Slant six in a Miata ? Why ???

I wonder though....Why put a slant six in one of those cars? Why not a V6 like a 3.6 Pentastar or an LA series engine?
Opinions?
Not a engine I would choose to do. But, he decided to. I feel it falls under the “Why not” Category. We had a fella here sometime back who decided that a 360 in a Mitsubishi Starion was a good idea. I think that was a car. It was something like that. It worked out for him. It ran low 11’s IIRC.

What MoPar engine would you make fit into an import?
Just because is the reason, or, I have nothing better to do, or...... LOL!
