Engine swap 2003 330i 3.0l into a 2002 330i

What is your question?

I have a 2002 330i in which the engine is worn out... Rings are worn out. 285k miles. I wanted to install another 3.0L out of a 2003 330i and wanted to know if it would work and be a direct fit... Both engines are the standard 225hp engines.... ? Thank you.... Tim

What makes this problem better or worse?

Will a 2003 330i E46 engine work in a 2002 330i E46 330i?

How long has your 2002 BMW 330i had this problem?
