stop using detroits as a basis for a argument that 2 strokes can be turbocharged or supercharged. they are a completley different beasts, they don't rely on the piston to create the bulk of their compression, that comes from the blower, and turbo combo, hence the need for forced induction to work. basically the air/fuel mix is forced in through holes on the side of the piston that correspond with holes in the cylinder jacket creating a cleaning and charging cycle in one, plus diesel fuel needs a much higher compression ratio to ignite, another reason for the use of forced induction.
now im not saying it can't be done, in fact i believe it can, if the turbo attaches after the expansion chamber and the chambers size and taper takes into consideration not only the extra restriction created by the turbo but also the false sense of greater cubic displacement created by the extra charge in the cylinder. would take ALOT of research but could be viable.
