Taking out more advance is not a good idea, first of all, power wil drop, so why setting more boost for more power and taking back out the power with less advance. And second, when you really start to back off advance, the exhaust valve will start to glow, can fail and can and will promote pinking on his own.
Honest, building an engine on standard pistons is ok but stay round 0,7 mbar max. It will make, if correct build round 200 Bhp. For all the rest, 1 bar and more, fit forged pistons. You can buy forged pistons very cheap today. If you feel this is the place to save money on your turbo brick, you are doing things wrong. Save money on other places but not on a piston for turbo use over 1 bar. For example, your don't need a modded head, nor do you need an other camshaft etc..
