996 Engined KG

I know that Herr Bader has shoehorner a 993 engine into a Ghia, but would a 996 engine be possible? What about a Twin Turbo model? I've been looking and oooking for like 6 months now, and I've only been able to find a vague reference to the 996 engine width. Does anyone know the overall dimension of the 996TT engine (lengthxwidthxheight)? Thanks a bunch
