oil drain

[guism]

hi there,
Has anybody use the old supercharger oil drain for the turbo oil drain instead of open a new hole in the lump?

The drain on the turbo has to be much bigger than the supply - hence welding a new boss in the sump. If you use the OE supercharger drain you could end up with a head of oil in the turbo. It'll leak past the seals and smoke like a chimney.

Long story short, it's been tried but it's not big enough.
