Nitrous for gas mileage
I have been told that injecting nirtous oxide into the engine provides more complete combustion of the gasoline. And while it may not be more cost efficient, THEORETICALLY would using a very small amount of nitrous trickling into the engine yield better gas mileage?
And THEORETICALLY could I put nitrous in my Insight for that purpose?
Is there any possibility whatsoever or am I dreaming?

This is the wildest justification that anyone has come up with for putting an S2000 under the "juice". 
This car was designed to run rich as a normal state of things. If you blow nitrous, you'll lean out the mixture, the O2 sensor in the exhaust manifold will sense this and I think will put in more fuel. Your fuel economy might even get worse. Rather than installing nitrous, why don't you consider using something like a VAFC and leaning it out that way? You might get better fuel economy AND make a bit more power.
Besides, this car is already a fairly fuel efficient one anyway. How much better do you want it considering it's a high performance car that can outrun most other cars with V-6s and some with V-8s? I've never had a high performance car of this calibre that gives me mid to high 30's mpg.
If it were me and I really wanted nitrous for the sake of adding more power and to be able to say "I have nitrous", I wouldn't mask it by saying I'm interested in fuel economy.

A little statistic I read on How Stuff Works - an engine running at 4000rpm uses approx 0.2 liters of gasoline per minute. An engine running at 4000rpm using only nitrous would consume 10,000 liters of it per minute.
I'm wild-ass-guessing that every $1.00 you save in fuel mileage using nitrous (assuming that the you save any in the first place) would cost you hundreds of dollars in nitrous bottle refilling costs.
Besides, nitrous is typically only used during full throttle applications. Unless you're going for some sort of mileage record for a hybrid vehicle during a top speed run on the salt flats, I don't think you're going to see any improvement whatsoever.
