Upper and Lowers are a different design
Curious if they weight the same?

Balance shaft has nothing to do with the pistons weight.
Balance shaft is here because this a V4 motor which is not naturally balanced contrary to a square four.
And would the balance be run by the front or the rear crankshaft, this has absolutely no importance regarding balancing.
