looks like a really complete setup you have, some places you may be able to save money is the JWT fuel rail, JGY Customs makes an almost identical and just as good one for 130$. You can also get "delphi" 75# injectors that are actually identical to MSD 72# from
http://www.racetronix.com for 57.50 each. I also dont really care for your disco potato turbo choice, I think it's a shade small for a KA and just doesn't make the power it should (no offense). Finally, whats the purpose of this car? Oh, and if you get an aftermarket fuel rail, tell them your using a nismo regulator, not an aeromotive etc. the aeromotive is a ***** to use anyway (I know from personal experience).
