My dad spent some time in Germany in the late 50s - early 60s. He was on the autobahn with a friend at one point doing 80mph when a Volkswagon Bug police car flew by at nearly 100 mph. Supposedly they used a bug body with a Porche engine and Porche suspension.
Can be done and has been done numerous times. Usually it's the 914/4 engine with a greater bore, replaced cams, added supercharger, ...
Besides replacing the engine and the suspension, the engine stilts need to be replaced, undercarriage needs to be strengthened, the roll cage is usually installed, sides of the body are stiffened, brakes have to replaced, transmission should be replaced, and then you have one not-quite-conventional bug. Only for car lovers, that thing. It is much cheaper to just start with an early-80s 911.
