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.
