The debate between the Toyota 2JZ and the Nissan RB26 has been a longstanding discussion amongst car enthusiasts, particularly those interested in building high-performance engines. Both engines have proven their capabilities in motorsports and street applications, but the cost of building a reliable 550+ horsepower engine can vary significantly between the two. In this article, we will conduct a cost analysis of building reliable 550+ HP 2JZ and RB26 engines using Cometic gasket sets.
Overview of the 2JZ and RB26 Engines
The 2JZ and RB26 engines are both inline-six configurations, known for their strength and tuning potential. The 2JZ is often found in the Toyota Supra, while the RB26 is the heart of the Nissan Skyline GT-R. Both engines have their loyal followings and distinct characteristics, which affect their build costs.
2JZ Engine Overview
The Toyota 2JZ engine is renowned for its robust iron block and aluminum DOHC cylinder head. It features a forged steel crankshaft, which contributes to its high-revving capabilities. The 2JZ-GTE variant comes with twin turbochargers, making it a popular choice for those looking to achieve significant horsepower gains.
RB26 Engine Overview
The Nissan RB26 is also a formidable engine, featuring an iron block and aluminum DOHC head. It is equipped with a forged steel crankshaft and is known for its strong aftermarket support. The RB26 is twin-turbocharged, similar to the 2JZ, and has a reputation for handling extreme power levels.

Comparison of Costs
When comparing the total estimated costs for building a reliable 550+ HP engine for both the 2JZ and RB26, we can see that:
- Total for 2JZ: $10,100
- Total for RB26: $11,200
The 2JZ engine build is approximately $1,100 less expensive than the RB26 build. This difference can be attributed to various factors, including the cost of parts and the availability of aftermarket support.
Factors Influencing Cost
Several factors can influence the overall cost of building these engines, including:
- Parts Availability: The availability of aftermarket parts can greatly affect costs. The 2JZ has a more extensive aftermarket support.
- Labor Costs: Depending on the region, labor costs can vary significantly.
- Performance Goals: The desired horsepower and performance can dictate the choice of components, impacting overall costs.
- Condition of the Base Engine: The condition of the engine block and head can influence the need for machining or additional parts.
Conclusion
In conclusion, both the Toyota 2JZ and Nissan RB26 engines are capable of producing impressive horsepower figures. However, when it comes to building a reliable 550+ HP engine, the 2JZ tends to be the more cost-effective option. With a total estimated cost of $10,100 compared to the RB26’s $11,200, the 2JZ offers a slight advantage in terms of budget. Ultimately, the choice between these two engines may come down to personal preference and the specific goals of the build.
