the 200lbs is an estimate...but about 50lbs for a whole a/c system remove (lines, compressor, compressor bracket, evaporator, electrical switch)...then i removed the entire interior including radio/speakers...also when i swapped out the old d16b6 (hf engine) for the si i also removed several meters of wiring for a previous alarm system and a/c system...also under the dash i removed lots of other wiring that wasn't needed...the spare & jack were also removed
