As for the bottom, I made an aluminum adapter plate the same shape as the base you bolt the turbo to. This will seal against the O ring. Then I made a gasket to go between the plate and the bottom of the turbo. Don't use the gaskets you can buy on line. They are too thick and will squish out the side and leak when you torque it down.
