As I wrote in my first comment 'I have no mechanical knowledge of engines' just basics. So as explained ,COP would be better fitted to a turbo engined car,so I will put that to the side since I prefer ...

Would the turbo head fit without any problems on the NA block since the blocks are the same? Also can COP's be fitted to a webered engine, or does this require any major mods... I think that the COP s ...

Speaking of spark, my 924 has a factory fitted electronic ignition system, the car is a 1981 model, so its not a early type, could anything else better this unit, or shall I stick to it?
