New here and question about Euro2 conversion

Hey, guys.

I have been the proud owner of a V8 3.6 Bj.89 for many days. I'm so excited about the "thickness." So that the joy does not disappear in the first tax ruling, I want to convert the good piece to Euro2. Now my question is which sentences are there and there are serious differences. I found different things about the search function but not really smart out of it. So far I only found a set for the 3.6 on the EGS system with the others (HJS, B&B) I find only kits for the 4.2. A short post with manufacturer/source of reference, best with link would be a big help.

Best regards from Mannheim
