Doesn't a turbo effectively increase the engine discplacement?

        Even if the 5l is made out of two 2.5l engines? (m20+m20=m70)

          But they were run as two separate 2.5l engines.

              I'm just sayin` that total displacement is irrelevant, it all comes down to dimensions of each cylinder.

                So how would the displacement of 2 2.5's compare to say.....

The air still is in "0" displacement and the jet turbine is pushing air in the "-" direction causing, by laws of physics, to push in the opposite "+" direction. Think of the conveyor belt as a useless piece of information in a story problem back in school that doesn't matter in the calculation you have to do.
                  technically, neither are moving therefore 0 displacement.
