Only read a few threads on this, but mostly about the nova. I just changed engines, 1.2 8v to 1.4 8v spi on a corsa. I was thinking, is there any gains in changing the valve section - not the cam section. Since the two engines are disimilar - the 1.2 has a distributer the 1.4 doesn't. Also, the 1.4 is hi torq - with the gas recirc - so would I have to use the 1.2 inlet as well? Or would it not work?
Cheers for any advice.
