if you are planning on an internally balanced engine (netural flywheel and balancer) - then yes.. if your planning on an externally balanced assembly.. I dont think you will..

If they weigh within 3-5 grams (Each) of the old ones I wouldn't worry about it, but if not then yes.

Make sure you include the wrist pins when you weigh them, because there are different weight wrist pins. (all of them in your set should be the same, but they may not be the same weight as the ones in your car)

Yes just weigh the old piston and pin and then weigh the new piston and pin, if they are the same then you are ok.
