Ok.. A stock 1990 CRX Si weighs 2174 pounds. I found that on these forums. But how did they weigh "stock" Was "stock" full of oil, coolant and gas? Did it have A/C?? The reason I am asking, is I just weighed my car. It weighs 2160 pounds. It is a 1990 Si, No A/C, Full tank of gas, full interior (rear shelf included), B18A1, stock rims, Stereo with the rear converted to 6X9's and an amp. I have done some very light weight reduction to it (removed the spare cover, jack, tire, etc, etc) Shouldn't my car weigh like 2270+? P.S. Gas weighs 5.8 - 6.5 pounds per gallon, depending upon additives and temperature. The 90 si holds 11.9 gallons of fuel. Thats 73.185 pounds difference.
