Did AR make 1,6 116s with Injection, I didn't know.
With out dought, it will be a nice cruiser and prevent too many penalties in your license.
For transaxle fun and easy of setting the engine up I would go for a 75 TS, 148 HP with out cat. It,s as fast as your 156 JTS (when all power is there).
I have fund memmories of my 75 2,0L and Giulietta 2,0 2,0L. But as reliable as my 156 was they wasn't but they never let me down. Then I used my cars as part of my job, and both always brought me back for dinner
