I'm not sure most people knew what a turbocharger was to begin with.
There are many ways you can make an engine faster. To me the choice of "turbocharger" implies some parallel to the turbochargers actual function, extracting energy from a waste product to process input material at a higher rate.
That's true, finding someone with 10k is not as easy as picking a person at random, but it is as easy as driving to the right parking lot and picking a person at random.

Although with turbocharged engines, you can turn the power up to the point where longevity goes way down. Still, you could give people a power limit knob they could turn at their own risk to have access to the whole Pareto frontier of performance and longevity. That'd leave no room for tuners.
Is that what you the mean?
