If you're looking to give your Subaru a serious boost, the Tomei ARMS Mx8265 Turbocharger is worth your attention. This isn't just another turbocharger; it's an evolution of Tomei's original M-Series design, and they've really nailed it with some impressive upgrades. The new lightweight billet wheel and multi-rate billet actuator make a noticeable difference in performance, and the ARMS technology that Tomei is famous for is front and center here.

Now, let's get into the details. This turbocharger kit is designed for the EJ20 and EJ25 engines and can handle up to 450 horsepower. That's right—450! With that kind of power, you can really feel the difference when you hit the gas. The multi-range billet actuator is a game-changer too. It's built tough with a reinforced forged billet construction and comes with six springs for fine-tuning your boost. You can mix and match up to three springs to dial in the perfect setup for your needs. Plus, the swivel type nipple gives you more flexibility when routing your hoses, which is always a plus in tight engine bays.

The real star of the show might just be the newly designed billet compressor wheel. Unlike traditional cast wheels, this one is made from aerospace-grade materials, making it not only durable but also lightweight. The thinner blades and larger surface area significantly improve airflow, which means quicker spool times and a more responsive throttle. You'll notice the difference when you're merging onto the highway or taking those corners a little faster.
