Eh...I guess I prefer useable instant power. Maybe if it was a small ball bearing turbo. Granted, almost all of my track driving experience is from the Nurburgring where there arent a ton of straights but TONS of elevation changes and corners
I drove one in Geramny for a few days....it made me fall in love with AMG. I've legit looked at E63s several times since coming back. That has got to be one of the best sounding engines ever made....like a roided up Messerschmitt still fighting the war
The ultimate frankenporsche that is doable is a Cayman R with an aluminum block LS. Porsches best chassis with the easy, reliable, and cheap power from a lightweight LS. Wipe the floor with almost everything
