I don't think it is a vacumm line, it's rather a cable, coaxial as you say. If the older version has to do with the crank pulley, do you think I can still drop the older engine into the car ?????
I don't really know about fuel management system, the fuel distributor and airflow and the lambda controls appear to be the same in both models. everything else regarding odds and ends appear to be the same.
I was thinking about using all the sensors and wires from the original 88' car. The only thing I wanted to install here was the engine block with head and possibly the intake manifold if both appear to be the same thing...
The only thing that worries me is whether the car will start with the older engine
