"The Sileighty (also written as Sil80) originated through early street racers in Japan who owned Nissan 180SXs with damaged front ends. Because the Silvia's front panels and lights were lighter and cheaper than the 180SX replacement parts, many drifters used these parts instead. Unknown to the public until the release date, these end user modifications inspired a Japanese auto shop, Kids Heart, to produce a small number of so-called "official" or "real" Nissan Sileighties. It is on record that 500 cars were made by this shop, and were only sold in 1998.[1] Essentially the kouki (late model) 180SX Type-X tuned for drifting, the cars are distinguished from their home-built brethren by the distinctive "Sileighty" name on the rear dressplate and quarter windows. The Sileighty includes performance-oriented modifications such as a new ECU, a stiffer suspension system, an improved limited-slip differential, and an increase in turbocharger boost from 7 psi (0.5 bar) to about 13 psi (0.9 bar), resulting in approximately 230 hp (172 kW), versus 205 from the standard Silvia's SR20DET or the 180SX's 175 hp (130 kW) CA18DET. The Sileighty is not recognized by any government as a Nissan manufactured model; instead it is generally treated as the model of the original car before modification."
