How much power does a B20 engine make?

If you’ve ever wondered what kind of power your car’s engine can make, you’re not alone. But like most things involving cars, the answer depends on a lot of factors—the vehicle itself, its modifications, and even how you drive it. In this article we’ll do our best to answer that question by examining the horsepower potential of four popular engine swaps:

The power of a B20 engine depends on the vehicle in question.

The power of a B20 engine depends on the vehicle in question. The engine’s ability to produce torque is generally more important than its horsepower, as torque is what allows you to accelerate quickly and easily. In fact, the power output of a B20 engine is not significantly higher than that of a B18B engine—a small increase that usually does not make much difference for drivers looking for an upgrade. However, if you are comparing two cars with similar power outputs from their engines (such as two Civics), these differences will be more evident.

A B20 block has five cylinders instead of four or six like other Civic blocks; it can also be used in certain late-model Acura Integras. A 2.0L displacement means that each cylinder holds 0.5 liters of fluid by volume, giving it twice as much displacement per cylinder than a typical 1.8L 4-cylinder motor but less than half as much displacement per cylinder compared with larger V-6 engines found in many sedans today!

The power output of a B20 engine is not significantly higher than that of a B18B engine.

The power output of a B20 is not significantly higher than that of a B18B, and in fact, the typical B20 produces slightly less horsepower than an equivalent B18B. However, if a car has been modified for increased performance (via supercharging or turbocharging), then it may be able to make as much as 200-300 horsepower.

The power output of an engine is measured in horsepower (hp), which is defined as “the rate at which work is done.” In other words, one horsepower equals 550 ft-lb per second: or 746 watts or 3459 foot pounds per minute: or 0.7457 kilowatts (kW). So if you want to know how much power your car makes—regardless of its engine type—you’ll need to know how many kilowatts are being produced at any given moment!

A B20 engine produces more power than a B16A engine.

The B20 is a 2.0-liter engine, while the B16A is a 1.6-liter engine. The larger displacement of the B20 means that it produces more power and torque than the B16A, though both engines are considered to be relatively high compression engines (10:1).

The difference in power between these two engines is approximately 15 hp at 6,500 rpm and 16 lb-ft of torque at 4,800 rpm for the B20 versus 14 hp at 7,000 rpm and 14 lb-ft of torque at 5,000 rpm for the B16A.

That said, there are several things to consider when looking at these numbers:

  • Both Honda Civic models have manual transmissions; only automatic transmission cars use different gear ratios which can affect your dyno results by around 10 – 15 horsepower depending on what gear you’re in (for example an automatic version can produce more power in first gear because there’s less distance between gears). If you have access to test drive an automatic car before purchasing one then do so! Otherwise try searching online or asking friends if they know someone who owns such a vehicle.

A B18B and a B20 are completely different engines.

A B18B and a B20 are completely different engines. The first thing you should know is that both of them are 2.0L engines, so you may be confused by their similar names. If you see an ad for a “B20” on Craigslist or in the classifieds, it’s probably referring to a 2.0 engine from one of these cars:

  • 1994–1997 Honda Civic EX Coupe
  • 1994-2001 Acura Integra G/GS/LS Vtech
  • 1992-1994 Mazda Miata (NB1)

If you have questions about your car’s engine, ask an expert.

If you want to know more about the engine in your car and how much power it can produce, ask an expert. A mechanic or car enthusiast is a good place to start. If you don’t have access to such people, there are many online forums where users share information about their cars and answer questions from others. Another option is to ask a friend who knows about cars when they’re not busy with their own vehicles.


Hopefully this has helped you figure out how much power your B20 engine makes. If you have any other questions about your car’s engine, be sure to ask an expert.
