IIRC the lack of lead was not a great concern in those early VW engines, since they can run easily on ethanol and gaseous fuels.

What kind of hardware would you be considering to use to convert an EFI engine to wood gas? Do you think the same systems currently used for those CNG and LPG conversions would be OK?

The engine must be tuned with higher comp and maybe introduce a supercharger, it improves the efficiency

You could eventually try some variable-compression setup, allowing you to retain some limp-home mode on gasoline/petrol. Unless you would rather use ethanol for that matter
