Various people posted saying I was wrong and that you very rarely see any increase in power.
Karl even stated that he has bolted a 1.8 bottom end on instaed of a 1.6 and got no extra power.
he must have missed something as power should have jumped over 10 bhp just by changing the bottom end.
I have not read the whole thread but I think I can see where you are coming from... e.g.
If I had a 1600cc K series lump and swapped the bottom end over for an 1800cc version using the complete 1.6 head the power would rise from 111hp to 118 (as long as a suitable map is used) BUT if the 1600 engine's head was flowing the most it could already then changing the capacity is not going to increase the power.
