CP Forged Piston Set (BMW N55)
Our CP pistons are a great match to compliment our Carrillo rods for these built engines. These pistons are designed to handle 1000 HP in the standard configuration and can handle up to 1600 HP with upgraded wrist pins. If you plan to make over 1000hp we highly suggest the HD wrist pin option. Our standard piston options include stock bore as well as a .002" oversize piston. We highly recommend the slight oversize to allow your machine shop to rehone your block for the new piston set. Other configurations will be custom ordered with a 5 week lead time (expedites are possible). If you have any questions about what CR or bore diameter is best for your application it is best to call us and talk to us over the phone. E-mails are also responded to quickly. These pistons are stock compression ratio but other compression ratios are available as a special order.
