To all buddies how colaborate I thank you a lot. Very nice and clear answer. No way to choose another one.
Concerning to the space for installation, the K140 is 4.5" wide like the olds P-80s that were used as reference for Elan design. The turtine itself fits but KT has a wide bracket (wider than usual) and I would need to cut off part of the 'bracket ears'... I will think about.
