The turbo survives with surprisingly low oil pressure and flow. It is virtually certain that all engines in production today have enough excess oil-pumping capacity to adequately take on the additional requirement of lubricating the turbo. If you know a particular engine was shortchanged in the oiling area on original design, it is certainly a good idea to fix it. However, fix it for the en¬gine's sake and not for the additional burden of the turbo. Observe the basic lower limits of oil pressure and flow published by the turbo manufacturer and you can't go wrong as far as lubrication is concerned.
Too much oil pressure can create problems with turbos. It is possible to force oil past oil seals that are in perfect condition if oil pressure exceeds 65 to 70 psi at the turbo. If a particular engine creates more oil pressure than the seals can handle, it may be necessary to install a restrictor or bypass system to reduce pressure at the turbo.
Problems of oil pressure overpowering the seal are evident in a frequent if not quite constant smoking problem. Anytime oil pressure exceeds the 65-70 psi range and smoking persists, a restrictor or bypass should be installed prior to any other changes.

Turbo tech has certainly changed a lot since this was authored, so be sure to check in with aftermarket manufacturers. Anything MHI should not be fed direct from OFH.
