Eh, the Miata's never been about big power and in all honesty I think a turbo engine is a poor fit for the car.
At 2200 pounds, 155 horsepower is quite sufficient. It won't be a straight line rocket but 0-60 in the mid sixes to low sevens isn't sluggish.

Eh I wouldn't call a 1.5T big power. Ford's 1.5 puts out 181/185 in stock trim.
