Hi guys, i have in my cavalier a supercharger kit with the 2.4 ltr LD9, i would like to put pistons forged in my engine, my engine itīs standard, what will be better to place of 0.20 overbore or 0.40.
I have listened that in engines turbos or supercharged itīs convenient to reduce the relationship of fuel and air with the pistons overbores itīs increases this relationship, thanks for the help guys
0.020 so that it gives you that extra bore but still that factory piston stability of the wall you do not want to bore it out too much cuz you'll wind up weakening the water and oil jackets and its just a mess do it .020 over and call it a day.
