Oil Pump

[Noddy]

Im about to do a rebuild on my RB25 which I have been using for sprints and mostly drifing.

I want to upgrade the oil pump and was concidering an N1 Nismo pump.

I can order it through a mate who runs the spare parts section at my local Nissan dealer if I can give him the part number.

Am I doing the right thing?

Can anyone tell me the part No?

What would you use?

is the rb25 oil pump the same as the 26??

do oil pumps exchange between engines?

I will be interested in the response to this question as I seem to recall reading somewhere that the water pump and oil pump are inter-changeable but I can't locate wherever it is that I read it.

Cheers

N1 pump fits.

My RB25 has a N1 oil pump.

I have yet to find an RB water pump or oil pump that doesn't fit all RB's (RB20/25/26/30).

In my opinion N1 pumps are a waste of money, they have no more flow than a standard pump. Just a stronger spring in the pressure relief valve. Save yourself ~$300 and buy a $2 spring upgrade for your standard pump, same result.

Thats what ive heard, a "Genuine" N1 RACING oil pump is priced at $5000 approx, what we all class as a N1 oil pump is a normal pump with a heavier spring and valve,, thats about it.

Just for the record the N1 pump and the NISMO pump are two totally different oil pumps and about $600.00 price difference. The nismo been the better one.

What's a worthy upgrade for an early RB26 in terms of new oil pump?

I'd heard that the R33 N1 was the go due to it 'catching' on the crank better?

Ya prolly getting confused between the cranks of the R32 and R33 GTRs. The R33 crank end extends further and engages into the oil pump socket better. This can be rectified on the R32s by adding an extension adaptor (fairly easy to machine up).

Not sure on the part number but go on greenline.jp or nengun.com for the nismo pump.
