When powering high-draw accessories such as aftermarket audio amplifiers, auxiliary cooling fans, or upgraded lighting, the stock stator windings saturate quickly, leading to extreme thermal stress. This amperage deficit causes severe voltage drop down to sub-12.5V levels at idle, inducing headlight flicker, erratic idle control, ignition coil performance degradation, and accelerated battery sulfation. Over time, heat soak degrades the factory internal diode pack, resulting in total charging failure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered around heavy-gauge copper stator windings and a precision dynamic-balanced rotor, this 185-amp direct-replacement unit delivers continuous, high-efficiency current across the entire RPM band. It integrates a heavy-duty solid-state internal voltage regulator to clamp charging voltage between 13.5V and 14.5V, mitigating transient spikes. High-temperature sealed bearings reduce rotational friction and mechanical drag on the accessory belt drive. Operating within factory mounting geometry, it retains the OEM rotation, pulley offset, and terminal harness plug for clean installation while replacing parts like \u003cstrong\u003e23100-4M611\u003c\/strong\u003e and \u003cstrong\u003eAL2390X\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 High Output Alternator (185 Amp, 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% style=\" border-collapse: collapse border: solid font-size: min-width:\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;\"\u003e1999-2002 Infiniti G20\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;\"\u003eSR20DE \/ P11\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;\"\u003e140 hp \/ 132 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;\"\u003eAL2390X, 210-4164, A2TB3891, A2TB4691, 23100-4M611, 23100-4M610, 23100-9F511, 13784\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\u003e1999 Infiniti G20 Base 2.0L L4 (SR20DE)\u003c\/li\u003e\n  \u003cli\u003e1999 Infiniti G20 Touring 2.0L L4 (SR20DE)\u003c\/li\u003e\n  \u003cli\u003e2000 Infiniti G20 Base 2.0L L4 (SR20DE)\u003c\/li\u003e\n  \u003cli\u003e2000 Infiniti G20 Touring 2.0L L4 (SR20DE)\u003c\/li\u003e\n  \u003cli\u003e2001 Infiniti G20 Base 2.0L L4 (SR20DE)\u003c\/li\u003e\n  \u003cli\u003e2001 Infiniti G20 Touring 2.0L L4 (SR20DE)\u003c\/li\u003e\n  \u003cli\u003e2002 Infiniti G20 Base 2.0L L4 (SR20DE)\u003c\/li\u003e\n  \u003cli\u003e2002 Infiniti G20 Sport 2.0L L4 (SR20DE)\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 P11 G20?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1999-2002 Infiniti G20 equipped with the \u003cstrong\u003eSR20DE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my charging wiring for this alternator?\u003c\/h4\u003e\n\u003cp\u003eWhile it plugs directly into the factory harness, upgrading the main B+ charging cable and chassis ground wires (Big 3 upgrade) is recommended to safely handle the maximum 185-amp current flow.\u003c\/p\u003e\n\n\u003ch3\u003eThe Infiniti Tuner Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to meet the rigorous demands of classic JDM touring platforms, this alternator maintains peak current delivery to preserve ignition voltage stability and clean throttle response under high parasitic loads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67898843726072,"sku":"DS-EYZSZ701Z","price":319.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-infiniti-g20-1999-2002-2-0l-1.jpg?v=1793328744","url":"https:\/\/performancechiptuning.com\/es\/products\/high-output-alternator-for-infiniti-g20-1999-2002-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
