N1 Oil Pump Flow More Than Factory?

[maximajim]

Been reading for years that the N1 pump just has a higher rated spring over the standard pump

I just read this

www.gtr.co.uk/forum/upload/39978-n1-oil-punp-upgrade.html+N1+oil+pump&hl=en&ct=clnk&cd=5&gl=us

is this true? Or did this person pick up a Nismo pump rather an N1?

thanks!

Didnt read the link, but the n1 pumps definately flow more than gtr ones.

n1 oil pump pumps around 25% more oil than standard. theyre a high flowing oil pump.

if you're using one on a high revving engine make sure you do the oil feed mod to your block as it can empty your entire sump 25% quicker

high pressure pumps increase oil pressure throughout the rev range.

you can make any oil pump have a harder spring, just tighten the big bolt on it. all this does is raises or lowers the peak oil pressure.

it works on the same principal a wastegate works on.

What is that mod?

Is it applicable to the RB25DET?

I was under the impression N1 oil pumps flow "LESS" than factory ones.

they are designed for constant hi revs.

and being that the RB's all have oil control problems, where by too much oil gets pushed to the head, the N1 designed for that sort of situation flows LESS.

Same goes for the N1 water pumps compared to other RB water pumps.

thats true but only for the N1 water pumps. they flow less at low rpm because they were designed mainly for vehicles that are track dedicated or vehicles that are driven hard (sustain high revs, often) and are fed a higher volume of water at higher rpm where they spend most of their time.

N1 oil pumps flow more all over the rev range. they are a 'high volume' pump which means more oil and higher pressures. i've got one in my car and my std gauge reads a little higher than what it used to before the build.

Well the thing is I've always *read* the n1 pump just has a higher rated spring. I've never came across something otherwise until recently. Even sydneykid said so himself

Higher pressure doesn't substaniated higher volume. You can have higher pressure with the same volume.

they're actually advertised as N1 High Volume Pumps.
