As for the BHG issue, get an HKS metal HG. Problem solved. I don't know what you mean about hard to find a Turbo Supra. They're all over, seems like there are more turbos than NAs. The Supras have timeless looks. I never get tired of seeing them, even in stock-bodied form. You can make lots of power from the stock motor, and you won't get tired of the targa, ever.
