If you've ever heard the phrase, "There's no replacement for displacement" or Enzo Ferrari's famous "Turbos are for people who can't build engines", then you probably think turbos suck. Well, they literally do, and the truth is that Enzo Ferrari was talking about aerodynamics, not turbos, when he made the above opinion known. Jeremy Clarkson once said about turbos that "exhaust gasses go into the turbocharger and spin it. Witchcraft happens, and you go faster." Ultimately, the performance benefits are obvious, as are the economy advantages, but unless your engine is designed to receive boost, leaving things stock is always the better option.
