I need convert some karts of supertuxkart 0.6 to 0.8, is this possible?
I also got the blender files.

I thought all the Karts were converted.

That should be possible indeed; you need the latest STK panel, kart and b3d export scripts and a recent Blender version. Also you probably need to mark the wheel objects as wheels in the new STK panel in Blender. If you need further instructions, the wiki is a good place to look - otherwise ask here and someone more knowledgeable than me should be able to help you.

I try to install the pluging in Blender 2.62 (Ubuntu 12.04 LTS 64 bits) copying these files to $HOME/.blender/2.62/scripts/addons
├── B3DExport.py
├── convert_24_to_25.py
├── stkdata
│   ├── stk_kart_object_parameters.xml
│   ├── stk_material_parameters.xml
│   ├── stk_object_parameters.xml
│   └── stk_panel_parameters.xml
├── stk_kart.py
├── stk_material_export.py
├── stk_panel.py
└── stk_track.py

But I can't see the export option in Blender
I also try to copy this structure in /usr/lib/blender/scripts/addons

Thanks in advance.

Take a look at this section in the wiki page:
http://supertuxkart.sourceforge.net/Installing_the_tools_2#Installing_the_scripts_into_Blender
You enable the exporter plugins, copying the files to the right spot is not enough. If they don't show up in the plugin list, that's a whole other issue.
