    Read a ton of stuff on the C15 6NZ lately. Many claim that it is 15.2l others say 14.6l, claiming the Acerts are 15.2 by way of 6NZ bore but longer stroke. So which is it ? Thanks.

    I think its the normal 14.6L. The 7CZ is the big 15.8L I believe.

    Yeah there is some serious miss information on the internet. I've seen people post links to places showing a 6nz as 15.2. Which it is not! 15.2 started with the bxs acert.
