So, you've probably heard of Tomei, right? They've been in the game since 1968, tuning race cars in Japan and really getting their hands dirty in the world of motorsports. Over the decades, they've become a big name, especially with how they've pushed the envelope in automotive research and racing culture. If you're looking for parts that have seen action in just about every motorsport you can think of, you're in the right place.

When it comes to crankshafts, the Tomei 2.2 91.0mm Full Counterweight Stroker is a beast. This isn't just some factory crank that's been slapped together. Nope, this bad boy is designed with racing in mind. The crankshaft is the heart of your engine, taking all that torque from the pistons and connecting rods and channeling it to the wheels. It's under constant stress, especially when you're pushing your engine to its limits on the track or during spirited drives. You can feel the difference when you're flooring it and then suddenly backing off; that's a lot of twisting forces at play, and you need something that can handle it.

Most factory crankshafts are built to save a few bucks, which means they're not exactly optimized for high-performance driving. They're made to survive stop-and-go traffic, not the intense demands of racing. That's where Tomei steps in. Their crankshafts are forged or made from solid billet steel, giving you that extra strength where you need it most. Forging creates a stronger grain structure, so you know this crankshaft is built to last. Plus, every Tomei crank is machined and balanced to perfection, which means less vibration and wear on your engine.

Let's talk specs: this crankshaft weighs in at 18kg and has a stroke of 91.0mm, making it a solid choice for those looking to upgrade their Nissan SR20DET. It's compatible with a bunch of models too, including the Nissan 15 Silvia (1999-2002), the Nissan 180SX (1989-1999), and the Nissan Silvia S14 (1993-1998), just to name a few. If you want to dive deeper into the installation process, you can find the instructions here.

In short, if you're serious about performance and want a crankshaft that can take the heat, the Tomei crankshaft is a solid investment. It's not just a part; it's a piece of racing heritage that you can trust to keep your engine running strong.
