If you're serious about performance, you've probably heard of Tomei. They've been in the game since 1968, starting out as a race car tuner in Japan. Over the decades, they've really cemented their reputation in the automotive world, especially in motorsports. When you're pushing an engine to its limits, you need parts that can take the heat—and that's where Tomei shines.
Let's talk about their crankshaft, specifically designed for the Toyota 4A-G(Z) engines. This isn't just any crankshaft; it's a beast built for serious driving. Weighing in at 11.5 kg and measuring 83 mm, it's crafted from high-quality forged steel. Forging gives it a tougher grain structure compared to cast pieces, meaning it can handle the intense forces that come with racing. If you're looking to up your game, you want something that can withstand the stress of high RPMs and quick throttle transitions without breaking a sweat.
Now, I know what you're thinking—what's the real deal with all that torque? Well, the crankshaft is the heart of your engine. It connects the pistons and connecting rods, turning all that power into motion. The factory crankshafts are decent for everyday driving, but they're built with cost-cutting in mind. Tomei, on the other hand, has engineered this crankshaft to be reliable under racing conditions. It's machined and balanced to prevent vibrations that can lead to premature wear. You want your engine running smooth, right?
Here's a quick rundown of the specs:
- Crank Pin: 42 mm
- Main Journal: 48 mm
And it fits a range of Toyota models, including:
- Toyota AW11 MR2 (1984-1989)
- Toyota 92 Levin/Trueno (1987-1991)
- Toyota 86 Levin/Trueno (1983-1985)
- Toyota 101 Levin/Trueno (1991-1995)
- Toyota 111 Levin/Trueno
For those who like to get hands-on, you can find the install instructions right here. If you're ready to take your build to the next level, this Tomei crankshaft is a solid choice. It's designed for the serious enthusiast who knows that every little detail counts when it comes to performance.
