Designed off the original Gibson Motorsport winning GT-R's, the Hi Octane Racing cast alloy sump extenion is a must have for your GT-R!

For many years the oiling system has been the achilles heel of the RB26 engine causing many catastrophic engine failures often the first time the vehicle ventures anywhere near a racetrack. The standard RB26 sump is barely adequate for an engine producing 206kw under road conditions. Once this horsepower is increased so too are the G forces and once this is coupled with sustained high RPM experienced under race conditions the standard sump will run low on oil and what little oil is in the sump will be splashed away from the pickup which usually results in engine failure. We have been manufacturing fabricated sumps for quite some time but these are both expensive and time consuming to manufacture, so we have introduced these cost effective cast versions.

This was originally designed off the Gibson Motorsport Winfield winning GT-R's and was also used on the Hi Octane Racing R32 GT-R for tarmac rallies, circuit racing & drag racing for many years.

The Hi Octane Racing sump extension does not hang as low as other competing products so it is excellent for lowered cars.

Note: When ordering this we require you to send us a standard RB26 sump with the diff removed along with a stock RB26 pickup for us to modify and fit out cast extension to. This item does NOT include a core sump, this charge is for our extension and labour to fit only.

Sumps are made to order, we try to have them manufactured approx 1 week from order however depending on workload at the time of order please allow 1-3 weeks, if you require the sump urgently please contact us to confirm current ETA before placing your order.
