I think this will help for people who keep asking "will this engine fit" im also posting this in the Older Genrations Corolla thread.

Toyota Motor Corporation has produced a wide variety of automobile engines. The company follows a simple naming system for their modern engines:

1. The first numeric characters specify the engine block's generation
2. The next one or two letters specify the engine family
3. The suffix (separated by a dash) specifies the features of the engine:
