Sadly most of the GTR owners in the states don't know shit about their cars or how it got here. The feds knew about Motorex doing this and looked the other way because the cars were otherwise identical. This is also how they convinced the feds to allow the R34's, they told them the safety changes between the chassis was minimal and the changes were an evolutionary cosmetic change. This floated for a little while but not enough people were paying the inflated price Motorex was charging for them.
