1968 Fiat 850 Spider
Very interested in this motor. Anyone have an opinion?
A conversion rarely comes out with a weight as low as the original, and especially not with enough battery for useful range. Occasionally the original engine is such a boat anchor that the conversion doesn't increase weight (a cast iron inline-six, for example), but that's rare, and the 850 engine should be light... it might not weigh much more than just the electric motor which replaces it. One 850 owner who removed the engine says it weighs about 150 pounds. The controller, wiring, and EV accessories (DC-DC converter, charger, BMS, etc) will weigh 50 pounds, so the motor plus that stuff is as heavy as the engine, and so every bit of battery weight beyond a tank of gas is an increase over the car's original weight.As for the weight, the factory says 1600lbs but that includes the gas engine and a full gas tank. So I think it is safe to say that the car would weight about the same with all the modules, the motor(the motor is just over 100lbs), and all the other components.
