N1 vs. Stock oil pump (pressure difference)
N1 vs. Stock oil pump (pressure difference)
Does anyone shim or replace the stock oil pump spring for more pressure? Why does everyone rush out and put in a N1 pump? If you have a accurate gage and could post up some numbers at say idle and then at 3-4 thousand rpm--- I would like to see the differences in the two pumps in action. My pump is in spec and I would like to know of any benefit to shelling out $$$ for a N1
Re: N1 vs. Stock oil pump (rotorimp)
The last time my car ran it was 100psi at start up idle, onece it warmed up it would go down to about 30psi, and at 3000-4000 rpm it would go to 75psi and stay there till redline. I hate to say it but, search. There was a really good thread about this a while ago. The inside of the pumps are different.

BTW--jdmser are you running the N1? What weight oil are you using?

Re: N1 vs. Stock oil pump (rotorimp)
I'm running the n1 oil pump with Mobile1 15w50 in a RB20. My stock pump started to slip after some highway pull so I did the crank collar and pump all at once. I'll never put another car together without an oil pressure gauge. Saved me a butt load of money this time around.

Yep-the Oil pressure is going right next to the wideband and the temp. gage.
URAS--much appreciated--that is what I was looking for

the hks/greddy/jun/tomei pumps are quite nice but for the price...well unless the car sees high revs constant the n1 is a good alternative.if i were to upgrade from the n1 to a japanese pump i would go for the nismo, biggest gearset of them all and damn near indestructible.1k price tag hurts to look at tho.
on my n1 pump i get 6bar at start up, 2 bar at idle when warm using 20w50 oil.then from 3k to redline its a solid 6 bar.oil pressure is key especialy on high rev motors but remember pressure != flow.
just because a pump can move more oil doesnt mean its better, the more oil it can move the faster the pan goes dry, so if you are dead set on a large upgraded pump be sure that you have added external drains/restrictors and if possible increaced capacity pan.

Thanks for the reply--I want to put the $ where it will do the most good. I am pretty sure that I have the cooling system in check and am going to hold off on the oil pump/oil modifications till I build the motor. I have been doing allot of research on motor oiling. I shimmed the stock pump and will compare the specs. to what people have posted and the research I have done/found on other web sites. I will post up what I find.
