    I'm looking for a supercharger kit for a boared s52, and I found the Active Stage 2 supercharger kit based on stock internals and compression ratio, but I was planning on putting in new pistons and rods to handle more horsepower as well as having a lower compression ratio for more boost.

    My fiance is calling and tried to boost a friend's car.
