Nitto Billet Externally Adjustable Oil Pump - Nissan RB25DET / RB26DETT / RB30 - Skyline / Skyline GT-R (R31–R34) / Stagea (WC34) / Commodore (VL)
An externally adjustable oil pump for Nissan RB engines, machined from 7075 billet aluminium and hand assembled and tested by Nitto. It is built for high-power street, drag and circuit RBs where oil pressure and pump reliability matter most.
This pump is Sine Drive only and must be used with the Nitto Sine Drive crank collar (sold separately). It can be fed from the factory internal pickup, an external -10AN feed, or both at once.
Note: Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
Features
- Housing and backing plate machined from 7075 billet aluminium
- EN26 billet steel gears
- Externally adjustable oil pressure
- Revised internal galleries with tighter clearances for higher pressure
- Optional -10AN external pickup feed, with or without the internal feed
- Hand assembled and tested in house by Nitto
- Supplied with gasket and front seal
