All of that is "just money"
It is mind boggling the number of things that can be done to a 911. If I had the unlimited bucks I would love to have a Ruf Yellowbird.
Ruf CTR - Wikipedia, the free encyclopedia
I think that is about the max evolution of my model of 911. A curb weight of only 2,535 pounds (1,150 kg) combined with the CTR's high output of 469hp gave the model 0-60 mph in 3.7 seconds, 0-100 mph in 7.8 seconds, 0-125 mph in 11.4 seconds and a top speed of 211 mph (340 km/h).
All I need is a spare 300K or so.
