Not true. It can do 15psi on 87.

Psi is irrelevant, It depends on the turbo. CFM is what is important and not to mention the k03 on the 1.8 Volkswagen SETUP for turbo didn't even run on 87 octane.

Ok, well, Honda makes 177hp out of a 1.5L turbo engine that runs on 87 pump gas, and gets 45mpg highway. Just saying.

Has advanced ignition and cam timing change, direct injection, atkinson cycle and extensive friction reduction measures.

All those are why... cam and ignition timing are huge..

Hell 5.0 coyote can run 87 octane... they dont make their advertised power tho

What a few others have said and I will agree on most of the engines that are turbocharged mainly do it for power and just use a smaller motor but yes there are few Motors out there like the Earth dream setup that are specifically for fuel mileage and they do it very well.

(Using talk/text) so if their is any grammar or fragmented sentences. My bad

Edit: because i have the turbo off my civic we can try on your miata at 15psi.... im not sure it will like it.
