A guy on the Legacy GT mailing list mentioned it last year. I wrote him and he offered to sell it to me. I guess he bolted it on the car with no prep work at all. He even had a tank full of 87 octane. He said the power rush was addicting and he blew the engine in less than 24 hours(the dealer fixed the engine under warranty and never even knew about the sc kit). I don't plan on making the same mistake.
