Any progress on this?

Did this ever get completed?

I personally would love to know the progress on this. The stock charger is far from the best I've seen and this could be a very easy way to make much needed improvements.

Is This still happening?

I hope this is still happening.. I'd love to have an upgraded turbo

There most likely is very limited interest, but there is quite a lot of interest as to what could be possible. Updates would be greatly appreciated.
