Causes of low oil pressure, na vs turbo
Got the turbo all installed this past friday and noticed the oil pressure was much lower. Fixed a few leaking items thinking that could be the culprit. However my pressure is still a bit lower driving around turbo vs pre turbo.
I dont have any before pictures but here is now
Oil temp gauge is still not installed although the oil was not super hot, car had been sitting for about a hr before drive.
Before the turbo i would see about 40 psi driving and hwy driving i now see 30 and possibly lower. At idle i would never go below 20 ish and i feel its below that maybe 15?
There is a 5* uphill bend due to a slightly unlevel tap treading in the oil drain line. Could this cause low oil pressure and should i be worried?

Nick, take your bellypan off until the oil leaks are sorted out. Any oil that does leak is going to collect and drip from one place; without that pan you will be able to pinpoint leaks earlier. Going to a heavier-weight oil is a bandaid fix.

Ill take the bellypan off and continue to look for leaks

It's normal. You have added a path of least resistance in parallel with your bearings which is the turbo. So your pressure will drop as the pump hits the relief valve and maintains a particular pressure. You can add a heavier oil or shim the pump for higher pressure but my new built motor with a turbo and oil cooler doesn't seem more than 40psi at redline at the main gallery.
