Here's why:
* Turbocharged engines generally require fuel injection. Carburetors are not capable of delivering the precise fuel-air mixture needed for efficient combustion under the varying pressures and demands of a turbocharged engine.
* 1990s Volvos were known for fuel injection. By the early 1990s, most car manufacturers, including Volvo, had transitioned from carburetors to fuel injection systems for improved performance and fuel efficiency.
Therefore, a 1990 Volvo with a turbocharger would almost certainly have a fuel injection system.
