Will a new(er) engine fit in my 1977 Porsche 924?

1977 Porsche 924 with an Audi 2.0 litre. I was researching and found on Ward's top ten list that Audi’s 2.0 TFSI I-4 Engine was on the list and looks surprisingly similar in all respects. For small block Chevy there is a interchange guide book (that I own) and I am looking for the same book for this vehicle (or the Audi engine itself). Point me in the right direction and I'm your biggest fan! I've spent several days in google but with no answers...Thank you.
