RB20DET
The RB20DET engine, first produced in 1985 as part of the RB20 series, played a significant role in Nissan's lineup. This 2.0-liter engine is known for producing approximately 210 horsepower, making it a potent engine for its era. This engine came in various forms, including naturally aspirated and turbocharged variants, catering to different Nissan models.
The RB20DET is characterized by its double overhead cam (DOHC) valvetrain and electronic fuel injection. In 1988, Nissan introduced the Silvertop RB20DET, which featured enhancements like the Electronic Concentrated Control System (ECCS) and a larger turbocharger, resulting in an increased power output of 215 horsepower.

VQ30DD
Nissan's VQ30DE is another notable Skyline engine, utilized in the Skyline V35 generation, which was synonymous with the Infiniti G35 in the U.S. This V6 powerhouse boasts a 3.0-liter displacement, and its heart is a 60-degree V-shaped aluminum cylinder block, which contributes to its lightweight and efficient performance.
Over its production years from 1994 to 2007, the engine exhibited a range of power levels depending on its application and evolution — the earlier iterations generated around 192 horsepower and 205 pound-feet of torque. With aftermarket support and a few upgrades like JWT cams, valve springs, cold air intake, headers, and performance exhaust, this engine could deliver even more horsepower and an aggressive sound.
Some enthusiasts even explored increasing displacement to 3.3 liters using a VQ35 crank, rods, aggressive camshafts, and a turbo kit, which can apparently increase power outputs well beyond 300 horsepower.
In 1997, Nissan introduced a special version of this engine, the VQ30DD, which featured direct fuel injection and variable valve timing (CVTC). However, the real star has to be the turbocharged variant — paired with a Garrett M24 turbocharger, it delivers an impressive 280 horsepower and 285 pound-feet of torque. The VQ30DD 3.0L engine found its way into several Nissan models in addition to the Skyline, like the Nissan Maxima, Gloria, and Infiniti I30.
