We are all familiar with the commonly available forged steel connecting rods on the market, but what are your thoughts on billet aluminum rods? LOTS of drag race and V8 street/strip builds use aluminum rods. They have apparently been shown to withstand power loads similar or greater to comparable steel parts, and reduce the weight of your rotating assembly so much (especially with lightweight pistons) that the inertial load decrease would permit easily another 1000-2000rpm with the same margin of safety.
Now, maybe I'm just reading into this too much... but I can get custom billet rod sets made for under $900 easily. Why don't I ever see Z31 people do this?
Billet AL connecting rods are CNC machined from special extruded aluminum alloy plates that provide a combination of high strength, high fracture toughness and very good resistance to fatigue crack propagation at high stress levels. Another small benefit is they can come highly polished, so it moves through oil windage easier because less oil clings to the rod during operation.
