The RB26DETT engine is known to have a few oiling issues that have been addressed and addressed by enthusiasts and tuners over the years.

1. Oil Pump Failure: One of the primary oiling issues with the RB26DETT is related to the oil pump’s durability. The stock oil pump can struggle to handle increased power and higher RPMs, leading to insufficient oil pressure. And we all know this isn’t good…
   Upgrading to a higher-performance aftermarket oil pump is in my future, if anyone from Nitto is listening?
2. Oil Surge: Another issue that RB26 faces, particularly during aggressive cornering or high-speed driving, is oil surge. Occuring when the engine’s oil supply cannot keep up with the lateral or longitudinal forces generated by the vehicle’s movement. This can lead to oil starvation in critical engine components, potentially causing engine damage. Baffled oil pans, oil catch cans, and oil pan modifications are commonly employed to mitigate oil surge and ensure consistent oil supply.
3. Cylinder Head Oiling: The RB26 engine has a design where the cylinder head is supplied oil from the front of the engine. This configuration can cause unequal oil distribution between the front and rear cylinders, leading to potential oil starvation in the rear cylinders. Engine builders and tuners often address this issue by modifying the oiling system or adding additional oil galleries to ensure proper oil flow and lubrication to all cylinders.

It’s important to note that these oiling issues are more prevalent in high-performance or heavily modified RB26 engines – and where I’m going we all know that this will affect me. With proper maintenance, regular oil changes, and aftermarket upgrades, many of these issues can be mitigated, allowing RB26 to handle higher power levels reliably.

The aftermarket solutions, such as improved oil pumps, baffled oil pans, and oil system modifications, really do help address these oiling concerns and enhance the engine’s performance and longevity. Thankfully.

If you’re hungry for more power, consider swapping to bigger twin turbos. Imagine strapping on a pair of turbos with larger compressor wheels that deliver a massive surge of boost. The result? Mind-blowing power and acceleration that will leave you grinning from ear to ear. Don’t forget to upgrade your fuel system and engine management to handle the added horsepower.

But wait, there’s more! How about a single turbo conversion? By replacing the twin turbos with a larger single turbo, you’ll unlock even more power and torque. The distinctive sound of a single turbo spooling up will send chills down your spine as you unleash the beast on the road. Get ready for an unforgettable adrenaline rush like no other! Especially if you went for the T51R mod…

Of course, with great power comes great responsibility. Upgrading your turbo setup isn’t just about adding more horsepower; it’s about controlling that power effectively. That’s where a high-quality boost controller comes in. It allows you to adjust and fine-tune the boost pressure, optimizing performance for different driving conditions. With precise control over your turbo’s boost, you can ensure the power is delivered exactly when and where you want it. Ideally, you want to be controlling the boost with your ECU, rather than having two systems working independtly of each other. That never works as well.

Now, let’s talk supporting mods. Upgrading your fuel injectors, fuel pump, and intercooler is crucial to maintain the right fuel-to-air ratio and prevent any power-hungry issues. A high-flow exhaust system will let that RB26 roar, while a reliable engine management system keeps everything running smoothly.

Embarking on a turbo upgrade journey opens up a world of automotive excitement. It’s a chance to unlock the true potential of your RB26DETT engine, taking your GT-R from great to awe-inspiring. Each turbo upgrade brings a new level of power and performance, ensuring that the thrill never ends as you push the limits of speed and acceleration.

So, if you’re ready to embrace the excitement and unleash your inner speed demon, why not upgrade those turbos? Turbo madness awaits you, and the thrill of the open road has never been more enticing! Get ready to experience the power, the speed, and the pure joy of turbocharged performance. Your RB26DETT and your heart will thank you for it!
