Okay so, since I didn't found anyone more who could fix the Audi rust, paint and stuff, gonna send it for Ward, on Spain.
Also gone to Departament of Motor Vehicles to make the Audi plates, all gone well there!
And, fitted the 4JJ on the Alfa, provisory stuff, but good for now.
EDIT: Forgot to say, 4JJ is converted to gasoline:
Replaced fuel lines, TBI, new injectors (changed diesel ones for spark plugs)
Then I made a flange for a higher head gasket, a bit more than 1mm for make less compression!
Runs like hell, love it!

Also got the coilovers for Alfa so the car weight looks way better now, brakes arrived too, just need to install then, gonna do it later.
Now, still looking for rims for it, wish to find it in a few days!
