Yet, the engine is not efficient enough for some reasons. Having a complex design and pattern, it is not worthy enough to go for the other Honda variants. And that can be a major drawback to witness about this engine.

Keeping this factor aside, this engine is simply great in performance for better power delivery and lower weight dimension.

The B16A Generation

The B16A2 and B16A3 are not the only models that are available in this sector. They mainly belong to the B16A category. In a real sense, these engine models were known as the higher performer and powerful ones at that time.

It was designed for the 4th generation chassis of Honda. That is why it was not efficient enough to go with other models. All the Civic models from 88 to 91 were the perfect ones to go with this engine pattern.

If still, the better one has to find out, B16A3 can be the choice for having a lower weight ratio. However, the A2 has a better universal mode rather than the A3 one.

The famous Infiniti brand has two well-known models available to them. And they have been placed as a comparison named G37 vs Q50. Wishing all of you will have a great journey with this discussion.
