I've come to the point of my build where I have to make the major decisions about engine and prop. I find myself overwhelmed and unarmed. There are several companies to choose from and most of the websites are not very informative. At least not for the amateur builder. There are sooo many options to choose from. How do you guys make these decisions? Where do you even start? Upgraded rollers? Cold air sump? What is the difference between B1B and an M1S? Do you go with ECI components or opt for Superior? And why?
I do have some of the basic choices narrowed down but still need help. The engine will be new. The engine will be fuel injected so some systems require a return line plumbed in. I currently fly with a purge valve but is that really needed? I would love to have a lot of HP but I don't feel the need to spend $5000 plus extra for 20 hp. I want to ensure the setup can handle mogas... I worry the EPA will win out and rid us of 100LL. This means I want to avoid higher compression pistons right? I will be going with dual PMags. Why doesn't Lycoming offer options on the experimental engine line? I will also go constant speed although I don't like the extra cost I am currently spoiled and don't want to go back.
So next you have to choose a manufacturer. Where is the complete list of engine builders? Where is the engine buying guide? There are some great reviews from people on this site but what does that really mean? Does it mean personal support during setup and break in? Does it mean they have a great warranty and will take care of you? How would they do that exactly? All these companies are FAR from me meaning the engine will have to be shipped to them for service. Doesn't sound all that feasible to me. So does that great warranty really hold value?
After you get all those decisions made....you start all over with prop choice. Ugh! Venting over....for now!
