The B20B Engine

Honda B-Series was introduced in the market in the year 1989. The B-series are a family of inline four-cylinder DOHC automotive engine. B-series is more focused on its performance option. This B- series is distinguished by alphabets and numbers together. The first letter is for sure B, after that it has some digits like B20, B21, B18 etc. Then again there is code like C1, B1, B2 etc.

One of the best performance engines is JDM Honda B20B Engine. This engine model comes in two specs: 1995-1997 and 1998-2002. Both the engines have some similar and dissimilar features which are the best.

Similar features:

1. Both the specs come in non-VTEC (Variable valve timing and Lift electronic control)

2. Rod length of both the specs is same i.e. 137mm (5.4 in)

3. Bore and stroke configuration of both specs of JDM B20B engine is same which is 84mm (3.3 in) and 89mm (3.5 in) respectively

4. Displacement in both the subcategories is same which is 1972cc (120.3 cu in)

The 1998-2002 spec is an improvement in the earlier version where there are some configuration changes.

Improvement:

1. Power of earlier version was 145hp (108 kW) @6200 rpm and for the newer version was 150hp (112 kW) @6300 rpm which means improved version engine is more powerful

2. There is a lot of improvement in torque value. In earlier version, torque value is 178 N·m (131 lbf·ft) @ 5200 [4500 rpm 2.0GX-S] whereas, in new one, torque is 184 N·m (136 lbf·ft) @ 4500 which means new version is more flexible and can express more force in a given gear

3. Compression value; which tells about the condition of engine valves; in 1995-1997 and 1998-2002 specs is 9.2:1 and 9.6:1 respectively

4. Redline for former one is 6700 rpm whereas for latter one is 6500 rpm. Redline tells about the maximum engine speed of vehicle without damaging it

5. There is little difference in Rev limit as well. In the first version, it is 7300rpm and in newer version it is 7200rpm which restricts its maximum rotational speed
