 Colyn,
 This engine is widely used in the turbine certified/commercial
 helicopter market.  The engine is modular meaning the compressor,
 reduction gearbox, turbine, fuel control, governor, etc all have
 different overhaul intervals.  So it is somewhat difficult to say what
 the total overhaul price is.
 
 12 years ago we used to have our own in-house overhaul facility and the
 costs at that time could range from $45K up to $250K depending on the
 internal condition of each component.  Especially the turbine.  Overhaul
 only covers the normal labor and "must replace" parts.   There are
 always other parts that are needed but not allowed for in the "normal"
 category.
 
For an airplane application I think Soloy Conversions would be the best
 source for this information.  I know it is very expensive relative to
 the pistion engines being run now.  This is also why the Walter turbine
 has been so popular.  Because of it's European "third world" origin and
 relative lower costs.
 
 I noticed a few of these engines for sale at barnstormers.com
 
 The Rolls Royce 250C20R engine has a max horsepower of 420hp and max
 continuous of 370hp.
 
 Silver Eagle has also used this engine in coverting the Cessna P210 to
 turbine.  You could get information on them from
 www.propjet210.com

 Bryan,
    Do you have any idea what the overhaul cost is on the RR engine?
