Saying they are not effective is a false statement.

You sir need to learn the definition of effective. He had an increase of 68hp. Is that more or less effective than if he put it right off the exhaust ports on a turbo manifold? I promise you he would have seen a much bigger increase if he put it right off the manifold. If he was keeping it in the low PSI range, then it's still less effective than placing it right off the manifold. Why? think about it. How much piping for the coolant, intercooler, and oil do you have to run for both setups? All that stuff weighs something. So He threw on a turbo which could weigh anywhere from 10-25 pounds. He than ran extra long lines of coolant and oil to the turbo which only adds to the weight as well as the extra intercooler piping. When as is said and done, is it worth it to spend the money on a setup like that, that will only net you 68hp? I don't think so. Hence, not effective.
The effectiveness of a remote mount turbo sucks. There's no way around it. You will see more gains, and better performance all around the closer you put it to the manifold. Just because I said it wasn't effective does not mean it wouldn't work. It's just not very good at what it does.

They run around 6psi tops, and with a rotary putting out as much exhaust force as they do, seems like it would be more than capable of boosting to 6psi and giving NA guys a little more umph.

that's a false statement if ever there was one
. Look the turbo works off of pressure differential NOT exhaust velocity (I'd be interested on how you know how much Force our exhaust puts out). The pressure differential for the turbo comes heavily based off of Temperature. The farther away you put the turbo from the exhaust ports on the engine the less of a differential you have. This means more spool time is required to make a specific amount of boost.
Bottom line is this: Will it work? Yes. Is it worth the time and money and head ache for it? No.
