Compression Ratio NZ frankenstein
Can anyone give me a definitive answer on what the compression ratio is on a 2NZ head put onto a 1NZ block? I'm looking for the bump in displacement but to keep my newer head. I have both motors already. 3rd gen 2014 Yaris

As far as I know the only difference between a 1NZ and 2NZ is the stroke length. The heads should be identical.
