Tomei ARMS M8265 Turbo for Subaru STI/WRX EJ20/25

The ARMS M8265 is the largest bolt-on turbo possible that the engineers can fit into the limited space of the EJ engine. Despite the size, the internals of the turbocharger speaks other wise; extracting the most and finest efficiency from its design. The end result is a turbo that maintains the best characteristics of the EJ engine with the added benefit of an extended power band to the high RPM region. The crucial step in tuning the EJ is the turbocharger upgrade where the increase in overall performance can be acquired.
