          I have a question about alternative engines?.....Do you know much
about Subaru engine conversions?..I have found an engine a 4 cylinder, 2.2
liter, 135 hp I think..Do you know what it weighs and would it be feasable
for a Piper Cub?. I would appreciate any help or knoweledge of this...

You are talking to the wrong people :) We are all rotor heads on here:)
Once you REALLY understand the rotary you wonder why the rest of
the world even considers a piston engine :)

In all seriousness it won't work for a actual Piper Cub because the FAA will not
let you get away with it for long.

IMHO a Subaru makes a pretty good aircraft engine at around the 80 to 100 HP
level. You are pushing it at 135 HP and 165 HP and up it becomes a hand grenade
in heavy duty aircraft use.
