Oil Gallery Orifice for 1989-2002 Nissan GT-R by Tomei
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.
Features
- Restricts diameter of orifice to φ1.5mm
Benefits
- Maintains the correct amount of oil in the oil pan which resolves the common problems with the RB26DETT
