Fork lift pistons

["Hall, Phillip" <Phillip.Hall@msfc.nasa.gov>]

Hey ye smarts ones -

Getting a handle on prices/specs to do a R16 turbo motor and I want to use
the fork lift pistons (dish).  How much is the dish in cc's.  How expensive
and the availability of these pistons.  My motor is running 188 to 186 PSI
in the cylinders so I need to drop compression.  Any help would be great!

Come to think of it - is there a correlation between cylinder pressure and
compression ratio?

Thanks
Phil
