there are a few cars like the one u want...there is the full out racing model, and then there is the street legal "loaded with nismo parts" model...although i think the car u want is the one from gran turismo and is only from gram turismo and just highlights the badassness of skylines and nismo combined, but i dont think it is an actual car, now it could be built, yes, but i dont htink it exists as of yet, although i could be wrong, but here are some pics and links of nismo tuned gt-r's
