Back when I first got into 914s in the late 1980's it was two 914 owners who were local to me (Southern WV region SCCA) who were very instrumental in my love for 914s. They were...
Franz Workman
Mike Dudley
Unfortunely both passed away years ago (and at early ages). Franz gave me my first ride in a 914 and Mike was always willing to help answer my endless questions. I wish I could tell them thanks today.
This was also in the pre-internet days, so I also feel that George Hussey and Auto Atlanta was a huge help to me. I fondly remember reading and rereading the pulp paper AA catalog.
Recently it has been people such as...
Eric Shea
Rich Johnson
Mike Lesniak (Dr. Evil)
Just like RJMII, I have worked with Mike recently on learning his secrets of transmission rebuilding and will be starting up my own business in June.
Lastly the entire collective of people on this and other forums (such as Roadglue) have been great sources.
