What makes a 2 liter?

[6keb1@qlink.queensu.ca (Kareem)]

To spell it all out: as Al said, there is a difference in both bore and
stroke, but the difference in bore is small enough such that the
combustion chamber in the head of the 1.8 will also match up to the 2.0
block and work very effectively. Of course, the oil and coolant
passages match perfectly.. As to the compression ratios of the 2.0 block
w/ 1.8 head  I think it's around 10.8:1   - the increase over the 10:1 of
the 1.8L engine being due mostly because of the reduced
squish area of the 2L pistons. HTH.
