What You'll Learn
Fuel injector size
The B16A1 and B16A2 engines typically use 240cc fuel injectors. This is a common size for Honda injectors and is also used in other engines in the B-series, such as the B18C. The 240cc injectors provide a good balance between fuel flow and atomization, resulting in efficient combustion and power output.
However, there are variations in fuel pressure and latency between different applications of the B16A engine. For example, the early B16A engines had a fuel pressure of approximately 30-35 psi, while the B16A1 engines had a fuel pressure range of 35-41 psi. The B16A2 engines may also have different fuel pressure and latency specifications, which can impact the overall performance and fuel efficiency of the vehicle.
For those seeking to upgrade or modify their B16A engine, there are larger injector options available, such as 500cc or 600cc injectors. These larger injectors can provide increased fuel flow and support higher engine performance. However, it is important to note that upgrading fuel injectors requires careful configuration and tuning to ensure safe and optimal performance.
In summary, the fuel injector size for the B16A engine is typically 240cc, but there are variations depending on the specific engine variant and application. Upgrades and modifications are possible with larger injectors, but they require careful consideration and technical knowledge to ensure proper functionality and safety.

Fuel pressure
In the context of the B16A engine, fuel pressure plays a crucial role in ensuring the smooth and efficient operation of the vehicle. The B16A engine is known for its high-performance capabilities, and maintaining the correct fuel pressure is key to unlocking its full potential. According to sources, the B16A engine typically operates with fuel pressure in the range of 35-41 PSI (240-279 kPa). However, some variations may exist, with one source mentioning a fuel pressure of 38 PSI for the early B16A engines.
It's important to note that fuel pressure is closely linked to the fuel injectors. The fuel injectors deliver fuel into the engine's combustion chambers, and the correct fuel pressure ensures that the injectors function optimally. Any issues with the fuel injectors, such as clogging or malfunction, can lead to low fuel pressure and impact the overall performance of the B16A engine.
To maintain the proper fuel pressure in the B16A engine, it is crucial to pay attention to the fuel pump and the fuel pressure regulator. The fuel pump plays a vital role in transmitting pressurized fuel from the gas tank to the engine. A faulty fuel pump may struggle to deliver fuel at the correct pressure, leading to performance issues. The fuel pressure regulator, on the other hand, helps maintain the desired fuel pressure by adjusting the pressure in the rail based on the pressure in the manifold.
In conclusion, fuel pressure is of utmost importance in the B16A engine. By understanding the relationship between fuel pressure, the fuel pump, and the fuel injectors, one can ensure optimal engine performance, efficiency, and longevity. Regular maintenance and prompt attention to any issues related to fuel pressure can help prevent performance-related problems and keep the B16A engine running smoothly.

Injector latency
In the context of the B16A engine, injector latency values are crucial for proper fuel injection system operation. The B16A engine is known for its high-performance capabilities, and ensuring precise fuel delivery is essential for achieving optimal power output and engine efficiency. The B16A engine typically uses 240cc injectors, and the fuel pressure can vary depending on the specific variant of the engine. For example, the B16A1 service manual recommends a fuel pressure of 240-279kPa (35-41psi) when the regulator vacuum is disconnected.
When upgrading or modifying the fuel injectors in a B16A engine, understanding injector latency becomes even more critical. As mentioned in the Ozhonda Forums, users discuss the technical specifications of B16A2 OEM fuel injectors and the importance of injector latency values. They highlight that injector latency affects the amount of time it takes for the injector to fully open and close, and it is crucial for achieving the desired air-fuel ratio. Additionally, they mention that an increase in fuel pressure will lead to higher dead times, impacting the overall performance of the engine.
To calculate the new injector correction and latency when upgrading fuel injectors, the following formulas can be used:
- Old SIZE / New Size = Correction
- New Latency - Old Latency = Latency Correction
By following these formulas, users can ensure that their new fuel injectors are properly configured and calibrated for optimal performance. It is worth noting that injector latency values are typically provided by the injector manufacturer, and it is important to source this information from reputable companies or suppliers.

Fuel flow rate
The fuel flow rate is determined by the fuel pressure and the injector size. The higher the fuel pressure, the more volume of fuel will be delivered. The B16A engine has a fuel pressure of 35-41 psi, or 240-279 kPa, and uses 240cc injectors.
Fuel pressure can be adjusted with an FPR (Fuel Pressure Regulator). A higher-pressure FPR will increase the fuel flow rate, and vice versa. The dead time or latency of the injectors will also be affected by changes in fuel pressure.
When upgrading or replacing injectors, it is important to consider the injector size and fuel pressure to ensure the correct fuel flow rate is achieved. The formula for calculating the injector correction is: Old Size / New Size = Correction. For example, when upgrading from 240cc OEM injectors to 500cc injectors, the correction would be 240 / 500 = 0.48 or 48%.
It is also important to consider the voltage load points of the injectors, as the dead time or latency will vary depending on the voltage. There are typically 6 voltage load points: 6v, 8v, 10v, 12v, 14v, and 16v.
When upgrading the fuel pump to a high-pressure unit, it is important to make adjustments to the fuel pressure and volume accordingly. A high-flow, high-pressure fuel pump may cause issues with overfuelling, so an adjustable FPR is recommended to relieve pressure and maintain the correct fuel volume.

Fuel injector compatibility
Fuel injectors are components of an engine's fuel system that spray fuel into the engine's intake air, providing power to the vehicle. Fuel injector compatibility is essential to ensure optimal engine performance and fuel efficiency. Incompatible or improperly installed fuel injectors can lead to various issues, including reduced engine power, increased fuel consumption, and even engine damage.
When it comes to fuel injector compatibility for the B16A engine, there are a few key factors to consider. Firstly, it is important to distinguish between the different variations of the B16A engine, namely the B16A1 and the B16A2. The fuel injector specifications and requirements can vary between these two versions.
For the B16A1 engine, the stock fuel injectors are typically 240cc, and the fuel pressure is specified to be within the range of 240-279 kPa (35-41 psi) when the regulator vacuum is disconnected. It is important to ensure compatibility with the stock ECU and to consider the fuel pressure requirements when upgrading or replacing fuel injectors for this engine.
On the other hand, the B16A2 engine also utilizes 240cc fuel injectors, but the fuel pressure specifications may differ slightly. According to some sources, the fuel pressure for the B16A2 can be around 38 lbs, which translates to approximately 30-35 psi. It is important to refer to the technical specifications provided by the manufacturer or reliable sources to ensure compatibility and proper installation.
When upgrading or replacing fuel injectors, it is recommended to refer to technical specifications, such as injector size, latency, and dead time values, to ensure compatibility with the specific engine. Additionally, seeking advice from reputable forums or consulting with professionals can provide valuable insights and guidance on fuel injector compatibility and installation procedures.
