RB25 Oil Pressure

[xcye]

If the pressure you are seeing now is consistently less than 70psi and your current stock pump is not worn out, then a N1 pump won't remedy anything. An aftermarket pump with larger volume is the only way to go with larger than stock bearing clearance setup.

The clearances are larger than stock so the motor doesnt wear its self to bits within a year. There are quite alot of modifactions done to my set up, it only puts down stockish numbers due to the size of the turbo currently on it. GT2535r. I'm going to trust my engine rebuilder of most people concerning what i should use for oil. Anyways.. i found a N1 oil pump in town i will be picking up before the weekend, then ill pull the motor and swap pumps and have her sealed up by sunday again if all goes well.

15w50 was good in my car
Running 15w40 this year and it's the same if not better
My oil pressure is aroud 40-50 under load and my recent compression test showed 165-170psi across the board.
These motors have individual attitude lol

I installed the N1, oil pressure is now 40 psi at idle and 90 at full boost.
