The factory oil supply to the turbocharger is too much for the pump, but by design, the 3LDZ and K2x-series turbochargers act as an oil flow restrictor -- so what drains from these turbochargers ends up being a good amount less than the pump's capacity.

In contrast, a plain journal bearing T04/T3 turbocharger uses a full flow bearing design, so "too much" oil drains out of the turbocharger into the oil drain canister, more than the scavenge pump can keep up with. That's why those turbos require a larger scavenge pump.
