Titan Motorsports 240 amp S series racing alternator for Toyota 2JZ

240 amp High Output S series alternator for Toyota Supra This premium quality unit features twin rectifier plates, 12 huge heavy duty diodes, and hairpin stator construction for un-matched low RPM output and durability. Suitable for both the Turbocharged and Naturally aspirated versions of the Toyota 2JZ engine, these alternators will run cooler, maintain better voltage, and last longer than the original 3 phase round-wire Toyota alternator design. Installation is a direct bolt in, but a 1 inch shorter than stock length belt (not included) will be required for proper belt tension. This unit accepts the factory Toyota Supra alternator harness, and will provide 140 amps @ 800 engine RPM with the included 46mm alternator pulley. S series units are built in the USA with OEM Toyota / Lexus internal components
