My completly stock 1980 280ZX w/ automatic tranny, t-tops, power windows and mirrors,A/C,CD changer and head unit, r180 rearend, lots of rust, with no driver, no fuel, and no spare tire, no jack or tools weighs around 2700 pounds. The extra turbo stuff and R200 rearend shouldnt weigh more than 100 pounds, So a turbo 280ZX weighs around 2800.
I think that number means thats the most it should weigh with people, fuel and cargo.
