I searched and couldn't find the answer. The FSM doesn't state a difference in oil pumps between the two motors so what is it. The have the same specs for oil pressure. Is it really necessary for revving to 72-7500 rpm?

Thanks

 

The rev up pump doesnt necessarily flow anymore volume of oil, but it was designed for higher RPM operation. It's cheap insurance when building an engine.

 

+1 what Sharif said.

 

Do you run any risk by revving into the 7's without it? It's alot of labor time if your not doing anything else to the engine.

 

I wouldnt change out the pump, unless you are planning to build your engine.

Unfortunately, your question cannot be answered 100%...we would just be guessing.

 

I'll have to see if I can find some one in corporate to tell me the differences.

 

Like i said over on maxima.org, the standard oil pump is good for at least 7500 RPM.

 

Well excuse me for asking 350z owners I just want to be double sure. When I swap internals I'll swap it out, but until then I don't want to kill her.

 

I would venture to say no. OPs have changed little, in all engines in the last 40 years. Up Grades are generally Higher Volumn or Higher Pressure. I would say that they may have gone with a Higher Volumn Pump, Higher Pressure would be of little use and never has been the way to go.

If they are interchangable, do it if you build the motor, but I just cant see doing it as a single mod

Disclaimer: IMO

 

I might add---- and am ready for a rant, But the bottom line is, an engine is an engine and the same basic rules apply in most cases

 

Is there any where else to get one than from the Stealership?
