E82 120d performance upgrades

Hey guys,

I have done a lot of searching but couldn't find what I am looking for. I found a lot on the various 320d platforms as well as the 120d E81/E87/F20/F21 platform, but nothing really on the 1-series E82. I'm not sure if the information from one of the other platforms can be taken, because unfortunately I don't know if any of these engines are the same as the E82.

I would like to know what performance upgrades can be installed on the E82 120d, along with any recommendations, pricing and experiences you might have regarding these upgrades.

Thanks in advance.
