Ok so I'm doing the 2jzgte pistons and rods on my is300.ive weighed the ge and gte pistons rods Etc and obv yes they weigh more I know that the cranks are the same they say but do I have to balance the crankshaft cause I'm adding heavier internals or has anyone had luck just doing the swap and not balancing just worried about getting a bad vibration . I tried to look first before I posted this thx for any info

Nothing to worry about. Balance isn't important between crank and rods/pistons, but each independent piece - all pistons should weigh the same, big and small rod ends, etc.
