Difference between M52 and M54 Engine

I recently came accross a BMW 323ci and the owner says that the car is of the year 2002.

As far as I know, BMW's up to 2000 where built with the M52 engine and from 2000-Recent with the M54. Am I correct?

Also the 323ci line was until 2000 or not?

What are the differences of the M52 and M54 engines? I searched around but couldn't find anything.

Thanks again for any help guys

Yes, you right! Regarding differences-not much, some tech. updates and little more horse powers

M54s are aluminim blocks, m52s aren't. You get more hp, and better anti-knock algorithms. There may be some other things, but this is what I can thinki about off the top of my head.

This is quite interesting.. http://www.bmwworld.com/engines/m54.htm
Also this which makes me think twice if the 323 has the M52: http://www.bmwworld.com/engines/nikasil.htm

323i/ci 1999 and 2000 E46 have M52TU(technically updated) engines.
M52 engines were installed on E36 cars !

Nice!!!!!!!! Didn't notice that TU in the end.. Thanks!! This minimizes the difference between the M54 and will hopefully make my decision easier

Now why did they stop producing the 323?
