if you're looking for a cheap way to do this, forget it. yeah the evo's are dirt cheap in japan, but even the VIN swap method will cost you the price of a salvaged mirage. and the obvious RHD to LHD swap you'd have to do (the DMV people are stupid, but not that stupid). you have to swap the firewall too. importing any car requires alot of research, time, money and continued investment (flying in parts). unless you're ready to put in the effort (and dough) save yourself the heartache and just buy something here you can afford.
i used to drive a street legal 6, and the only way i could was it had a MFG plate on it
