I agree. I hade to water heat the carb to turbo adapter. Without the heat, the idle was like a big motor blown gasser. Surging up and down. The adapter had frost forming on it. My adapter was just a 3 inch "log" with a plate welded to the top for the carb. All I did was epoxie a piece of copper water tubing to the bottom of the adapter, and connected to the heater hoses. No more ice, and the idle smoothed right out.
