I appreciate all the input. At the time, I was looking to source an e-shaft and thought I might would see where they are sourcing them. Interestingly enough, I just started looking up the websites for the race teams and most had phone numbers for their engine builders or engineers. So, I called them and talked to them. One guy said,"I maintain 8 engines and only have 12 e-shafts so I couldn't let any go". All the race teams were pretty nice. One team even hooked me up with their engine builder in California. I called him and talked to him for a long time about 3 rotors and what he recommended on engine builds. The race guys seem to get their eshafts from Mazda (Mazdaspeed) and I think they were $3500-$4500 each. They don't buy engines, just all the parts individually. This might be old news to most, but I found it interesting.
