A Sileighty (also written Sil80) is a Nissan 180SX with Nissan S13 Silvia headlights, front fenders, hood, and front bumper installed, hence the “Sil,” short for Silvia, and the “eighty,” for the 180SX. The Sileighty originated in Japan. Street racers and drifters in Japan did this conversion after a wreck because the S13 Silvia’s front panels and lights were lighter and cheaper than the 180SX replacement parts.

In the United States, it has become common for owners of the 240SX, the American version of the Nissan Silvia, to make their own Sileighties by importing a Silvia front end and installing it onto their car. Sometimes this 240SX/Silvia conversion is referred to as a “Silforty,” but most import enthusiasts insist on calling it a Sileighty because the proportions of the 240SX fastback body are identical to the 180SX components aside from labeling. Converted S13 coupes or convertibles are not considered Sileighties, instead, the car is most commonly referred to as a JDM Silvia Conversion.
