Make it two gallon per hour. That's 10 dollar per hour. And not to

Lower fuel consumption means not only cheaper in operations, but also
the ability to fly longer legs without refueling, or just a saving in
fuel weight if you just fill her up for a certain time of flying.

That's really short term calculating. Let's say the airplane plus its
engine will see a service life of 1500 hours. Then the jab has consumed
$15000 more than the Rotax (ignoring the fact that the fuel prices will
go up). Indeed over the service life of the airplane even a 914 with
turbo is cheaper than a jab. Not to mention the selling price which is
clearly higher for a 914 than for a jabiru, if you ever choose to sell
your airplane.
That was about money. Now think about performance. Or maybe you plan to
fly only close to the sea level and the higher altitude performance
hasn't a significant meaning to you.
You liked to compare against a 914. A 912 is significantly more
affordable and consumes about the same amount of fuel as a 914. With a
912 you actually gain a lot of money over the service life compared to a
Jabiru.
Just some thoughts. (I don't care what you install in your airplane, but
I hope you are seeing the whole picture. It would be a shame if the
project you invested so much of your time in is going to disappoint to.
Apparently quite some people got very frustrated with their Jabiru, and
some even converted to a Rotax 914 and wasted the money of their Jab.
Now let's do the calculation again...)
