Tomei 144.20mm STD Forged H-Beam Connecting Rod Set TA203A-NS04A for Performance Engines - TA203A-NS04A

If you're diving into the world of tuning your Nissan 350Z, you'll want to check out the Tomei Forged H-Beam Connecting Rod Set. These rods are specifically made for the VQ35DE engine and come in at a solid 144.20mm in length. Trust me, if you're looking to beef up your engine's durability and overall performance, this is a worthwhile upgrade.

Now, let's talk about what makes these rods stand out. They're forged, which means they're not just lightweight but also built to handle the kind of stress you might throw at them on the track or during spirited drives. The big end is designed with a slant that enhances rigidity, so you can push your engine without worrying about it falling apart. Plus, the rib-shaped cap and large diameter dowel add even more strength where it counts.

But it's not just about strength; it's also about smart engineering. The oil supply to the small end comes through two ports, which helps keep everything well-lubricated, especially under high RPMs. And those ARP L19 bolts? They're high strength and designed to keep everything locked down tight, so you can focus on enjoying the drive instead of worrying about your internals.

  • Lightweight, high rigidity forged design
