The 2JZ engine, renowned for its performance and tuning potential, has become a favorite among car enthusiasts and tuners. To achieve optimal performance, especially in builds aiming for over 600 horsepower, selecting the right fuel pump is crucial. This article will delve into the best fuel pumps for 2JZ builds, focusing on the Walbro 450 and the DW400.
Understanding Fuel Pumps for 2JZ Builds
Fuel pumps play a vital role in ensuring that the engine receives the necessary amount of fuel for combustion. For high-performance builds, particularly those pushing beyond 600 horsepower, the standard fuel pump may not suffice. Upgrading to a high-flow fuel pump is essential for maintaining power and performance.
Walbro 450 Fuel Pump
The Walbro 450 fuel pump is one of the most popular choices among 2JZ enthusiasts. Known for its reliability and high flow rate, it can support builds aiming for 600+ horsepower.

Comparing Walbro 450 and DW400
When choosing between the Walbro 450 and the DW400, several factors should be considered. Both pumps have their strengths, and the best choice often depends on the specific needs of your build.
Flow Rate
The Walbro 450 offers a higher flow rate, making it more suitable for builds that require maximum fuel delivery. However, the DW400 still provides ample flow for most high-performance applications.
Installation
Both pumps are relatively easy to install, but the DW400’s compact design may offer an advantage in tighter engine bays.
Reliability
Both pumps are known for their reliability, but the Walbro 450 has a longer track record in the performance community, which may provide peace of mind for some users.
Conclusion
Choosing the right fuel pump for your 2JZ build is essential for achieving optimal performance, especially when aiming for 600+ horsepower. Both the Walbro 450 and DW400 are excellent choices, each with its own set of advantages. Consider your specific needs, installation space, and performance goals when making your decision.
