I got an email with a quote on some other items but had asked about the kit. He said that it would be available something like mid December (I think, I was also looking for a couple of other parts and it seems like it was mid Dec or mid Nov).
It was supposed to be able to work with existing BiTurbo's, the ones that are made for stock Tomos. I am not sure about the ones for Puch.
If you email him, he responds pretty quick!!
