This may sound like prejudice on my part but as I talk to a bunch of folks
about conversions here is what I have heard about the Subaru conversion:
Ground clearance is reduced by a good deal.
Folks have had problems with the KEP adapter plates cracking.  They said
something about the adapter plate bearing all of the load of the engine.  I
would think that there should be an engine carrier for this conversion but I
don't know.
Have fun with the wiring!
Supposed to have decent power and reliability but I don't think anyone has had
one installed for longer than 20k miles at this point so time will tell.
