what to expect for oil press gauge to read?
 
I just put my oil press gauge on, and am putting my turbo n right now, what should it read when all is done?

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.

Ok well my gauge when my oil is FULLY warm and car is at temp is about 20+psi at idle and about 85+ at say 5000rpm.

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..
