Check the 3rd post down... 
Oil flow and pressure requirments
The turbo survives with surprisingly low oil pressure and flow. Is is virtually certain that all engines in production have enough excess oil pumping capacity to adequately take on the additional load of a turbo.
To much oil pressure can creae problems with turbos. It is possible to force oil past the seals that are in perfect condition if oil pressure exceed 65-70psi at the turbo. If your engine has these high of oil pressures a bypass or a restrictor (needle valve) can be used.
Problems of oil pressure over powering the seals are evident in a frequent smoking problem.. anytime oil exceeds the 65-70psi and smoking arises put a needle valve or bypass in.

im not talking ---- by any means, but your essentially saying DSM's have built in restrictors? My DSM, on cold startups, would get up to 120psi oil pressure. And thats not uncommon..
