Sometimes I forget that E-85 is a midwest thing... It sounds like you're pretty much set though.
With the eBay turbos, a lot has changed in the past several years. Now a days they are almost exact knock offs of the real deal. The guy I was talking about is Parish8. He had the worlds fastest 99+ Silverado, Second Fastest G8, a rear mount turbo lexus and has made multiple appearances on Hot Rod Magazine's drag week. The godzilla is exactly what he used on his lexus, and he had it tubo'd for about a year before selling the car, and it's what he reccomended to me. The G8 had a Masterpower, which was about a $500 turbo when they were around. A lot of people that used to use Masterpower use Magnum now, since they're pretty much the same thing.
