I bought a new set of tires about 2 weeks ago, after 2000km the front tires looks like this:
Front tires
The rear tires doesnt look worn at all. What is wrong?

Get an allignment. Your front toe is way off.

I switched from 19" wheels to 16". Could this be enough to cause this?

Were the old tires worn like that too? Did you do anything else to the suspension like lowering it?

A workshop swapped the motor and entire drivetrain from a jdm gt4 to my gt4. When they did the job the 19" was on it. When i got it back i almost immidiatly changed to 16" with new tires. I just wonder who to blame. Me, the workshop that swapped the engine or the workshop that changed the wheels an tires.

If you didn't get an alignment after the engine was swapped, then you.

An alignment should be done basically any time the suspension has been altered. Disassembling/reassembling it counts as altering -- you really cannot eyeball it back into place.

If you did not maintain the same overall diametre between wheel and tire combinations, then your alignment can easily be thrown off (though that is typically camber, rather than the toe misalignment RabidTRD mentions).

any time you put tires on......you should get an alignent

When I dropped my car and cambered the front a bit, my tires looked like that because they went \ / in the front and / \ in the rear. I had to drive on them for a week because I forgot to schedule for allignment. Shreds tires instantly
