Mechman 240 amp high output alternator for Toyota Supra 2JZ 1JZ - BLACK

Supercharge Your Supra’s Charging System.

The factory Toyota Supra 2JZ alternator is notoriously weak—and if you’ve added even mild performance upgrades, you’re already outrunning your stock power supply. Step up to the MechMan 240-Amp Alternator, the ultimate charging solution engineered specifically for high-performance 2JZ builds.

While the OEM unit chokes on a small 8-diode setup, the MechMan powerhouse features twin rectifiers packed with 12 massive, press-fit diodes to deliver rock-solid, uninterrupted amperage. Built to thrive in brutal environments, its advanced Hairpin stator technology ensures elite high-RPM durability and maximum resistance to intense turbo manifold heat.

Best of all? It’s a direct bolt-on replacement—no custom fabrication required.
