I'm just learning about these engines, but had an engine builder tell me the kit he quoted me was using Superior titan parts and that some Superior parts are sold with the Titan name. I thought they were 2 separate entities but then again I don't know much about them. I guess I believe him, but would like a second opinion from the brain trust. Do they use the same parts? Got a quote from him on the Superior kit and also a quote from Titan and they were within 1k of each other.
