So which Nissan models are NISMO?

Nissan's homepage now only features two NISMO cars, the 370Z Coupe NISMO and the discontinued GT-R NISMO, both of which are sold out. 

However, a new Nissan Fairlady Z NISMO model is predicted for the summer of 2024, according to the Japanese magazine Best Car.

The 400-horsepower twin-turbo 3.0-liter "VR30" V6 from the ordinary Z could be used in the Fairlady Z NISMO. 

Nevertheless, Drive predicts that the NISMO model will be more potent because of "a sports exhaust system and updated engine calibration."

Finding a secondhand NISMO model is most possibly your best bet for purchasing   

a Fairlady Z NISMO for the foreseeable future because Fairlady Z NISMO

orders have been halted as of July 2022.
