Saturn 1.9 DOHC Engine

My son decided to see how long his 99 Saturn would run without oil. As it turns out, it wasn't too long. I now have to look for an engine for him. Can someone tell me exactly what letters, numbers, etc. to look for to find a motor that will bolt up with no mods? Can I just get any 1.9 DOHC? Thank..

Can you put a Saturn 2000-2 v6 engine in a Saab 9000
