Non turbo. Check this out
You'll most likely pickup some MPGs in the process and you should be able to run on 87 octane most of the time without a problem.

No. In the US octane is calculated by the formula (RON+MON)/2. In the UK and most of the world its simply RON.

Our 87 octane is equivalent to your 91-93 and our 92 is around 95-97 in the UK. Generally speaking the US has lower octane gasoline than the UK and europe but the difference is not as big as the raw numbers would suggest.
