Hi everybody , Im in the oil crisis scenario and i need some very low emission .
so what are the parameters that have a significant effect on emission ?
catalystic sure but even with 10 tech pool im way over-spec.
Can someone help me ?

Hi Francois,
try aluminium block & head and hypereutectic pistons. If you have the right fuel system, too, the emissions shouldn’t be a problem anymore.
