Over decades of heat soak, factory Paris-Rhone internal diodes break down, brush packs wear unevenly, and slip rings score. This thermal fatigue causes severe voltage drops at idle, slow hot restarts, ignition cutouts under boost, and chronic battery undercharging across the \u003cstrong\u003eType 930\u003c\/strong\u003e electrical harness.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis remanufactured unit utilizes upgraded internal components designed to withstand harsh air-cooled operating temperatures. Built on the original Paris-Rhone architecture, it features a heavy-duty balanced rotor, heavy copper stator windings, and a solid-state internal voltage regulator rated for a steady 75-amp output. It restores factory electrical tolerances for the Bosch K-Jetronic fuel injection and CDI ignition systems without requiring wire splices, bracket spacers, or pulley alignment modifications, directly superseding OEM reference \u003cstrong\u003e911-603-120-04\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Remanufactured 75-Amp Alternator (Internal Regulator)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100 Mich\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1978-1979 Porsche 930\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eType 930\/60 3.3L Turbo \/ 930 Chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e261 hp \/ 291 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e911-603-120-04\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1978-1979 Porsche 930 Turbo 3.3L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the 930 chassis?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1978-1979 Porsche 930 equipped with the \u003cstrong\u003eType 930\u003c\/strong\u003e 3.3L Turbo engine.\u003c\/p\u003e\n\n\u003ch4\u003eShould I bench test or replace the battery when installing this alternator?\u003c\/h4\u003e\n\u003cp\u003eYes, ensure the battery and ground straps are fully tested and charged prior to startup to prevent immediate thermal overload on the new internal regulator.\u003c\/p\u003e\n\n\u003ch3\u003eThe Porsche Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to precise European standards, this unit drops straight into the factory air cooling shroud to deliver dependable system amperage and stable voltage regulation with zero electrical interference or modification.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67621552161016,"sku":"DS-E0HT7K05L","price":438.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/alternator-for-porsche-930-1978-1979-3-3l-1.jpg?v=1791664586","url":"https:\/\/performancechiptuning.com\/fr\/products\/alternator-for-porsche-930-1978-1979-3-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
