Can a Single Turbo Be Upgraded to Twin Turbos?

[DallasDella]

Single turbo cannot be upgraded to twin turbos. A turbocharger is an air compressor whose function is to increase engine output power. Without altering the engine cylinder capacity, it achieves this by solely increasing the compression ratio of air entering the cylinders. The working principle of a turbocharger is: it utilizes exhaust gases expelled from the engine's emission outlet as power to drive the turbine wheel in the turbine housing. This turbine wheel is directly connected to the compressor wheel in the compressor housing. One side of the compressor housing connects to the air filter, while the other side compresses the air drawn from the filter into the engine cylinders, thereby increasing the air volume inside the engine.
