What You Need to Know About a Honda B20 Engine

A Honda B20 engine is a type of inline four-cylinder, DOHC automotive engine. It was introduced by Honda in 1988. This engine is capable of producing up to 190 horsepower. It’s commonly found in vehicles such as minivans and motorcycles. Learn about the different parts of this engine and its power potential.

To start with, you need to know the head type of your Honda B20 engine. It is generally the LS P75 head type. Usually, the head has a knock sensor on it to tell if it’s a high or low-compression motor. These engines have 84mm bores and 89mm strokes. They are similar to the B18B engine, but the firing order is different.

The first generation of Honda B20 engines was released in Japan between 1995 and 1997. These engines were used in the JDM Honda CR-V and Orthia. This version of the engine came with a 126 horsepower power rating. The production of these engines stopped in 2002. The later models, the B20Z2, were more powerful and produced up to 140 lb-ft of torque. While the output of the B20 was disappointing compared to its predecessors, the displacement was a great asset.

The B20 engine is a natural-aspirated engine with a displacement of 1973 cm3. It does not have a VTEC system and has a compression rating between 8.8 and 10.8. Its redline is around 6,500 RPM.

Performance of a honda b20 engine

The performance of a Honda B20 engine can be enhanced in a number of ways. One of the most popular ways to increase power is to install VTEC heads. These add a notch to the power curve, while a B16 engine head swap is also an excellent way to boost power. Another popular mod is to install a B17 crank, which has more power potential. Other factors that impact torque gains include the ecu map, the injectors, and the cam profile.

A b20 with stock pistons and rods has poor combustion space and a low compression ratio. If you want to get a higher horsepower from your engine, you can install forged low compression pistons and a new head. If you want to boost the power further, you can install a b16 head assembly, ARP head studs, and a Hondata ECU. A B20 with stock rods and a pr3 head is not recommended for tuning.

While the B20 was not an immediate success, it eventually won over many car enthusiasts. As a result, many enthusiasts began to use it as a bottom end in their own Frankenstein swaps. These included combining the head and bottom end of a 2.0L engine. This allowed them to extract a good amount of high-end horsepower and torque. The first B20B models produced around 126 hp, with later B20Z2s getting up to 150 hp and 140 lb-ft of torque. Although this was a disappointment compared to its predecessors, the B20’s large displacement was an advantage.

Common head work on a honda b20 engine

While the B20 engine is a solid unit, it should be regularly serviced to ensure optimal performance. Carbon buildup can sap power and cause flat spots. Here are some tips to remove carbon buildup and improve engine performance. You can also learn how to tune your engine to get the maximum performance from your tuning parts.

For increased performance, you should upgrade to a B16A or B16B VTEC head. The b20 head assembly is not suited for high-rpm tuning, and the B16A/B16B head is a better choice. In addition, you need to upgrade your cylinder block, distributor, and crank.

Changing a Honda head requires removing the old head and installing a new one. This is a time-consuming process, but the end result will be well worth it. If you want to make the most of your B20 engine, be sure to send it to a reputable machine shop. Ensure that the shop you use is experienced in machining performance Honda heads. You should also consider titanium springs and retainers, which will improve the motor’s performance. If you plan to use aggressive cams, you may need to port the new heads to provide extra flow. Some heads will also need head milling to achieve the best result.

Power potential of a honda b20 engine

A Honda B20 engine can be tuned to produce more power, up to 15 percent more. This process involves adding more air and fuel to the engine. The engine sucks in air in a certain phase called the “suck phase” and then mixes it with fuel as it is burned. A number of factors influence how the air and fuel mix, including the design of the engine intake. Adding a performance exhaust or a supercharger is one way to maximize the power potential of a B20 engine.

The Honda B20 engine first appeared in the 1990s in the Honda Prelude Si and S models. It is capable of producing between 104 and 135 horsepower. In 1997, a new version of the B20 engine was released that had more power. This engine had a redline of 6,500 RPM. It was later fitted in the Honda CR-V. This newer version of the B20 engine has higher compression pistons and can generate up to 146 hp.

The Honda B20 engine is one of the biggest and most powerful engines in the Honda B-series. It is a naturally aspirated, 16-valve, non-VTEC engine. Its block is made of aluminum and the cylinders are cast iron. There are different models of the B20 engine, but all come with the same 16-valve, non-VTEC belt-driven double overhead cams.
