The F20B engine is based on the H22A and features a bluetop head. This engine has a compression ratio of 11, a VTEC system and a 62.5mm throttle body. It was used in the JDM Honda Accord and Torneo. The F20B engine has a higher horsepower and torque rating than its predecessor, the F20A. The F20B engine can reach speeds of up to 7,800 rpm.
Low-compression version of H22A4
The H series is Honda’s line of naturally aspirated four-cylinder engines. They aim to provide a good balance between affordability and performance. The F20B engine, a low-compression version of the H22A, was sleeved down and used in international racing. Its basic design was excellent, and its power output potential was very impressive.
The F20B engine was developed for the Honda Accord and the Honda Torneo. It had a DOHC VTEC cylinder head, a low-compression version of the H22A, and a new T2T4 gearbox. This engine was used in both European and Japanese cars. The low-compression F20B version has a bore diameter of 1.9 inches, which allows for higher midrange torque.
If you’d like to boost the F20B in the H22A4 version, you need low-compression pistons, H-beam rods, ARP head studs, and a TD04 turbocharger. You shouldn’t build your own turbo. The turbo kit comes with a turbo manifold and a downpipe, and it’s best to buy a 2.5″ exhaust system.
145 hp (108 kW) at 5,600 rpm
In the United States, a car with 145 horsepower (108 kW) at 5,600 RPMS is called a “supra.” This type of car was manufactured from September 1967 to September 1974. In Australia, the engine produced 103 kW. Similarly, it produced 156 lb-ft of torque at 3,600 rpm. The turbocharged version of this vehicle was introduced in 1983, increasing the power output to 160 PS (107 kW).
Inline four with multipoint fuel injection
Honda F20A/B engines are inline fours with a single cylinder. These engines have a displacement of 240 cc and 310 cc, respectively. They have a 1-3-4-2 firing order and are part of the Honda F-family. The F20A/B engines were produced until 2001. The F20C is still used in some vehicles, but it has been replaced by the K20A.
Honda originally installed this engine in the 1989 Accord and Ascot. This engine was fitted with a 219.5-mm high aluminum cylinder block with a 145-mm rod length. Its pistons have a diameter of 85 mm and a 31-mm compression height. The engine was derived from the H22A engine and has a DOHC VTEC head. This enables it to produce over 195 HP and 240 lb-ft of torque.
Cost
An F20B engine is less common than H22A or B18C1 engines. Both engines can be upgraded, but the F20B is more difficult to upgrade since parts for it are not as widely available. This also means the engine is more expensive to upgrade if you want to increase its horsepower.
The F20B was produced from 1997 to 2001 for the Honda Accord. It was available in automatic and manual transmission versions. The manual version was slightly better due to bigger cams and an intake and throttle body from an H22. The manual engine costs around $1,000, and the automatic version costs around $2,000 or more.
Maintenance
The F20B engine was built by Honda in Japan from 1993 to 2002. It was installed in several Accord models and was available in SOHC and DOHC versions. It was also available with or without a VTEC system. The F20B engine was part of Honda’s F-series of internal combustion engines, which also includes the F18B, F20C, F22B, and F23A. A common complaint with this engine is oil leaks. It is also known to have irregular running. Most commonly, this is caused by a faulty Idle Air Control Valve.
