E92Fan over at the UK section has been running upgraded pistons and rods, both from Pankl Racing / CP-Carrillo. Lower compression ratio (I think identical to the one Alpina uses on their B3 BT), much lighter materials on the pistons and titanium rods. Runs very well, he just doesn't have time to spend on his car right now unfortunately.
