    What needs to be forged to push more boost?

    I am planing to push around 12lbs to 15lbs later down the road. What I would like to know is do I need to forge the entire engine or are there just a few trouble areas like the Valve Springs. I would imagine the pistons, rings, H Beams maybe Cam. Thank you in advance for the schooling.

    According to the Hot Rod article that Ed posted, nothing. Just have a good tune. Search for "Big Bang Theory" in the forum search, if interested. It's a good read.

    I would recommend the crank, connecting rods, pistons, ect., if it were me. Better to safe than sorry, IMO.

    damn good read. I will just save my money and buy a LS6 block and build it slowly. I will change my rings and springs. Up the boost a lilbit at a time. Thank you Knight.
