kv6 180/190 difference

Does anyone know with 100% certainty what the differences between the kv6 180 and 190 are?



Been searching but the best anyone seems to have is guesswork



Some sujestions....

Larger exhaust bore on 190

Larger intake bore 60mm on 190 (57mm on 180)

Different ecu map

And finally the bit that worrys me.... different cams.



180 engines seem to be easier to find than 190's so if the differences are easily swapped then it expands my options for finding an engine.



Im fairly sure the 160 would need cams which means new belts etc (when swapping cams over) which increases costs so want to avoid that
