Carrillo Nissan/Infiniti/Datsun VG30/VG33 Pro-SA 3/8 WMC Bolt Connecting Rods

If you're rebuilding or upgrading the engine in your 1990-1996 Nissan 300ZX, especially for higher performance levels, strong connecting rods are essential. These Carrillo Pro-SA connecting rods are built to handle the demands of boosted VG30 and VG33 engines, offering a significant step up from stock components. They are designed to be a reliable foundation for your engine build, ensuring power is transferred efficiently and safely.

Carrillo is well-known for making robust engine parts, and these rods are no exception. They feature a Pro-SA design, which is a popular choice for performance builds. The rods are forged from high-strength steel and come equipped with 3/8 inch WMC bolts, which are known for their reliability and ability to withstand high clamping loads. This combination of material and hardware means these rods can handle increased cylinder pressures and RPMs that come with performance tuning. The I-beam design offers a good balance of strength and weight, which is important for engine balance and responsiveness.

When installing these rods, it's important to ensure proper balancing of the rotating assembly. Carrillo rods are precision-machined to tight tolerances, but balancing the crankshaft, pistons, and rods together is a critical step for engine longevity and smooth operation, especially in a performance application. These rods are designed to fit the VG30 and VG33 engines found in your 300ZX, making them a direct replacement for the factory rods when building a performance engine. Always refer to the manufacturer's installation instructions for specific details regarding clearances and torque specifications.
