Brand: Tomei
Product: Oil Gallery Orifice RB26 RB25 RB20
Part Num: 191071

FEATURES:
The Orifice controls the amount of oil flow that is delivered to the head to lubricate the parts in the cylinder head and to cool down the engine assembly. However the stock oil-gallery orifice has a hole that is too large which allows too much oil to be delivered to the cylinder head which will cause the problems as listed below:
1- Too much blow-by Gas
2- Blowing engine oil
3- Leaking oil through the valve guides
4- Insufficient oil delivery to the crank journal
5- Allows air pockets into the system from when the oil pan is under horizontal G-Forces

The Tomei oil gallery orifice was designed from the experience and data we had obtained from the development of Tomei N1 endurance and drag racing engines. By restricting the diameter of the orifice to 1.5mm (Normal is 2.0mm) Tomei succeeded in securing enough lubrication to the camshaft and valve while maintaining the correct amount of oil in the oil pan which resolved the common problems.

SPECIFICATIONS:
Diameter: 1.5mm (OEM 2.0mm)

PRODUCT NOTES:
- Combine with STD orifice to use- For added Blow by prevention, Tomei recommend using the Tomei 3D Profile pistons.

COMPATIBILITY NOTES:
- RB20, RB25: Solid type engines ONLY (not to be used on lash type RB20 & RB25 engines)
