Harry, Adam sold that S13 we built with RB20, suspension, shit cage, R200 LSD, 5 stud conv, 32 GTR brakes, race pads, new wheels/KU36 tyres, Velo seats, fresh paint etc, all rego'd for $6k. All it needed was a computer, RB25 turbo n tune. Bloody good value I reckon.
What I like about S13 owners is many of them take a good swift kick in the balls well and are very negotiable
