Hi Octane Racing Cast Extended Sump

Modify and & Return Sump Service

Designed off the original Gibson Motorsport-winning GT-Rs, the Hi Octane Racing alloy sheet fabricated sump extension is a must-have for your Nissan GT-R. Proven for tarmac rallies, circuit racing, and drag racing, this upgrade delivers outstanding performance while adding safety with increased oil capacity.

For years, the Achilles heel of the RB26 engine has been its oiling system, often leading to catastrophic failures under high-performance conditions. The standard RB26 sump barely supports engines producing 206kw under road conditions. Once power levels rise, G-forces increase, and sustained high RPM racing causes the standard sump to run low on oil, splashing it away from the pickup and leading to engine failure. Designed from Gibson Motorsport's Winfield GT-R and tested with success on the Hi Octane Racing R32 GT-R, this extension ensures reliability for circuit racing, drag racing, and road use.

Features of Hi Octane Racing Cast Sump Extension:

• Proven results in tarmac rallies, circuit racing, and drag racing.
• Inspired by Gibson Motorsport-winning GT-Rs.
• Increased oil capacity for safety and reliability.
• Suitable for road use and lowered vehicles.

In addition to our sump extension services, we offer a range of options to enhance your GT-R’s performance. These include a genuine front diff and bearing rebuild kit for refreshing worn components, a vapour blasting service for a pristine, professional finish, and the Quaife ATB Helical Front LSD available for supply but not fitted.

Order Instructions:

When ordering, you'll need to send us a standard RB26 sump with the diff removed and a stock RB26 pickup. We'll modify and fit our cast extension to your sump. Please note, this item does not include a core sump—it covers the cast extension and labor only.

Fabricated parts are made to order and follow a manufacturing queue. For the latest ETA, contact us directly.
