Would it be possible to turn a 4.11 final drive tranny into a 3.9 FD?

I'm curious why you want to go back to a 3.9?

Umm, not without replacing a lot of things in the tranny. Might as well just go get a 3.9 tranny and matching rear diff.

some backstory: I am going to be replacing the tranny in a '92 SS. I have found a great match (STi ver II, 4.11, but short RA ratios).

You will need to change out the ring and pinion in the transaxle with a 3.90 one.

seems like my best bet is a 5th gear from a wrx. I just hope it'll fit...

My 4EAT is on its way out. I'm planning on getting a 5MT 3.9 put in during December...
