What material are these Manley connecting rods made from?

These specific Manley Pro Series connecting rods are made from 300M vacuum degassed steel alloy. This material is chosen for its exceptional strength and fatigue resistance, making it suitable for high-performance and demanding engine builds.

Are these connecting rods suitable for a stock Nissan GT-R engine?

However, they are most commonly installed in engines that have been modified for increased horsepower, especially with turbocharging.

What does the 'H/W Turbo Tuff' designation mean?

The 'H/W Turbo Tuff' designation typically indicates that these rods are a Heavyweight option, specifically intended for turbocharged applications where increased durability and strength are paramount to handle the higher stresses.

About this part

Product Details

This set includes six Manley Performance Pro Series I-Beam connecting rods, crafted from 300M vacuum degassed steel alloy. These are a critical component for anyone looking to build a high-performance Nissan GT-R VR38DETT engine, especially when dealing with significant power increases from turbocharging. They are designed to handle the stresses that come with boosted applications, ensuring reliability where stock components might falter.

Manley has a strong reputation for building robust engine internals, and these Pro Series rods are a prime example. The 300M alloy is known for its exceptional strength and fatigue resistance, making it a popular choice for serious performance builds. The I-beam design offers a good balance of strength and weight, and Manley offers various weight options within their Pro Series line to match your specific engine build needs, whether you're aiming for lighter rotating assembly for quicker response or a heavier setup for extreme durability. Some rods in this Pro Series range also carry NHRA Legal certification for specific racing classes, indicating their suitability for demanding competition environments.

When building a VR38DETT for serious power, upgrading the connecting rods is a fundamental step. These Manley rods are built to withstand the increased cylinder pressures and forces generated by turbocharging and aggressive tuning. Ensure you have the correct supporting components and follow proper assembly procedures when installing these high-performance parts to achieve the best results.
