Actually an inline 6...undersquare Supra inline 6 that is pretty easy to get to 450tq...
...and I didnt really mean "good gas mileage" by "practical", but with a standalone and will power I'm certain it will do so.
By practical I mean all those little things that add up..10 minute spark plug changes, ease of cam location/placement, room, smoothness, ease of working on, lightweight when compared to a V, non-interference, etc. etc.
Miata would have trouble with 200 or more HP and would require bracing and serious drivetrain upgrades
