Here are two turbo kits available for the Mazda 6i:

The later link's turbo kit has been tested much more on the Mazda 3's and 6's. The owner Jaun has recently installed larger turbo on his Mazda 3 and just reached 508 whp and a 11.9 second 1/4 run.

how about a turbo for the Mazda6s.

There are no turbo kits for the Mazda 6 S due to the complexity of turbocharging a transverse V6.
