Are turbos expensive to maintain?

As a cryptocurrency and finance professional, I often encounter questions related to various investment vehicles and their associated costs. One such question that I've been asked recently is: "Are turbos expensive to maintain?" This inquiry, though seemingly unrelated to my field of expertise, still piques my curiosity. Turbos, typically referring to turbocharged engines in automobiles, are known for their ability to increase power output. However, with increased performance often comes increased maintenance requirements. The questioner seems to be inquiring about the financial aspect of maintaining a turbocharged engine, specifically whether the costs associated with its upkeep are substantial. This is a valid concern for any potential buyer or current owner of a turbocharged vehicle.
