The Legendary Nissan Skyline GT-R Engine: A Deep Dive

The Nissan Skyline GT-R is one of the most revered sports cars in automotive history. Known for its cutting-edge technology, exceptional performance, and iconic design, the GT-R has captured the hearts of car enthusiasts worldwide. One of the primary reasons for its legendary status is its high-performance engine. In this article, we will take an in-depth look at the engines that powered the Nissan Skyline GT-R over the years, focusing on their specifications, innovations, and impact on the automotive industry.

The Evolution of Nissan Skyline GT-R Engines

Nissan Skyline GT-R (1969–1973) – The Beginning

The first-generation Nissan Skyline GT-R (Hakosuka) was introduced in 1969 and was powered by the S20 engine. This was a 2.0-liter inline-six engine featuring DOHC (Dual Overhead Camshaft) technology and a high-revving nature.

Engine Specifications:

• Engine Code: S20
• Displacement: 1,998 cc
• Configuration: Inline-six (I6)
• Power Output: 160 hp @ 7,000 rpm
• Torque: 177 Nm @ 5,600 rpm

This engine was derived from the Prince R380 race car, giving the first GT-R a competitive edge in motorsports.

Nissan Skyline GT-R R32 (1989–1994) – The Birth of the RB26DETT

After a 16-year hiatus, Nissan revived the GT-R nameplate with the R32 in 1989. It featured the now-iconic RB26DETT engine, a 2.6-liter twin-turbo inline-six that would define the GT-R’s reputation as a high-performance beast.

Engine Specifications:

• Engine Code: RB26DETT
• Displacement: 2,568 cc
• Configuration: Inline-six (I6) twin-turbocharged
• Power Output: 276 hp @ 6,800 rpm (officially, but closer to 300 hp in reality)
• Torque: 353 Nm @ 4,400 rpm

The RB26DETT was paired with Nissan’s ATTESA E-TS all-wheel-drive system and the Super-HICAS four-wheel steering system, making the R32 a formidable competitor on both road and track. It earned the nickname “Godzilla” for its dominance in motorsports.

Nissan Skyline GT-R R33 (1995–1998) – Refining Performance

The R33 GT-R retained the RB26DETT engine but featured refinements in aerodynamics, chassis rigidity, and drivetrain improvements. While the power figures remained the same, the R33 was more stable at high speeds and had improved handling characteristics.

Nissan Skyline GT-R R34 (1999–2002) – The Pinnacle of RB26DETT

The R34 GT-R is widely regarded as the pinnacle of the Skyline GT-R lineage before the introduction of the R35 GT-R. It featured the final iteration of the RB26DETT, with improved internals, better cooling, and enhanced tuning potential.

Key Upgrades:

• Revised turbochargers with ceramic exhaust wheels
• Improved oil and cooling systems
• Enhanced ECU for better performance tuning

The R34’s RB26DETT was highly tunable, with aftermarket modifications pushing it beyond 1,000 hp in extreme builds.

Why the RB26DETT Became Legendary

The RB26DETT engine is regarded as one of the greatest performance engines of all time. Here’s why:

1. Strong Engine Block – The iron block construction allowed for high boost pressures without compromising reliability.
2. High Revving Capability – The RB26DETT could rev to 8,000 rpm, making it ideal for high-speed performance.
3. Parallel Twin-Turbo System – The dual turbochargers minimized lag and provided a linear power curve.
4. Advanced Technology – Features like individual throttle bodies and a well-designed intake manifold optimized airflow for maximum efficiency.
5. Tuning Potential – With the right modifications, the RB26DETT could achieve astronomical power figures, making it a favorite among tuners.

The Successor: Nissan GT-R R35’s VR38DETT

With the introduction of the R35 GT-R in 2007, Nissan replaced the RB26DETT with the VR38DETT, a 3.8-liter twin-turbo V6 engine.

Engine Specifications:

• Engine Code: VR38DETT
• Displacement: 3,799 cc
• Configuration: V6 twin-turbocharged
• Power Output: 480 hp (early models) to 600+ hp (NISMO versions)
• Torque: 588+ Nm

Unlike the RB26DETT, which had a high-revving inline-six design, the VR38DETT was a more modern engine with an aluminum block, dual VVT (Variable Valve Timing), and increased displacement. While some purists missed the RB26, the VR38 provided superior performance and efficiency, keeping the GT-R competitive against modern supercars.

Conclusion

The Nissan Skyline GT-R’s legacy is inseparable from its engines. From the race-bred S20 to the legendary RB26DETT and the modern VR38DETT, each powerplant contributed to making the GT-R one of the most respected names in the automotive world. Whether you are a fan of classic JDM engineering or cutting-edge performance, the GT-R’s engines have always delivered unparalleled excitement on the road and track.

For enthusiasts and collectors, the RB26DETT remains an icon, symbolizing the golden era of Japanese sports cars. Meanwhile, the VR38DETT continues to push boundaries, proving that the GT-R remains a force to be reckoned with in the world of high-performance automobiles.
