Where I live, 91 is plentiful and 100 is rare at stations. Even with 100, detonation will be an issue with 9.4-1 compression and this car's capabilities. A 9.4.1 compression would be the most we would entertain. Just weighing the advantages and disadvantages.
We have discussed this motor with many very knowledgeable people. All have recommended running a compression ratio lower than 9.4-1. However, they vary as to what compression would be best.

There is a little more to it. KA is running just shy of 4.5L dislacement. She was designed for and set up with nitrous along with being designed for 2.5 bar.

The more the better. If it's a street car, try to keep it at least 9ish, if it's just a "race" car or highway blazer drop it to 8.5 or 8.75 and crank the boost.
I've had turbo cars with CR's in the 8's and they suck for the street. You will get beat by everything except Yugos until you're in boost. I bumped comression from 8.5:1 to 9.45:1 in my V8, made the same power and the car became an animal off boost. I think 9.4 is fine, especially if you have a built motor or at least rods. Just my experience.

the only problem is that the car in that youtube video is a turbo, not a GT2.
