170 amp high output racing alternator for Toyota Supra 1JZ 2JZ

The MechMan 6 phase hairpin high output alternator for Toyota Supra 2JZ offers a solution to the inadequate alternator that comes from the factory on these vehicles. This unit features twin rectifiers with (12) massive press fit diodes, as compared to the small (8) diode rectifier in the stock alternator. Even mild performance builds will typically consume more amperage than what the stock Supra alternator can provide. Hairpin stator technology provides better high RPM durability, and better resistance to heat from the turbo manifold. This unit uses a high RPM friendly larger diameter pulley, and bolts directly in place of the OEM alternator. NOTE: A 4 gauge or larger positive and negative cable needs to be run between the alternator and the battery terminals for proper function.
