It sounds like a possible but expensive job to me, resulting in a car that might be harder to sell when the time comes. Better to save up and buy a Tamora!
Waste of a good car? If you really want Cerbera power levels in a Chimaera it would be cheaper and easier to throw some money at the RV8. Don't forget you would also need to do a lot of work on the transmission, suspension and brakes.
