i just got an rb26 running in a friends car and the oil pressure is reading 2bar all the time .. at idle and all rpms. I'm not sure what the factory oil pressure is, but that seems a bit low for a nissan motor. ... anyone have any ideas?

at 900rpm I had around 2-2.5 bar (depending on last oil change) I would get up to 4-7 or 8 bar. Only 2 bar (29psi) through all RPM's does not sound good. Something is not right.
