I also don't know if these kind of things can be done without killing the factory warranty.

A properly done supercharger or turbocharger is the route to 15-20 hp. Exhausts, filters and revised computers are good for typicaly 5-6 hp on the dyno for a Fit total and not much at less than 56000 rpm.
Nitrous of course will add speed quyikly as it wuill shorten your engine life.
There ain't no free ride.
Course substituting a K or B engine might be much cheaprer and certainly much fster. Since my 1600 CRX gets 37 mpg I don't understand why it isn't the engine of choice for America anyway..
