N1 Oil Pump with Billet 4340 Gears
N1 Nissan oil pump housing, OEM spring and relief valve with Billet 4340 Gears
77mm diameter outer gear / 10.96mm thickness.
This set replaces the standard N1, RB25 NEO and OEM GTR gears which are powdered metal.
Now with Isotropic Micro Finish.
Precision machined from 4340 billet steel, featuring an N1 spec 'wave' profile for higher flow. These gears have been proven under extremely harsh conditions & stress.
Spline driven gears are a much better, positive drive and more effective way to drive the Nissan oil pump.
This type of setup is used in all OEM Toyota 1JZ and 2JZ oil pumps ( See pics below ) and numerous other OEM engines. There is no "chatter" or "back lash" which is common with the OEM RB drive setup.
