My DeLorean tends to start quickly and with gusto. This means that the turbo is expected to spin prior to engine oil pressure having a chance to develope and transfer out to the turbo. There isn't really much that can be done about it except to make things as short coupled to the source as possible. Filtration could definitly introduce delay. One good policy however is to provide a droop in the pressure line near the turbo. When the line drains at engine shutdown hopefully this depression can provide an immediate burst of oil to get the turbo thru until the main supply is up and flowing. Try to plumb it such that this supply line does not drain when the engine is not running. Prolon oil additive is also an excellent product to help extend the bushing life of turbochargers.
