RB26 sump extension  kit

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.


Included in the kit

  • 2x Billet sump extensions
  • 2x Baffled weld in flanges
  • Support flange with high tensile bolts
  • Cutting templates
  • Oil pan baffle kit
  • RB26 Front diff cover kit
  • Viton o-rings 
  • Filler/drain plug and all needed hardware included


Optional

Oil-temp/pressure combination sensor
Genuine Bosch motorsport sensor supplied with connector/pins and dowty seal.

Mixes my protein shake powder
Color: Blue
My husband and I both drink protein shakes daily. We have vortex mixers that work great, but they are plastic and getting old, and really needed to be replaced. In an effort to reduce microplastics in our lives, I am trying to use less plastic mixing cups. I couldn't find anything small enough (other than regular blenders) with glass and metal parts that would work well for us. During my search on here, several frothers showed up. This one caught my eye because of the amount of sales, quick delivery, and of course, decent pricing. Some of the reviews had me a little skeptical, and time will tell regarding the longevity, but so far I am pleased. My protein powders are on the heavy side, but this little frother really gets the job done. Instead of having to use separate mixing cups (saving me on dishwashing), I just use my morning coffee cup (it's big enough) to mix my protein shake in. My husband just uses a regular glass. Neither of us can believe the power this little thing has. We are getting smooth shakes! Here is what I really like about it: It is powerful and mixes well; the frother is metal and not plastic; it cleans extremely easy; after making several shakes the battery has not died; can be used in glasses, coffee cups, even disposable cups (when we buy donut shop coffee); and I love the little stand which takes up barely any counter space. Less plastic, less clean-up, dependable (so far), and small, making it convenient even for travel. I'm really glad I got this, and hope it will last. One last thing, do not turn it on while cleaning under running water. (Yes, you can laugh.)

Powerful frother with a long rechargeable battery life
Color: Black
After purchasing three of the battery operated frothers. I finally found this amazing frother. It is very powerful so you do have to be careful not to slosh liquid out of your cup when you’re using it. But I have found it helps if you rotate the frother in a stirring motion while you are using it. That really helps keep the liquid from overflowing out of the cup. It has a sleek design and is rechargeable and the charge less about two weeks.I love this one so much. I take it with me when I travel. I actually left my original one at my mother’s house the last time I visited her and have ordered another one for my house. Highly recommend.

Great Power and Creamy Foam
Color: White
This frother is amazing and has really good power. It creates creamy, smooth foam in seconds and works perfectly for iced lattes, cappuccinos, and matcha. I love that it’s rechargeable and lightweight, but still feels strong and high quality. As someone who loves coffee, this has become one of my favorite tools for making café-style drinks at home. Easy to use, easy to clean, and looks beautiful on my coffee station.

Powerful easy to operate but splashes
Color: Black
Excellent frother--Very powerful and easy to turn on/off with one button. The only downside is it requires a deep container in which to froth. The frothing pitcher I had was too small and milk splashes everywhere. There is no lower speed so it works fast. I am using a deep insulated container now for frothing. Otherwise, very quite, easy to operate no pushing down on the top like other frother wands. I love it as long as I can control it to limit the splashing.

Froths Milk in Seconds
Color: Black
Frother I had for a couple of years broke. Based on reviews I bought this. Love it being rechargable. The POWER! It froths milk in seconds. Also great for that after workout protein drink. Also is a little longer than my last frother so it works great with larger glasses.
