    Does anyone know if I can install the 130w or 150w alternator in my Tundra which came with the 100w alternator. The 150w is installed on the Tundras with the tow package. I believe that my alternator has gone out and I may want to install the tow package at a later time.
    Thanks,

    Some Mods :) See build thread for details
    If it's an option with the Tundras with the tow package then it should work as an upgrade on yours

    One little thing, it's amps, not watts that alternators are rated in. Just to save some confusion when you go to buy one. FWIW, 150A amps at 12V = 1800Watts

    Just remember PIE. P=I*E. Power equals current (I) times voltage (E).
