If you're deep into the RB26 scene, you've probably heard of Tomei. They've been around the block, and their new ARMS Mx8260 Turbocharger is a solid piece of engineering that builds on their M-Series legacy. This turbo isn't just a shiny upgrade; it's got some serious tech behind it that makes it a must-have for anyone looking to push their RB26DETT to new heights.

First off, let's talk power. This turbo can handle up to 650HP, which means it's built for those who want to really crank up the boost and feel the rush. It's designed specifically for the RB26 powertrain, so you know it's going to fit like a glove in your Nissan. Compared to the Mx7655, the Mx8260 shines in the higher RPM range, giving you that extra kick when you need it most. If you're after a turbo that pulls hard at the top end, this is it.

One of the standout features is the multi-rate billet actuator. It's built tough with a forged construction and comes with six springs. This means you can mix and match up to three springs to dial in your boost just right. Plus, the swivel nipple design makes hose routing a breeze—no more wrestling with tight spaces.

Now, let's get into the compressor wheel. This isn't your typical cast wheel; it's a lightweight billet piece made from aerospace-grade materials. The thinner blades and larger surface area mean better airflow and quicker spool times. You'll notice the difference when you step on the gas.
