Hy guys, i've found a nismo oil pump a resonable price(RHD ) so my question is:
why the official tuner of nissan produce a oil pump more cheap than other tuners?

Is a good pump or only re-branded nissan pump?
difference between usual tomei or jun oil pump?

Nismo pump is basically a stock pump with Reimax gears.
Tomei pump is absolutely different design and significantly more flow.

If you can stretch, then go for the tomei pump with an extended sump.

That is a a very expensive option because with a tomei pump you need an extended sump. Still does not address the flat drive with the potential to break the drive gear.

my old engine had jun pump and extended sump has done 20 - 30k miles and still going strong with an 8700 rpm limit on stock balanced crank
