need some help

If I am building a b18c1 and plan on running 15 lbs or so boost would stock compression ratio work or will I need to lower/raise? I am going to put pistons and rods in it and would like to know the best set up. thanks

Stock compression works well with low to mild boost. There is no need to lower compression unless you want to run high boost on pump gas. If you plan to run E85 or Race gas you can run both high comp/high boost.
