allows you to build it up over time for those that don't have 500-2000 dollars laying around.
