a little OT - but that 10sec guy always makes really stupid posts..
Back to topic - yes definitely balance your rotating assembly - and that rotating assembly is exactly what that one poster already said - crank, pistons, rods, flywheel, bearings, etc.

serious. i've seen so called "good shops" make tiny mistakes
down to the MM of a measurement and the whole motor goes.
in fact, i built one that i thought was perfect and i didn't recheck turns out i left a TINY miniscule drop of grease on a bearing and it spun.

I'm building a 1NZ and am not currently planning on getting the entire assembly rebalanced. I did weigh big end / little end / total weight on the rods and piston weight, and will be mixing / matching to get even weight from the piston / rod combo across the block. The crank lobes already counterbalance, and the cylinder 1 - 3 up, 2 - 4 down should further eliminate vibration. I'm also only shooting for 150 WHP for daily driving on an auto trans.
Of course, I'm not removing an internal balancer or doubling engine HP. For the tC, especially considering those two things, get it balanced.
