What power do i need a better oil pump for rb26???

[RB26VL]

hey guys i got a rb26 with 350rwhp (in 2wd in a vl) atm on 17psi, with bigger inj, highflow turbos, pods, zorst, etc and i am getting the 4wd gtr sump enlarged and baffled as we speak and i was wondering what sort of power figures do i require a better oil pump?

whats the n1 pump good upto?

is it worth getting the n1 pump or another jap brand for the extra $$$???

im using the car mainly for street use and the occasional track day or drag meet if thats any relevance

cheers

ur stock oil pump will be fine for the power u have but i guess once u start making 300rwkw then oil pump should be considered, I would spend the extra money on an oil cooler, benifits from that are more than u know, i guess its not a matter of what hp is the various oil pumps limited to its more the point of how much u want to help ur engine?

does anyone know where you pick up and return the oil in an engine oil cooler?

N1 is fine for huge power but not revs so stay around 8300rpm max.

ahh the revs thing i was unaware of, nice to know. I got a max revlimit of 8k on mine in future anyhow. Thanx for info steve

they usually have an addition that comes from the oil filter location, just a supply hose to the cooler and a return hose back to the fitting. although no doubt it can be done differently.

as covered many many times the n1 pump is the same as the normal pump with a higher spring rate so it runs slightly higher pressure, you can do this to your standard pump for $20. Also if you are running an early r32 engine it would be wise to invest in a r33 on pump and a jun crank collar to address drive engagement issues the earlier designed cranks have!!!

where exactly can you get the n1 pump, over here in the states its nearly impossible to track one down.

im ordering one from greenline for AU$376.i also need the collar to fit it to my rb30 crank.

does anybody know where to get the collar?

[Fitzpatrick Speed Works]

greenline should have them for around 220, but if that fails try croydons they sell them for 260.!!!

[dnb]

well greenline dont know what im talking about!.

looks like ill have to go croydens.

this collar is almost as dear as my bloody pump!

Only 1k+ for new RB26 crank

so the N1 pump and the nismo high volume pump sold by nengun for about 1k are not the same aahhhh that makes sinces.So at wot level rwhp do you need to go to high volume pump ie tomei, jun, etc etc as i am running about 390rwkw and are about to upgrade internals and pump etc

Mickinney usally has some try them

[carl h]

while mckinney may have them they will also bend you over and ream you in the arse in terms of price.

they are trying to sell the n1 water pump for nearly 300$ usd, thats a bit much!

[Grinch]

I said they have them never said it was a good price

anyone know the limits of the rb25 pump? can i change the relief valve spring to raise the pressure a little more for higher revs?
