Rb26/30 Sump Modification

[NissanFreak]

If i end up keeping my running gear i will enlarge and improve the sump oil capacity and anti-surge characteristics. The 4WD sump has already been installed with a boxed pickup at the bottom, which then taps into the RB30 block from the outside where the old oil-pickup used to be, this is due to the sump blocking the RB30 oil pickup. The engine is going into an R32 GTR and i want to know what i can do do improve on this. I already have an oil cooler so the oil capacity will be slightly increased but im sure other things can be done aswell

Thanks for your help

Anyone got any ideas or recommendations? Ive also added the drain back the rear of the head back to the sump

What are your intended uses for this car? Road, Circuit, Drag, Show, Drift etc

cheers

Road and maybe drag

so if your prodominately using it for road what is wrong with your current setup..?

[NissanFreak]

Nothing that i know of, i just want to make sure that i dont damage the bottom end due to a oil starvation/surge.

I am told it will make over 400awkw on pump so i want to make sure it safe

You won't generate enough G-forces on the road to need anything better than what you have. If you are running water cooled turbo/turbos, an oil cooler is probably not necessary either.

If you are intending to use road tyres for the drags you won't need anything better than a standard sump. For radial drag tyres or slicks the most common sump upgrade we see is the Trust sump extension. This solution would mean redoing the external feed to the pickup.

Thought you were selling the GTR?

400awkw ? man you should be abusing this thing at the track when its done, would you even be able to put that down without slicks?

I was doing some surfing around the net and came across this on the high energy website. The sump looks good, still plenty of ground clearance but some extra volume plus trapdoors. It might be worth a look http://www.highenergy.com.au

BUSTER: Havent had anyone actually buy it yet so until someone does il keep moving forward.

ProEngines: I just rang Hi-Energy and they said that the sump in your picture was a one off for the owners car and due to "poor casting" that they will not be making anymore.

Maybe Hi-Energy know something all the jap tuning shops dont? I doubt it but thats what they said anyway

Rather than a 'poor casting' it's more likely they had trouble cleaning it or simply didn't clean it properly, which is essential for TIG welding (and to be fair not that simple on a cast alloy sump that's contained oil for many,many years).

acid clean and abrasive blasting should clean it like new

Well im not sure, but it looks like i will keep the setup i have for now
