As far as I'm aware, there's no kits to turbo a fiesta mk7 yet.
A few things to consider if you are going to do it:
Oil feed/return pipes
And what turbo you are going to use of course!
If someone has turbo'd the mk6 st engine then you may be able find out what they've used to get ideas, but would be good to see a turbo 1.6ti-vct
