After Paul suggested the second pipe for the turbo waste gate, I opened my
newly rebuilt turbo. Together with an old machinist we decided that it is
very doable. Right now the waste gate is opening maybe only 3/16" or even
less. If an opening of about 2" diameter is made on the cover for a pipe,
the waste gate will open much more. The machinist said the cover plate is
forged steel and will weld very well.
The advantage as I see it, will be less stress on the turbo, comparing to
over speeding the turbo and dumping the access air out.
I have a lever on my quadrant just for the waste gate.

Bulent, make something like this more or less and you can open
the waste gate valves 90 degrees. That will allow a die grinder in
there to port the waste gate passages. This can be flame cut or laser
cut out of steel.
