In the thermally demanding rotary engine bay of the \u003cstrong\u003eFC3S\u003c\/strong\u003e, stock internal diodes and brush assemblies degrade rapidly from chronic heat soak. Compounding the issue, the OEM unit suffers severe voltage drop at idle, starving critical systems when running modern electric radiator fans, auxiliary fuel pumps essential for the \u003cstrong\u003e13B\u003c\/strong\u003e engine, or aftermarket audio amplifiers.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 130-amp heavy-duty alternator resolves low-voltage idle sag through high-efficiency, heavy-gauge copper stator windings that generate robust amperage across low and high engine speeds. A precision-balanced rotor prevents high-RPM vibration harmonics typical of high-revving rotary engines, while premium double-sealed bearings resist heat-induced bearing failure. Regulated by an upgraded internal solid-state voltage regulator, it delivers a steady 13.5V to 14.5V output directly through OEM-spec mounting lugs and factory-keyed harness terminals.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x 130-Amp High Output Alternator (Part # \u003cstrong\u003e14910\u003c\/strong\u003e)\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%\" 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;\"\u003e1986-1988 Mazda RX-7\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;\"\u003e13B Rotary \/ FC (Series 4)\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;\"\u003e146 hp \/ 138 lb-ft (Naturally Aspirated)\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;\"\u003e210-4263, N326-18-300, A2T47474, 14910\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\u003e1986-1988 Mazda RX-7 Base 1.3L Rotary\u003c\/li\u003e\n  \u003cli\u003e1986-1988 Mazda RX-7 GXL 1.3L Rotary\u003c\/li\u003e\n  \u003cli\u003e1986-1987 Mazda RX-7 Sport 1.3L Rotary\u003c\/li\u003e\n  \u003cli\u003e1987-1988 Mazda RX-7 Turbo II 1.3L Rotary Turbo\u003c\/li\u003e\n  \u003cli\u003e1988 Mazda RX-7 GTU \/ Convertible 1.3L Rotary\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 FC RX-7?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-in fit for the 1986-1988 Mazda RX-7 equipped with the \u003cstrong\u003e13B\u003c\/strong\u003e rotary engine, retaining factory mounting points and plug connections.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my wiring for this alternator?\u003c\/h4\u003e\n\u003cp\u003eWhile this unit functions with the OEM harness, installing an upgraded heavy-gauge main B+ charge wire and ground cables is strongly recommended to maximize current transfer and prevent resistance bottlenecks.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mazda Rotary Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet the relentless demands of high-revving rotary powerplants, this charging solution delivers uncompromising voltage stability to keep your apex seals lubricated, fuel delivery constant, and ignition firing clean.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67898749288696,"sku":"DS-EJUL6K0CN","price":371.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-mazda-rx-7-1986-1988-1-3l-1.jpg?v=1793327055","url":"https:\/\/performancechiptuning.com\/de\/products\/high-output-alternator-for-mazda-rx-7-1986-1988-1-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
