Although a few shops still managed to make tuning options for the latest cars and Intakes are still out there and a couple cam places like Delta Cam, but in general its a barren wasteland of tuning...
There isn't any 93 octane in California anymore, but in the UK 91 is their "regular" unleaded petrol and they have up to 95 octane, and Japan I haven't been able to figure out exactly but they do have higher than 93 as their "high" octane fuel.
Basically, most other countries don't offer as low 87 octane and go higher than 91 or 93. But we do have E-85 which is quite high on the scale but comes with... different issues

Like that fact that it can feed baby seals and can cause global cooling?

Try me for E85 issues, I know stuff, people, or I can find a solution. Although in Cali you are screwed no matter what. Can't help you with that.
RON is higher than US octane because we factor in MON. We get the same grade fuel, we just use a different grade!
I learned of just some of that Subaru N/A stuff when I went looking for a Subaru N/A engine with only 2.0L. The only options were to use the old EJ18 or importing an engine. The EJ204 is decent for a N/A but it was not popular and therefore rare. The FA20 is shaping up to be what I am looking for in a decent chassis.
