On stock WRX's, the turbo doesn't spool (start making usable boost) until about 3000 rpm. After that point, with a bit of throttle, it pulls like a madman. Below 3000 rpm however, it feels like an NA 4 cylinder.

For your use, the boost kicking in at 3000 rpm won't be a problem unless you like to really mash the gas pedal when you accelerate. If you do, then the car will throw you back in your seat at a green light, only for you to slam on the brakes at the next red light (most people don't drive any cars this way).

The point is, if you're pressing the accelerator pedal down a moderate amount, then when the boost comes on around 3000 rpm, you won't notice a huge neck-snapping force, the car will just seem to have more power (which it does when the turbo is providing boost).

Will this affect the lifespan of the parts, that is, driving in streets, the frequent stops; will it take a greater toll on a turbo charged engine?
