Its beyond even that man. Look at the discharge flange on that, it would be a custom downpipe as well. Just way to much work to be worth it.
Like i said, IMO your best option is to join a few VW forums and sell that turbo there. They are worth a mint, its a great turbo.
I can actually hook you up if you wanted. My friend owns a turbo shop and i could get you a normal used exhaust housing for that thing. T2 flange .80 AR would be perfect for that turbo on the Ka. The problem would be rigging up the wastegate. You would need a new actuator and bracket.
