dont just read here, Wikipedia, HowStuffWOrks and a buncha other sites hvae loads of informations, along with other forums. You need to READ READ READ, figure out what you want , then research the specific components of your kit, research some more, then install it youreslf. The only stuff that isnt bolt on/plug n play are the BOV (whihc is a little weld) and the oil pan tap. There's some cutting/T'ing of lines and whatnot, but otther than that its bolt on, you should be able to do it yourself.

Piecing together your own kit will give you results speficially how you want them, and its a custom kit nobody else has, and in the end it'll be worth it when everything comes together

and remember, the tune is the biggest part, dont use the GReddy blue box/emange, OBD1 chip/tune ftw
