An 80's Nissan, made from the front of a Silvia S13 and the ass end of a 180SX. This was done because when someone fucked up the front of their 180SX, Silvia S13 fronts were lighter and cheaper. When this style began to grow popular, Nissan factory produced it, but only for a few years.
Guy: "Hey, I like your Sil'Eighty. You make it?"
Jim: "Yea I had a nasty reck a few weeks back, replaced the front."
