The main reason i was looking at the z24 pistons was the 15cc dish as this
would allow me to run 2mm squish ( hopefully small enough to be effective) with
my 42cc head and still get a comp ratio under 8. unlike my current L20 setup
where i use a 3.5mm squish to get the comp down.I also like the flexability of
the L18 and its ability to rev.I think this would better suit the larger turbo
i'm building.
