Yes, it is considered to be a good engine (motors are electric, engines are not). The one big flaw is cavitation (do a search on it, since there are tons of posts on it!).

The downpipe can be replaced with an ATS downpipe for less constriction of airflow.

The E4OD tranny is hit or miss. Mine has been a pain yet others have no issues.

Hope that helps! If I am off a little let me know!
