The Tomei M8265 turbocharger has the potential to deliver 450hp with the stock layout; from 4000RPM upwards is where peak power comes in. This Turbo's special characteristics will really show when added engine tuning and internal upgrades are done. The initial spool characteristics are just right, with a seamless linear power curve that matches the engines RPM with the power output. This gives the best drivability results.

With the stock displacement, you can expect to see good power around the 5500rpm mark and higher. But with the increase in the engines displacement, even more potential gains are possible. The M8265 will deliver and unleash your engines full potential.

The ARMS series turbo kits all come supplied with all the required gaskets and fitting accessories for a true bolt on application out of the box. This turbo can be installed immediately without the need to hunt for other parts and comes with a 1-Year limited warranty after registration with Tomei.
