It is hard to tell someone how long their engine will last.
It depends on so many variables;maintenance, how hard you drive, how well everything was installed, environment.
The edelbrock kit was designed around a low boost, almost stock system that is trying to retain all the reliability of a stock honda motor. Unless you try to go beyond the capacity of what that kit offers you, you, in most liklihood, will not mess anything up within a few miles.
Nearly every *stock* motor can handle SOME sort of forced induction, it all depends on how high the boost is, compression ratio,and how well the head and bottomend is built to handled the extra power.
Take the subi or evo, they are both built SPECIFICALLY for a turbocharged engine. They have specialized intake manifold runners, exhaust manifold, and a turbo that satisfies the needs that both companies were trying to achieve, a low lag time fast spooling motor that puts out decent horsepower numbers.
As a general rule of thumb, you add ANYTHING that adds more complexity to something, the more likelihood there is for something to break, that is just how the universe works. If you are not a complete idiot and you take care of the motor and turbocharger like how was recommended (more frequent oil changes.. etc) then it will not end up blowing up in your face barely any quicker then a stock honda motors dies, and that is usually a very long time.
In all honesty, Honda motors do not handle boost as well as some other stock cars. Honda power is built around long intake runners, high end power, and high compression to make it all tick, but this is NOT to say that Honda motors are in any means the wrong motor to pick for a boost fiend. I am just trying to emphasize the point that ANYTHING will last, given that it is well engineered, and the person using it is a conscious person and takes the proper precautions (maintenance).
Also..just fyi, hotspots are generally spots in the piston head which are warmer then the rest of the surface area, thus promoting detonation.
Also, another thing... Honda put VTEC there for a reason, using the upper RPM range will typically not promote more wear, its usually the full throttle lower rpm where air is being rammed into the engine by atmospheric pressure that typically harms them. Another example of using engineering how it was built, Honda's were built as high revvers who make alot of highend power for a reason
