I asked the guys in the aussie forum these questions relating to this engine (L24E skyline).

Just thought some of the yanks might be able to shed some light on the issue (as I only just found out this engine was availible in the states in the maxima). Just wondering if anyone can confirm how many CCs this head is. I've heard around the 40-42cc mark, although I havent measured it myself (dont have access to a burrette).

The reason its so critical is that I am about to use this head on an L28 block with flattop pistons, and too small a chamber will blow my compression ratio out, and I dont wanna have to rebuild it again with dished pistons (which I also have).

Can anyone who has used this head with flattop pistons or who has CC'ed the combustion chamber confirm the size/compression ratio expected ?

Every 810/910/Maxima L24E I've ever seen has an N47 head.

opps...my mistake. I assumed that because it was the same engine produced in the same year, it was the same head. Oh Well.
