@SleepyS14se...
I purposely did not post my opinion in this thread with respect to my personal choice(s)... Wanted this thread to start as an unbiased conversation topic where the folks who DO know these things can further the discussion for the benefit of all. To reiterate... Unlike you, I am not familiar enough with the inner workings of ANY motor to speak competently on this subject. My particular choice of internals is in my build thread; and in random recommendations in the tech threads. Rutger and a very select few others are the ones whose expertise I rely upon to steer me in the right direction. If you'd like to converse with Rutger, open an account at
www.zeroyon.com. That's the forum started/owned/operated by the American guys who live(d) in Japan & learned these cars at the source. Immense amount of knowledge there.
