    Does any one know why there is a difference in the connecting rod assemblies & part no's for a 2015 Vector & a 2018 Vector. I can't see why they would change this unless there was a problem. I have owned other Vectors & never had a problem.

    Didn't they "lighten up" or redesign parts within the motor in 2016?

    Are these new updates better or worst. I always thought this engine was bullet proof, why change it.

    Apparently no good for boost. But N/A, less rotating mass is good.
