If you're diving into the world of Mitsubishi Evolutions, you've probably heard of the Tomei 147mm Forged H-Beam Connecting Rod Set. This isn't just another aftermarket part; it's a serious upgrade for anyone looking to boost the performance of their 4G63 engine in Evo models 1 through 9. I've had my hands on these rods, and let me tell you, they're built with precision and strength that you can really feel when you hit the throttle.
These connecting rods are forged, which means they can take a beating while maintaining their integrity. That's crucial for anyone pushing their engine to the limit. The lightweight design doesn't just help with performance; it also improves rigidity, especially in the big end, thanks to a clever slant design. You'll notice the difference when you're revving hard or tackling those tight corners.
One of the standout features is the rib-shaped cap that adds even more strength without adding unnecessary weight. Plus, the large diameter dowel and dual oil ports for the small end ensure that everything stays well-lubricated, so you can focus on enjoying the ride without worrying about your engine overheating.
Now, let's talk specs. These rods are made from SNCM43 material, which is known for its durability. They come equipped with high-strength ARP L19 bolts—trust me, these aren't going to snap on you. The dimensions are spot on too: a center-to-center measurement of 147mm with a big end bore of 48.0mm by 26mm. If you're into the nitty-gritty, the small end bore measures 22.0mm by 23mm, and the whole setup weighs in at 630 grams. Just make sure you have the right setup, as they're designed specifically for the 4G63 engine in the Evo from 1992 to 2007.
If you're looking to install these bad boys, you can find the instructions here. Trust me, getting these in will be worth every minute you spend in the garage.
In a nutshell, if you're serious about squeezing every bit of power out of your Evo, these Tomei connecting rods are a solid choice. They're reliable, durable, and will definitely up your game on the track or the street.
