S Series 6 Phase 170 amp Racing Alternator

The MECHMAN ALTERNATORS S Series 6 Phase 170 Amp Racing Alternator (MEC13546170) is a high-output electrical generator purpose-built for performance vehicles requiring sustained power delivery under demanding conditions. Engineered for the Toyota 2JZ engine platform and compatible with 1993–1998 Toyota Supra models, this 170-amp alternator delivers consistent electrical output for vehicles equipped with upgraded ignition systems, fuel injection controllers, and auxiliary lighting or accessory loads that exceed factory electrical capacity.

Rated at 170 amps at 12V, this racing alternator features a 6-rib serpentine pulley for compatibility with modern drive-belt configurations and a durable aluminum case that resists corrosion in high-heat engine bay environments. The 6-phase design optimizes rectification efficiency, reducing voltage ripple and heat generation during sustained high-RPM operation—critical for vehicles running tuned engines or frequent track sessions. At 14.3 lbs, the compact footprint (9.4 x 9.3 x 9.9 inches) allows straightforward integration into tight engine bay layouts while maintaining the electrical output margin required for fuel injection tuning, high-intensity HID or LED headlight systems, and auxiliary cooling fans.

This alternator addresses a core challenge in modified 2JZ platforms: stock electrical systems cannot sustain the amperage demands of tuned engines, particularly those running standalone engine management systems or aftermarket electrical accessories. Track-focused builders, drift competitors, and street performance enthusiasts select 170-amp alternators to eliminate voltage sag during acceleration and ensure stable charging across the full RPM range. The racing-grade construction and high-output capacity make this unit suitable for any 2JZ application where reliability and sustained power delivery are non-negotiable.
