What's the Titanium Connecting Rods

Titanium connecting rods have been used for decades in high-end applications where the strength and longevity of steel is required, but the lightweight characteristics of aluminum are desired. That comes with a price; titanium rods typically are typically four times the cost of a billet steel rod. The other drawback is that titanium rods do have a fatigue life in race applications and are typically switched out every 40-80 hours. Cars like the Acura NSX, some Chevrolet Corvette models, and Porsche 911 GT3 favor titanium rods, but their cost along with the exotic nature of the vehicles they reside in is reflected in the overall cost of the vehicle.
