Compiling the recent history of this 911, with these threads to start (this photo from Road Atlanta):
Between 2002 and 2003 Marc decided to part with his 911 racer to start another 911 project, and I was looking for a turn key 911 to track so the timing was right. Since 2003 I have averaged one DE each year until 2007, so less than six events at Road Atlanta and Barber combined. The 911 has been an occasional weekend car and has seen only sunny days since 2007.

At the time I met Marc I was building my own hot rod 911 and just completed the engine and transmission rebuild. I was 70% to my goal of power/weight and was about to lighten with fiberglass, when it was clear I needed to sell my car and buy this 911 as complete and track ready. Marc had already been through various engine modifications when he settled on a 1992 C2 turbo as the powerplant.
