If you could find one of the old HKS single kits that were discontinued, they would be your best bet. Mine craps all over it flow wise, but I would need the car here to fabricate it.
Otherwise, get into the fabrication forum and ask around, I am sure someone can help you. I could make some parts for you and ship them up worst case.
It's very tight up there, but a single turbo hidden under the head low mounted is pretty low key. Send me a PM if you would like to see photos of my creation, even if it just gives you ideas...
