Well this isnt a power adder. If you are willing to tear down the motor that much. You could have rods, pistons, vavles, block whatever all cryo treated. Would make everything much much stronger and have a more reliable motor that can handle much more HP. You could also do this to your tranny parts so your trans could handle all the power you throw at it as well
