I have an OEM Borgwarner K03 turbocharger from a EA113 engine selling for $5K.
There is nothing wrong with the unit. The unit never smoked, had any oil leaks, or had any shaft play.
I had upgraded to a larger turbocharger, so I had this in storage. I've placed a 5K YouTube video of the actual unit for you to see.
I'm sure many of you have fabricators that can cut and weld the manifold or flange to fit your existing one.
