Let me preface MY posts with the statement that they ALL concern use in a KR, not other aircraft. In relation to the Subarus, the units that are in the proper weight category for use in the KR are under powered and do not perform as stated in ads. EA81 and EA 82 as an example. To get the rated hp requires use at an rpm that causes these engines to have a very short life. The new engine that Eggenfellner is now using may be a wonderful innovation, and very reliable, and great for use in an RV something, but are WAY TOO HEAVY for a KR! They fall into the category comparable to O-360 or IO-360 both in weight and power. They DO NOT compare well to use in KRs. KRs and Sonex aircraft require much lighter power plants, with less rated hp.
Secondly, a quick check of my posts concerning late model engine usage cautions against using any engine the operator pilot is not intimately familiar with. You have to work on it, troubleshoot it, maybe in the air, and repair it. You better know ALL about it, not from somebody who tells you about it, but REALLY understand it, or else fly with something else. I intend to fly at some point behind modern fuel injection, but I also have over 15 years experience working with auto fuel injection, and will use something I know well. I will not instruct others, nor will I publish my results because I do not hold myself out as an "expert". But I do understand the animal, and know its limitations. If you do not, I suggest you fly with something else. The REAL keys are reliability, ease of maintaining, and sufficient power to provide a margin of safety beyond minimums. Evaluate by looking at specifics of each suggested engine, not generalizations. Not timing chain or TIMING BELT is easy or simple to inspect or change, or you don't have an appreciation of the work required. I cannot tell you how many timing covers I have seen off the engine, with the owner believing nothing is wrong. For starters alot of the timing marks are on the cover. Second the cover was designed to prevent dirt and debris from damaging the belt, HELLO! REALLY study the engines please... Ok, back to my motor mount.....
