Stopped by the Minnesota DMV this week and found that registering the car should be easy - as far as the person at the counter was able to tell me. No emisions requirements, just need a MSO (manufacturers statement of origin), pictures, major components used with receipts and of course all of my details. Sounds straight forward enough.
I've also been trying to educate myself on turbocharging. I found a handy tool that allows you to enter the type of engine (diesel or gas), number of turbos, whether its intercooled, engine capacity, maximum rpm and boost setting. The result is a specification for a Garrett turbo and estimated HP with a given air flow. The site is here:

I used 6000 rpm (probably conservative for the 1UZFE) and tubo boost of 8 psi - it looks like with twin GT25 turbos (full ball bearing) about 415 hp is possible. The interesting thing is to play with some of the numbers. With 7000 rpm and 10 psi of boost the power jumps to 524 hp. I don't know how accurate this tool is but try it out.
