Classic Retrofit's upgraded 240A alternator for classic Porsche 964 and 993 models.  A serpentine belt with a tensioner is recommended when installing this unit.  For standard double pulley and RS pulley arrangements we recommend the 175A unit.  

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.
