Last year I started planning and collecting parts to build a custom 2.7L turbo engine off of a 911/85 (1977 2.7L S) since it has the 47mm 4 bearing cam towers, aluminum chain housings, etc, so I could put my numbers matching '75 2.7L on the shelf. I found a running engine with 278k miles on it
in Atlanta and brought it home, but it had great compression and ran so well that I decided to dress it up, put it in the car, and run it N/A with my old rsr style headers and some glasspacks, keeping the CIS. I dressed it up like I had the turbo engine and installed it, been enjoying it like it is since.
I don't know that I will turbocharge it again, as I had a once in a lifetime opportunity to chase my dream and buy a 934/5 race car replica shortly after that which had been off the track for nearly 20 years. It has been an incredible project and it has been giving me my turbo fix since... I am currently in the process of putting the 934 header/turbo setup on it with ITBs. It has a 3.4L based of off an '88 3.3L 930 engine.
