Having an increased capacity oil pan for the RB26 is a must for all owners running high flow oil pumps in order to ensure sufficient oil supply under all conditions.
The HPR billet sump extension kit is a complete solution with a well engineered baffle kit and reinforced front diff cover. This together with the modular sump extensions makes it the very best wet sump solution available for the RB26.
Features and benefits
- 50% Increased oil capacity ensures consistent oil supply, even during high-G turns and acceleration
- Billet modular design with removable extensions
- Equal amount of increased capacity on both sides of the sump
- Stock height oil pan, No need for custom oil pickup
- Baffled weld inserts for controlled oil flow
- Reinforced front diff cover
- Reduced installation time
- Less cutting and welding compared to other solutions on the market
RB26 Front diff cover
HPR reinforced front diff cover CNC machined out of 6061 aluminum and anodised.
-The cross sectional area of the cover is doubled in thickness, and the bolt holes are reduced in size to completely eliminate potential movement and cracking of the front diff housing.
The oil filler plug and drain plug has been moved in order to clear our sump extension kit, but can also be used for stock RB26 oil pans.
The cover comes with stainless steel breather cover, viton o-ring, new drain and filler plug, and custom low profile bolts.
RB26 Oil pan baffle kit
The RB26 oil pan baffle kit is developed using full scale CFD with simulations of extreme G-forces found on track. The baffle runs the same height as the OEM baffles and has internal edges to trap the oil into the baffle.
The Z shaped top plate stops the oil from going away from the sump under hard acceleration, and forces it back to the sump where it should be.
The Improved Racing trap doors used in this kit are designed specifically for fluid baffling and are completely maintenance free. They feature a 60 degree stop position and have a lot less resistance to flow versus rubber doors.
Comes with all needed hardware.
