From what I've seen, two strokes and turbos are a waste of time.
a properly tuned expansion chamber will 'super charge' a two stroke.
But can't see how it could eliminate inlet blow by.
For that you want a reed valve.

I was implying that the turbo be placed after the expansion chamber so that when it reaches certain rpm it partially eliminates blowby by increasing specific pressure in the exhaust side, partially countering the pressure from forced induction, im more serious about a small tractor turbo, a cheap one, and the reed valve would prolly do wonders in this application. I aint askin if its worth it, im askin if its possible. this is my dream if I win the lottery :p

2strokes can be done just remember man wouldn't be flying or breaking the speed of sound today if the few had listened to the doubters (those who said it couldn't be done)

what you need to ask yourself though is why do you want to do it turboing isn't as simple as some people make it out to be meaning you need to find the right turbo size
(exhaust wheel an intake wheel sizes etc)
how you will get oil to the bearings with a 2stroke that has no oil pump etc etc

if you still find yourself wanting to do it go for it but do your homework

Yes, it can be done - anything can be attempted & this has. The "doubt" is in regards to the long known limited overall effectiveness with two strokes in general, that it's pretty much pointless in an unreeded, piston ported two stroke such as the OP referenced for the reasons previously mentioned.

In this instance it isn't a matter of attempting to do something that hasn't been done before in spite of the doubters, it would be attempting something that's been tried over & over again by those with far more skill & resources then we, for as long as two strokes have existed.

You can still try to bludgeon nails into a board with a screwdriver even though others say it's wrong, but better still to offer a hammer & see.

It's just the wrong tool for the job is all, far better to suggest what's more likely to succeed - such as any number of the small four strokes ;)
