Bryan,
 
OK, you switched gears on me.  I thought we were discussing rotaries, not Subarus.  (I haven't said anything about Subaru, pro or con).  Last time I checked, Subaru engines had pretty much the same number of parts as any other recip of the same cylinder count.

almost just install a good mid time certified engine or buy a new one

that that is going wayside what is the point.
Not that this has anything to do with Rotaries but we have 2 aircraft
with subaru engines on them in our chapter.  One crashed because the
computer that controls RPM has to be faked out to think its not
running high RPM and somehow that didnt' work, the other has less
than 40 hours on it, tried to quit in-flight once and just recently
had to be torn down and rebuilt because they found rubber and a
spring in the oil.
