1) It would be cheaper and way easier to just buy a BS that has the larger engine.
2) The engine bay is rather cramped. I’m not sure where you’d put an extra turbo and it’s associated plumbing.

The OEM turbo is a twin scroll unit, so it already performs the function of a second turbo in a typical twin-turbo setup. That aside, there is only one exhaust manifold on the engine, and it already has a turbocharger installed on it. Where would you install a second turbo.
If anything, you would swap the turbo for a larger turbo instead of adding another. That can be kind of tricky to pick the right size to get increased performance (not just a higher peak power) and maintain drivability. If you have the Badlands, there could be some starting points to look at in the Ford Focus world.

Now we're really getting somewhere, supercharged and turbocharged!
Yes, you are correct. I didn't mean to imply it wasn't a possibility, although a few years ago I would have wondered.

A lot of Focus ST ppl put a 2.3 crank and pistons into the 2.0 engine block to make it a 2.3. Then bigger turbo, ported head, better intake and exhaust, and tune ect ect.
But never heard of anyone second turbo on a three or four cylinder.

You might check into swapping out the compressor wheel to gain a little boost or add a tuner. I don't know if either is available for the 1.5. I did both on my old 7.3 PS and gained about 100 hp.
