    There is one in the project section, it requires cutting the hull, if it were me I would take the stock charger off and put a vortec kit on.

    He is right we have one on island that they moded. The stock intake is too high, so you will have to cut the hull inorder for it to fit.
    What the guys here is they split the 15f in two top and bottom, then they installed the top part of the ultra to the 15f bottom.
    The engine then had more then enough room.
