In addition to the pump sucking up all the oil, there are several modifications that the Rb's need that's pretty much a rule of thumb when building an RB's lubrication system there's plenty of info on that stuff on the syline forums.

RB Oil pump tech:
The only thing different on a N1 pump is it has a stiffer spring...

the ebay listed n1 pump has a stiffer spring. its a high pressure pump.

the real N1 1000.00 pump is made of stronger materials..

[Blackzenki82]

no, there's the N1 pump, which is like a OEM upgrade for what $3-$400?

then there's the NISMO pump, which is a $1000, and yeah, it's stronger, and is prob one of the best options.

i didn't say anything about eBay listings... these are OEM/Nismo parts, not garbage.

Tomei has a similar pump at $1000. I'm pretty sure that internal gears (that pump the oil) are wider, as they're listed as high volume, which implies that they changed the geometry.

ebay "n1" pump

Nissan N1 Oil Pump RB20 RB25 RB26 Skyline GTR Upgrade | eBay

oem pump

Nissan OEM Oil Pump RB20 RB25 RB26 Skyline GTR | eBay

the real n1 pump is made by nismo and cost upwards of 1000.00

the "n1" pump has a higher psi relief spring in it, thats it!

yes the tomei oil pumps kick ass! they have a non oem style housing (larger ports, wider gears) better overall design

oil galley reducer from tomei

oil return off the rear of the head to the pan, (just did this to my 26)

open the return ports on the back of the rb head and on the rear of the block (just did to my 26)

Had my Pressure relief valve blow out on my 300zx.

Very very similar to the 240sx.
Might even be the same part to replace it. Maybe.
