92BOOSTED

Unless you are putting the turbo above the valve cover and it is sticking out of the hood,you would need a scavaging pump for the oil so it forces the oil into the valve cover.The oil return on the turbo is only gravity feed and it needs to be on a downward angle going to the oil pan(no upward curves) or the oil will get caught in the return line and wont drain.This will cause the oil to stay in the turbo (bad) and when it gets hot enough(oil) the viscosity will break down and you will lose your turbo.
And you dont have to drill if you dont want to.You can punch a hole in your pan(carefull not to hit your crank or mains)and weld your bung in place,that way there is no metal shavings,and it wont leak.
You will have enough oil pressure for both the turbos and the engine.Do you have the hi volume pump?
