Yup...Motorex WAS the company...Here is the rest of the story from wikipedia...
A California company, Motorex, sacrificed a small number of R33 GTS25s for the purpose of crash testing. They submitted their information to the US National Highway Traffic Safety Administration, and petitioned them to allow 1990-1999 GT-Rs and GTSs to be imported, at the condition that they were modified to meet federal motor vehicle safety standards.
Many Skylines were subsequently imported through Motorex. This lasted until late 2005, when the NHTSA became informed that not all 1990 through 1999 Skyline models would perform identically in crash testing. Motorex had submitted information for only the R33, and told the NHTSA that it was sufficient for all R32, R33, and R34 models. According the further review by the NHTSA, only 1996-1998 R33 models have been demonstrated as capable of being modified to meet the federal motor vehicle safety standards. After that, only these 1996-1998 models are eligible for importation. In March 2006, Motorex ceased all imports and Motorex principal Hiroaki "Hiro" Nanahoshi was arrested and held on $1 million bail on financial, kidnapping, and assault charges.
I think it would be a royal pain to legally import & drive one in the states. That said...I heard of one guy who got one registered somehow in his state but this was years ago...I'm sure there are at least a couple Cosmos in the States...but to import one now seems like it would be impossible...
