The Honda B20 engine is a four-cylinder DOHC engine. It was first introduced in 1988. It delivers 158 horsepower and 112 ft-lbs of torque. It also has a smaller displacement and the ability to remove the Catalyst. These engine characteristics make it ideal for a variety of uses.
The Honda B20 engine is available in several Honda models. Its higher compression ratio of 9.6 allows for higher power output and torque. It can produce 150 to 158 HP and 126 to 150 lb-ft of torque. The B20 was developed to replace the JDM RB series of straight-6 powerplants. The JDM RBs were manufactured from 1985 to 2004 and found their way into many Japanese models.
Adding high-flow fuel injectors is one way to increase the power of your B20 engine. Other methods include porting and polishing, sports catalysts, and forced induction. There are also internal engine upgrades available, such as a competition cam or twin charging conversion. Some people also use a performance exhaust. Another option involves crank and piston upgrades. ECU mapping will unlock the full potential of these modifications.

The Honda B20 engine is a four-cylinder engine produced by Honda. This engine is part of the B series of DOHC / SOHC automotive engines. It was first introduced in 1989. These engines feature higher compression rates than their predecessors. The B20 is capable of producing between 158 hp, as well as between 126 and 150 ft-lbs of torque. It replaced the JDM RB series of straight-six engines that were built from 1985 to 2004. These engines were installed in several Japanese models.
There were also Honda B20s in the CR-V mini sport utility. These engines were similar to the LS engines. However, the B20B’s cylinder head gasket differed from the LS head gasket. If you’re looking to upgrade your Honda B20 engine, the B20B’s cylinder head can be swapped out for a stock cylinder head. It’s possible to get 200 hp from a mild B20B on pump gas and around 150 lb-ft of torque from a stump-pulling B20.
The Honda B20 engine was a relatively small displacement engine for the B Series family, but it made a good enough effort to make a car feel fast. While the first generation B20 had 126 horsepower and 130 lb-ft of torque, later models topped out at 150 hp and 140 lb-ft of torque. While the B20’s horsepower output was lacking compared to its predecessors, its smaller displacement was ideal for making “Frankenstein” engines.
The B20 engine series was produced for several years by Honda. It was first used in 1990s models of the Honda Prelude S and Si. Later, the B20B version was introduced in the Honda CR-V. The JDM version of the engine featured higher compression pistons and 146 hp.
Hondas have catalytic converters that help to convert around 90% of the vehicle’s toxic emissions. These are essential to the environment and vehicle health, and if one becomes defective, it can greatly affect the driving experience. Honda dealers are able to help with the process of replacing a catalytic converter.
Car thieves target Hondas because they have hybrid systems and their catalytic converters can fetch a higher price when sold. They steal the converters using jacks or angle grinders and resell them on the black market for as much as $1650. You can protect your vehicle against theft by buying a comprehensive car insurance policy, which will cover the cost of stolen catalytic converters.
Modifications to the Honda B20 engine can be performed to increase horsepower and torque. Some of the modifications include installing high-flow fuel injectors and porting and polishing. Others involve upgrading the fuel pump and internal engine components. You can also install a competition cam, twin charging conversions, and performance exhaust systems. Often, an ECU mapping is required to unlock the full potential of the modifications.
The Honda B20 was one of the least desirable engines in the B Series, but car tuners quickly realized the potential of the LS/VTEC system. While stock B20s produced a modest 126 horsepower, later B20Z2 versions delivered 150 horsepower and 140 lb-ft of torque. While the power output was underwhelming compared to its predecessors, the smaller displacement made it an excellent candidate for “Frankenstein” engine projects.
If you’re thinking of giving your old Honda B20 a rebuild, you’ve come to the right place. This article will provide you with information on what to do and what tools you will need to start the process. If you don’t want to spend a lot of money on parts, it’s still possible to do it yourself, but you need to know the basics first. You can start by reading the B-series Engines Workbench by Jason Siu, which contains more than 600 photos, charts, and illustrations to show you how to disassemble and rebuild a B-series engine. It explains what to look for when rebuilding a B-series engine, and includes considerations for stock and performance engines. You’ll also learn about VTEC, and many other performance components and accessories.
While the Honda B20 wasn’t the most exciting engine in the B-Series, it did prove popular for enthusiasts. The first generation of B20Bs had 126 horsepower, while later models like the B20Z2 produced 150 hp and 140 lb-ft of torque. Compared to its predecessors, the B20’s horsepower output was not that impressive, but its displacement and reliability made it the ideal “Frankenstein” engine.
