P2M OEM-Spec Replacement Alternator – Nissan R32 Skyline | RB20DET / RB26DETT (BNR32) | 80A | New Core & Internals

Restore reliable charging system performance to your Nissan R32 Skyline with the P2M OEM-Spec Replacement Alternator — a direct bolt-on alternator replacement engineered to OEM specifications for the R32 Skyline with the RB20DET (non-GT-R) and RB26DETT (BNR32 GT-R) engines. Built with a new core and new internals — not a remanufactured or rebuilt unit — the P2M alternator delivers OEM-spec 80A output and direct bolt-on fitment with no modifications required.

Key Features

• OEM-Spec 80A Output – Factory Charging Performance: 80 amp output matches the factory R32 Skyline alternator specification — correct charging system performance for stock and mildly modified RB20DET and RB26DETT builds. For heavily modified builds with significantly increased electrical loads (high-output ignition, large fuel pumps, additional lighting), verify that 80A output is sufficient for your specific build's electrical demand
• New Core & New Internals – Not Remanufactured: Built with a new core and new internal components — not a remanufactured, rebuilt, or refurbished unit. New construction means no worn brushes, no degraded windings, and no uncertainty about the condition of internal components — a meaningful advantage over rebuilt alternators for a vehicle as aged as the R32 Skyline
• Direct Bolt-On – No Modifications Required: Direct bolt-on replacement for the factory R32 Skyline alternator — uses the factory mounting points and electrical connector. No modifications, no adapter brackets, no wiring changes required
• RB20DET & RB26DETT Compatible: Fits both the RB20DET (standard R32 Skyline GTS/GTS-T) and the RB26DETT (BNR32 GT-R) — verify your specific R32 variant and engine before ordering
• P2M Quality: Manufactured by P2M (Phase 2 Motortrend) — a respected aftermarket brand known for quality replacement and performance parts for Japanese domestic and enthusiast vehicles
