The automotive tuning world is filled with enthusiasts who are always looking to maximize power and performance. Among the most popular engines for modification are the Toyota 2JZ and the Nissan RB26. Both engines have a strong following and are known for their potential to produce impressive horsepower figures. In this article, we will explore the power levels and costs associated with building a 620 HP setup for both the 2JZ and RB26 engines, specifically focusing on builds that incorporate APEXi and HKS components.
Understanding the Engines
The Toyota 2JZ and Nissan RB26 are both inline-six engines that have become iconic in the automotive community. The 2JZ is best known for its role in the Toyota Supra, while the RB26 is famous for powering the Nissan Skyline GT-R. Both engines are capable of handling high power outputs with the right modifications.
Toyota 2JZ Overview
The 2JZ engine, particularly the 2JZ-GTE variant, is a turbocharged powerhouse with a strong aftermarket support system. It features a robust iron block and aluminum DOHC cylinder head, allowing for significant power upgrades with proper tuning and components.
Nissan RB26 Overview
The RB26DETT is a legendary engine that has gained fame for its performance capabilities. Like the 2JZ, it has a strong iron block and aluminum head. The RB26 is known for its high-revving nature and can achieve substantial power with the right modifications.
Power Levels: Achieving 620 HP
Both the 2JZ and RB26 can be built to produce 620 HP, but the approach and components used can vary significantly. Below, we will break down the typical modifications required for each engine to reach this power level.
2JZ Build for 620 HP
A typical 2JZ build aiming for 620 HP would include the following components:
- Upgraded turbocharger (e.g., APEXi or HKS)
- High-flow fuel injectors
- Aftermarket fuel pump
- Upgraded intercooler
- Performance exhaust system
- Standalone engine management system
- Upgraded camshafts
- Stronger internal components (e.g., pistons and rods)
With these modifications, a well-tuned 2JZ can easily achieve 620 HP while maintaining reliability.
RB26 Build for 620 HP
For the RB26, the following components are typically utilized to achieve 620 HP:
- Upgraded turbochargers (e.g., HKS)
- High-flow fuel injectors
- Aftermarket fuel pump
- Upgraded intercooler
- Performance exhaust system
- Standalone engine management system
- Upgraded camshafts
- Stronger internal components (e.g., pistons and rods)
Similar to the 2JZ, an RB26 with these modifications can be tuned to produce 620 HP while ensuring engine longevity.
