Before I go any further, I should note that there are professionals out there that do this for a living, charge a modest fee for the service, and do a much better job than a shadetree mechanic. Prominent figures in the world of SU ressurection include: Rhys Kent of Island Automation, Advanced Performance Technology, Joe Curto in New York, Chester Gillings, Paltech, and Z-Therapy. Prices and individual experiences vary; I can say that I've spoken with Rhys Kent on the phone, read his posts on Brickboard, and would send him my carbs in a second.
That is, if I weren't a total cheapskate. As my friends and relatives will attest, I am a true cheapskate, and in true cheapskate spirit, I forged ahead with the work myself.
