i got a motor i just ripped apart. i was wondering what pistons should i put back in it?? Cast or Forged. i heard forged is good if you want to use NOS(big shot) or turbo, but when you start the car it sounds like a diesal truck and got to check the oil alot. I'm thinking Cast but in the future i want to run NOS (little shot), My friends say build the motor the right way and put forged but i'm leaning to the cast.
