To lower the compression properly for a turbo setup, pistons with more dish volume than stock are required. For high compression setup, piston dish volume is the main option as well, or you can also weld volume into the combustion chamber which i would not suggest for any kind of novice.
higher compression than stock is not the way to go when turboing, although there has been some discussion on the subject. I believe demcj was pondering the comparison of higher compression/low boost vs. lower compression/higher boost. The latter is a proven method and naturally detonation is less for any amount of boost with lower compression. Considering same engine/cylinder head design.
Heres a piston dish volume compression ratio comparison chart for both ka24e and ka24de.
