Is there any information available about the new SMA jet fuel engines
that are being offered for the C182?

Prowl around http://www.smaengines.com .

I'm curious if maintenance would be much of an issue. Are there many
shops that can handle working on them?

Not in the U.S.. There's only one or two 182s flying with that engine in
the
States. The French STC was granted only last July, and the company doesn't
expect the FAA to grant an STC until later this year.

Is it a replace only like the Centurion 1.7 on the Diamond airplanes?
Or can it be overhauled to get flying again?

They're targeting a 3,000 hour TBO. Since they use the term TBO, not TBR,
it
seems the company intends to support overhauls.

Cost for an annual?

As much as you have. :-)
Seriously, SMA claims maintenance costs will be lower than gas. Since that
tends
to be true of diesels, they're probably right.

How would they perform at high altitudes? - Colorado rockies region for
example.

Should be about the same as a turbocharged gas engine of similar torque.

Drink is the curse of the land. It makes you quarrel with your
neighbor.
It makes you shoot at your landlord. And it makes you miss him.

Yea, and put a turbo on that Diesel Engine get better performance and better
fuel economy
