    Stock crankshaft with upgrade to Pistons and connecting rods

    Hi, I am purchasing a used, running 4tec 2014 block from a Non supercharged PWC with 140 hours on it for $500. I am going to rebuild it into a supercharged unit with the ET68/140 supercharger on it. Is replacing the pistons with forged type and connecting rods (Perhaps carrilo) be an issue for the crankshaft as is? Thanks

    Not an issue at all. I would go with the CP 9.5:1 compression pistons and Carrillo rods. Also upgrade the flywheel bolts while you are in there. Also be sure to replace the rocker shaft bolts and I recommend upgrading to the ARP head studs
    Great buy on that ski!!!
