The creation of the Sileighty then followed by another version of the Silvia known as the Onevia. Based on the chassis of the S13, the front end of the Silvia would be removed and replaced with the front end of a 180SX. The Onevia was never retailed as a complete car in Japan (though it was in North America: the coupe version of the 240SX was essentially a left-hand drive version of the Silvia with the 180SX/240SX nose).
