someone can add extra the isg to the car.

very good question,everything else seems to be added after market,shouldn't see why this technology couldn't be,but I expect it wouldn't be cheap if it can be done

You would need to seriously consider the benefits of ISG overall compared to the cost of having it fitted. I think it would take a long time to pay for itself, especially in a little 1.4 motor. Surely they don't use that much juice at idle.

I doubt it could be done aftermarket. From what I understand there are several components that would be beefed up or altered to compensate for the different behaviour.

My guess is that it would be totally impractical to try and equip a car with ISG that was not built with it originally.

The ISG is integrated with numerous sensors and ECU controlled interlocks such as : clutch operation, a sensor to detect the car is stationary, a temperature sensor so that ISG only operates when the engine is hot enough, if the car has a DPF the ISG has to be inter-locked to prevent it happening whilst the DPF is regenerating. There is a possibility that the battery charging/alternator systems differ and the starter motor may be special.

I reckon it would prove cheaper to trade the car in for a new one which has ISG. And all to save (in my case) no more than 5% in overall fuel consumption.
