The C32B is a highly tuned DOHC V6 used in the Honda NSX, which produces 290 hp (216 kW) and 224 lb·ft (304 N·m). The engine is essentially an update to the C30A and does not share commonality with the C32A. Honda increased displacement to 3.2 L (195 cu in) through the use of larger 93 mm (3.7 in) pistons over the 90 mm (3.5 in) used in the C30A. To accommodate the larger pistons, Honda used an advanced metallurgical technique on the cylinders called Fiber Reinforced Metal (FRM), in which an ultra lightweight alumina-carbon fiber is cast into the traditional aluminum alloy for enhanced rigidity. This process allowed thinner cylinder walls to be used while providing acceptable cooling characteristics. The C32B also used 32 mm (1.3 in) intake valves, which are 1 mm (0.04 in) larger than those in the C30A.
