Wouldn't a turbo only work if you could also increase the back pressure of the expansion chamber as by design a 2T engine has both ports open at the same time, so any increase in pressure in the manifold and hence during primary compression at the crank would just blow even more mix into the expansion chamber. You would have to somehow increase the back pressure wave to "stuff" your extra mix back into the cylinder between the inlet and outlet ports closing. I think this would just blow unburnt fuel out of the exhaust and give no more performance.
