The LS/B20 VTEC Engine

In this article, you will learn about the LS/B20 VTEC, stock internals, and upgrade options. This will help you make an informed decision about which engine to buy. This article also includes some information on long-term vehicle performance. There are three major factors to consider: horsepower, longevity, and cost.

LS/B20 vtec

The B20 Vtec engine is the same engine found in the Honda CR-V, but is a bit more powerful. It has a displacement of 1.6L and produces 227 horsepower and 167 lb-ft of torque. It is part of the B series engines, which also include the B16/B18 and B20B/B20Z.

A B20 Vtec engine should be well maintained in order to get the most horsepower out of it. If there are hidden problems with the engine, you should have it rebuilt and tuned. Once you have a healthy engine, you can increase its horsepower to 250 and more!

Stock internals

If you’re looking to make a turbocharged B20 engine more powerful, there are many things you can do to increase its horsepower. A few of the most important things to consider are the internals. You need to have forged pistons and rods, a wideband o2 sensor, and the right sized fuel injectors. You also need to tune your car’s computer.

If you want to make more than 250hp, you will need to upgrade the head and intake. Other necessary parts include an intake manifold and 70 mm throttle body, Supertech valves, and valve guides, a lightweight flywheel, and a Hondata ECU.

Upgraded internals

You can increase the horsepower of your B20 engine by upgrading its internals. By increasing the valve size and angle, you can increase the flow of air inside the engine. This increases the amount of fuel that the engine can burn. Adding a supercharger or additional turbo can also increase your power output. These upgrades are more difficult to perform, but they will give your engine a big boost in power.

Another way to increase horsepower in a B20 engine is to upgrade the air flow sensor. While the OEM air flow sensor limits air flow at lower levels, a new one can provide up to four bars of air to the engine. Aside from adjusting the air filter, you can also install headers, which take air from the air filter and allow it to enter the cylinders.


The B20 engine is one of the most reliable and long-lasting engines on the market. It has an average lifespan of 220 000 miles. In some cases, the engines have even exceeded 400 000 miles. In addition, they require minimal maintenance and are generally trouble-free. However, it is important to make sure that you warm up your engine before driving it.

The B20 engine was first introduced in Japan during the 1990s. It was found in the Honda Prelude S and Si. Its power rating was 104 hp, and it also delivered a good amount of torque. In 1999, the B20 was updated to the B20Z series. This version came with higher compression pistons and a more powerful ECU. This engine was used in cars until 2001, when the K20A series was introduced.


The B20 engine has an advantage over B18 engines when it comes to reliability. It is more efficient and reliable in high speeds and higher RPM. A B20 engine can generate up to 300 horsepower, while a B18 engine will only reach that power when you modify its internals and swap out its heads. It is also more durable and reliable when it is new.

The B20 engine is reliable and solid, but it can still lose power if it experiences carbon buildup. Even though it consumes a large amount of fuel, it won’t drain your pocketbook. It is also easy to maintain and repair if necessary. Make sure you warm it up before driving it, though.


The B20 engine first appeared in Honda cars in the 1990s on the Prelude Si and S models. These engines can produce 104 to 134 horsepower and torque. Later, the B20B series was introduced in the Honda CR-V. This new series offers a slightly higher horsepower and torque. The new engines also have higher compression pistons, resulting in higher power and torque.

The B20 engine is a variant of the B16/B18 engine. It has a 2.0-liter displacement and can produce between 126 and 150 horsepower. It should be noted that these numbers will vary between different models. The B20 engine is typically upgraded through an LS/VTEC conversion. However, there are other ways to increase the horsepower and torque of a B20 engine.

Biodiesel potential

Biodiesel is a renewable fuel that is increasingly becoming popular in vehicles, especially in hybrids and electric vehicles. Its energy density is similar to petroleum diesel, but it is more expensive. Because it has little financial incentive, manufacturers are reluctant to offer a warranty for it. However, manufacturers are allowing a certain percentage of B20 in their engines to improve fuel economy and accelerate performance. A 20 percent biodiesel blend may yield slightly better fuel economy and acceleration and cost the same as conventional diesel.

Biodiesel can be produced from a variety of feedstocks. Forest and agriculture wastes, including cooking oils, can be used to produce biodiesel. The process is environmentally friendly and can triple production capacity in a single year.
