997 turbo engine

Has anyone tried installing a Porsche 997 Turbo engine in their build? Can the Graziano transaxle be adapted for that engine or would a Porsche transaxle be the better choice?
TimT is building an SL-C with a GT2 engine and trans, IIRC. Ironically, the setup needed an adapter plate, I think, as the transaxle still had to be inverted.
