Balancing 1UZ Rotating Assembly
I've got a set of forged NASCAR Lentz rods, and will be placing an order for a set of JE custom pistons once I get all the correct measurements down. I will also have to offset grind the rod journals to accept the smaller 1.888 rod bearings.
My main concern, which I didn't give much thought about until now, is that the weight of my rods are 537 grams while most aftermarket off-the-shelf rods are in the high 500's to low 600's. Coupled with lighter forged pistons and the total weight of material removed from the crank rod journals, how much more difficult would it be to balance the whole rotating assembly?
Is there usually a limit as to how much material can be removed from the bob weights during balancing?
Also, would the fact that the 1UZ cranks being steel, as opposed to cast iron, add to or take away from any difficulty in balancing?
