Alfa 156 Giugaro

Euro3 to euro4


I am a new member of this forum and am interested in buying my first own alfa 156. I am looking at buying one with euro3 norm in Germany and importing it into Slovenia. Since my country has higher taxes for vehicles with euro3 than euro4 norm, and I may well see restricted areas (town centers,..) for vehicles based on this cirteria in the near future, I am thinking about converting it to euro4. I am looking at an alfa 156 1.8 TS MY2003 (facelift with the giugiaro look). I noticed that this model can be found with euro4 norm but only if it was built in the second half of 2004.
My questions are:

Is it possible to convert the alfa I am looking at from euro3 to euro4?
If yes, what is needed for such of a conversion? I investegated if the later models have different exhaust systems or some other mechanical tweaks to the enigne to make it euro4 but I found none. Is it therefore only an ECU flash that is required for a conversion?

And is it possible by converting the car to run on LPG (or gas) to also convert it to be an euro4 car?

Best regards

Even if you can convert it to Euro4, you still need to get the tax people to take it as a Euro4, which may not be possible.
