What cars does a 3.1 multi-port V6 fit into?

I have a 1990 Beretta GTZ that had a 2.3 high output, and it was blown when i got it so i put a 3.1 multiport in it. It works good but it was a ton of work, i even had to change two of the motor mounts. i don't know what else it can fit in but it fits into my car and works!
