Question type: Maintenance & Repair
I have a 2004 325I automatic trans. I want to eventually replace the engine as it
is pushing close to 240,000. What would be the biggest/ newest year 3 series
engine I could put into it?

Post this on a BMW forum but I would rebuild the engine you have and include some performance improvements.
An engine from a 2005 330i or a 2006 330ci. You will need to perform some reprograming I would suppose as well. Plus you would want to replace your brakes as the 330's had larger brakes.
