The R34 engine, officially known as the RB26DETT, is a 2.6-liter twin-turbo inline-six built for the Nissan Skyline GT-R R34. Delivering around 276 horsepower stock and capable of far more with tuning, it’s famous for its robust iron block, DOHC 24-valve design, and near-perfect balance — a true legend in Japanese performance engineering.

Description
The R34 engine, the iconic RB26DETT, sits at the heart of the Nissan Skyline GT-R R34 — a car celebrated for its dominance in motorsport and tuning culture. This 2.6-liter twin-turbo inline-six produces 276 hp and 289 lb-ft of torque in factory trim but easily supports 500+ hp with the right upgrades. Its strong cast-iron block, aluminum head, and six individual throttle bodies deliver precise airflow and durability even under extreme boost.
Designed for the GT-R’s ATTESA AWD system, the RB26DETT is paired with a close-ratio 6-speed Getrag transmission, allowing power to be harnessed efficiently. Enthusiasts prize its tuning potential and longevity, making it one of the most sought-after Japanese engines ever produced.
R34 RB26DETT fitment is unique to the R34 Skyline GT-R. The R34 uses generation-specific engine management electronics, turbocharger configuration, and wiring harness interface that differs from both R32 and R33 applications. Our application review confirms the R34-specific RB26DETT configuration before it ships.
For R34 GT-R owners and serious RB26 builders comparing a used engine, a remanufactured engine, and an OEM engine for the R34 specification, the answer is unambiguous. A used Nissan R34 RB26DETT engine from a verified low-mileage R34 GT-R donor gives you the factory final-specification twin-turbo inline-six as an OEM engine — the R34-specific turbocharger, the factory refined head gasket, the R34 electronics interface — at a price that respects the R34’s status as one of the most valuable Japanese sports cars ever made. No remanufactured engine from an earlier RB26 generation delivers the R34-specific factory identity.
Every used Nissan R34 RB26DETT engine ships with up to a 90-day warranty and arrives within 2 to 5 business days. Installation is not included. RB26/GT-R specialist installation is required. These are genuine Nissan OEM engines, and we stand behind every unit.
