No skyline is epa or dot approved in the united states. A dot legal skyline r33 and state reg skyline are not the same thing 95% of every skyline is not dot approved and illegall. If the car was legally converted by motor x or gnk the only two company's that at one point legally converted the r33, both are not in business anymore. Even then 1/4 of the cars here that people paid legally are not dot legal that's why both company's ended up in the legal mess. The only skyline that nthtsa and the epa will now concider is the r33 gtr from june1 96 thru june1. 98 or the motorx converted r33. States like fl,ga,sc,nc have tons of state reg skylines but they are not legal dot or epa. Btw they are over 45k and range to a new skyline price depending on the model,
