Piecing a kit is cheaper and just as effective if you have the means.. If you don't know how to run piping or know anybody that does, then forget it, or buy used piping from the forums.
The gmr chain as he said can be found used on the forums.. But as stated, for some serious cash.. A 7/8 chain can last if you don't launch it all the time.
All I can tell you at this point is to STUDY STUDY STUDY..

Oh and btw, you don't need that stupid aluminum intake, the l36 flows just as good and it is gonna cost you less so you don't have to adapt the tb. It's a waste of time.
