After a bit more digging here is some more information I have found:

Current cost of the C182Q kit is about $77K soon to be
reduced by "at least $10K" so around $67K

Installation, at the dealer I contacted, runs about $9K.
Or about 120-hrs @ $75/hr.

So the installed price should be about $76K. Which
includes almost everything from the firewall forward.


"Normal" recurring maintenance is expected to be:
100 hour oil changes.
200 hour fuel filter change and glow plug inspection.
500 hour compression check
With estimated time at 3~5 hrs.

Annuals were - Quote:
"Your overall annual inspection will be much
less then an avgas engine by virtue of the
fact that the engine contains 70% less parts
and therefore there is virtually nothing left
to change out or replace."
So how much that will really mean ... ?

Overhaul is estimated to run around $24K+ based
on the 3000-hr TBO. So in the perfect world, I
could either do 2 "cheaper" overhauls on the
SMC or 3 regular overhauls on a Lyc or 3+ on
a TCM engine over a 6000hr life.

If you look at burning less cheaper (if available) JetA fuel than avgas
over the life of the TBO. Might save a few bucks. Also saving on price
of a few other pieces and parts (sparkplugs, etc.) there might be a few
more bucks saved. And starting off with a new prop.

So since I am rather new at this how much does an overhaul on a regular
avgas burning C182 engine run?

It almost looks like it might be something to look a little closer at.
