I'm sure the Honda core is bomb-proof but that's a very small part of the puzzle. Just about every modern Japanese four-banger will run all day because they've had about 60 years of design refinement. I doubt the same can be said of the gear drive on this conversion. It's not like this is the first auto conversion to come down the pike, and I'm sure it won't be the last. I agree the price looks attractive, but there is a reason: no track record. I'll let somebody else put the first 50,000 hours or so on one of these before I jump in.
