Classic Retrofit's upgraded 175A alternator for classic Porsche 964 and 993 models. This alternator is the best upgrade for cars with the standard double pulley or RS single pulley arrangements. The idle output is around 75A depending on pulley size and idle speed.
This is a brand new unit, not rewound or reconditioned and there is no core charge or exchange. Based on the large-case Denso 6 phase 'hairpin' alternator, the casing has been custom designed to fit all 964 and 993 fan housings. The alternator offers superior efficiency and produces less heat than the original units.
With so many electrical upgrades pushing old-school charging technology to the limit, Classic Retrofit's upgraded alternator for classic Porsche 911s is the perfect addition to a modern-day classic.
Used in conjunction with our electric A/C, this alternator offers higher levels of cooling without compromising battery voltage. All of our alternators come complete with heavy duty cables.
