Classic Retrofit's upgraded high-output alternator for classic Porsche 964 and 993 models has been tested at over 145A* on the standard 964/993 pulley and belt. With a simple installation process, this UK-manufactured upgrade is the highest output alternator available for your Porsche 964/993. The idle output is in excess of 100A!
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.
*The alternator peak output is 240A. Beyond 145A, a serpentine belt will be required.
