Sorry if it's old news
But any how. I was just looking into the K6A. And Found that Mazda uses these engines in their KEI class cars. Which I found interesting.
As most of you know / or have read the KEI FUN on autoweb.
If not here's the full story.
I found it a good read

Mazda Threes...
If you’re interested in three-cylinder performance, the current Mazda K6A 660cc DOHC, 12-valve turbo engine should be on your shopping list. With an 8.4:1 static compression ratio, variable valve timing and air-to-air intercooler this baby engine puts out 47kW at 6500 rpm and 106Nm at 3500 rpm.
A naturally aspirated version with variable valve timing and 10.5:1 compression generates 40kW and 63Nm. Both engines come fitted to the Japanese market Mazda AZ Wagon Kei classer.
