oil drain and oil supply
 

anyone with a turbo or supercharger where do you tap into for the oil supply and oil drain.

Depends on motor- if its an LT1 it depends on the years- early ones there is a 1/2" NPT above where the oil filter is-

The drain you have to punch and tap the pan...

it's a 99 3.8l v6

Well in that case I'm not sure- look for a fitting on the block around where the oil filter is- if you can't find one try a google search to figure out where other people have tapped into to get oil.
