i think its best to go to www.gtr.co.uk (http://www.gtr.co.uk) it has a lot of information there and a forum, with more skyline owners than here,so they can help you out

1) Don't believe the factory gauge.
2) It's normal for the pressure to drop. Once it doesn't drop too far. Mine has been down to virtually zero on the gauge, but that was due to severe overheating caused by a blown head gasket. Now mine starts out at 4 when cold and when warm will drop to around 2 at idle, maybe less (on the factory gauge). Best thing - if it bothers you, fit another gauge and verify it actually drops.

Would post a pic of the oil pump setup but this forum doesn't support. But the pressure regulator is in the pump.
