Gil,
I really don't have any idea what an O-200 costs used.
I have never looked because it was never an option I considered.
So let me start this by asking, can you get a rebuild able O-200 for about $200?
I would think not but you might get lucky.
Then we can look at the cost of rebuilding services and the parts associated with
the rebuild.
I don't know what it costs to re do the heads & cylinders for the O-200 but I can
say that for about $300 you can get a set of Corvair Cylinders mailed to you
that are bored and honed. (that's all 6).
A set of MagVair forged pistons are only $450 And this includes the rings.
The New Billet 4340 Crankshafts are $1195.
I have no clue what a new Crankshaft for the O-200 costs but I would bet it's a
bit more than that.
I guess my point is that your money goes farther on the Corvair than it will on
the O-200. Sure you could spend the same amount of money on each engine and have
two working engines but you would not have two apples to compare.
you could do the absolute minimum to make the O-200 run and spend $x?
But if you were to spend the same amount on a corvair it would go farther & you
would have an engine that had many more mew parts on it and dare I say more reliable?
One place where the corvair really shines is the cost of up keep and when it comes
time to over haul.
Building the initial engine up & converting it is far more expensive than the cost
of an over haul.
for example:
Replacing your spark plugs on the Corvair; 6x $2 = $12.
Available at your local auto parts store.
And so on..
Look at these associated costs as well and you will see the Corvair shines even
brighter.
Not to mention the smoothness of the engine.
I have never her anyone accuse the O-200 as being smooth.

I'm no expert on engines, auto conversions, or certified. I really don't have any
problems using converted engines such as a Corvair or VW. I don't like the
idea of two stroke engines, or high revving four strokes that need some type of
prop reduction. To me high RPM bring to mind additional wear and other problems
associated with increased forces due to high speeds. I know there are piston
engines that run in excess 10 K for long periods of time, but I'm just not
comfortable with an engine turning over three thousand RPM in my airplane. I
have seen 0-200 engines blow off a cylinder in flight, so I am under no illusions
that there is a perfect engine to turn a prop. The use of a lower RPM direct
drive engine is strictly my personal choice based on nothing but my gut
feeling. I also am under no illusion that I can build any type of engine for a
few hundred dollars, it just isn't in the cards. I am in my sixties, have been
a PP for over thirty five years, with several hundred hours of PIC. I am looking
to build a plane that will last me the rest of my flying days, so I want
to get it right. What ever it cost, it cost, I just don't want to make a ten thousand
dollar mistake.
The Corvair engine looks like a good alternative to the other 100 HP engines out
there. You say it is much smoother running that an 0-200, and less expensive
to rebuild. I have no reason to doubt what you say. The addition of additional
support that the fifth bearing will provide also makes a lot of sense to me.
From what I have seen in different ads, you can purchase a mid time 0-200 for
around 10 thousand dollars. That should be good for around 1000 hours of flying
time, shouldn't it?. What will a comparable Corvair engine cost and what will
the operating cost be?

Gil,
For $10,000 I think you could have a fresh Corvair with a new crank and maybe also
5th bearing.
I am not entirely up on the 5th bearings but that would be my guess.

Hi Gil,
Just a quick note regarding the Corvair. I've only got 25 hours on mine but
it is so smooth that when I first flew it, I actually was running on only 5
cylinders because of a spark plug wire that was left off and I never even
noticed it during flight! It runs even better when firing on all six :-)
As for maintenance, I haven't had any yet but I did have a Mooney with an
O-360 (with only 150 hours on the engine) that required a new piston, rings,
plus labor that ran me about $2500 (If I had done the install, the cost
would have dropped to about $1200, although I couldn't have done it legally
on the Mooney). On my Corvair, I would be able to replace the piston, rings
etc myself for about $100. I just replaced all the plugs on my Corvair for
under $12. The Mooney would have been about $300!
I'm running without the 5th bearing and my cost was approx $8,000 for the
engine.
Anyway, just a small comparison between a certified and an experimental
engine. Hope it helps.

Yep, BUT the 0-200 group doesn't hold a candle to this group of guys,
there are some INTERESTING doods here.

Are we starting to enter into the same price range as a used 0-200?
