As the originator of the thread I'm not sure its wandered. It did start out about the Tubaru queue based on my interest in a water cooled roadster on a shorter timeline than the likely timeline based on the SAW backlog (and I wanted to know if Steve would need to pucker up :)).
I think discussing other similar water cooled/FI driveline options is fair game as that is one of the key differentiators of SAW but a few others are getting in to the game.
