It's also only a tiny bit below the Ferrari 458 (88ft-lb/L). I really doubt Mazda is going to push their engine for a Miata quite that hard. I wouldn't be surprised if they were around 150ft-lb, but 170 would be very surprising out of a 2L in that price class of car.

I think those cars you mentioned make so much torque because they have everything tuned for a very specific range that's quite high up. This engine will definitely not have such a high torque peak so it'll have trouble reaching producing that much torque even with everything optimized for torque at that point.
That said, the super high CR could bring it up to like 160 ft-lb pretty easily if the cams and piping are in harmony, and that would be at a very reasonable rev range too. A solid amount of power for a 2200lb car.
