Nissan OEM Oil Pump RB26 RB25 (also for RB20 RB30 and NEO)
The Nissan OEM Oil Pump for the RB engine series is a direct replacement for both short and long collar crankshafts. These pumps are brand new from Nissan offering you the assurance of a factory replacement part. Included on the pump is the front main seal. You'll want to consider the oil pump gasket and oil pump bolt kit as well when installing.
If wanting a slightly better pump to upgrade to, you may consider the Nissan N1 Oil Pump.
