Always wanted to know, how these fancy engine sounds come into being.

Is it generated on the fly? If so, how do all these little quirks appear there (like intercooler sound)? Or is it pre-recorded, and if so, how does its pitch changes?

I would imagine they would just record a car's sound and map it to its rpm, then the game just recalls the sound for whatever RPM the car is running at. They would just have to have enough different sounds to make the pitch change between RPM unnoticeable.

Sounds are recorded using real cars on closed racetracks. Games have huge development budgets, often topping $10 mil. There's a reason for this.

Here is a post describing how this is done for Forza, for both engine noise & crashes:
