Product Description

The Garrett 781328-0002 Speed Sensor Pro Kit is an accessory designed to measure and monitor turbocharger shaft speed on Garrett GT and GTX series turbochargers. By accurately tracking compressor wheel revolutions, the kit provides valuable data for tuners and engine builders - helping to validate turbo performance, optimize tuning, and avoid overspeed conditions that can lead to premature turbo failure.

This **universal accessory** is not vehicle-specific; it is intended for use with compatible GT and GTX turbos during custom builds, performance tuning sessions, or data logging applications. The Pro version includes the speed sensor and necessary wiring but does not include a display gauge - making it ideal for integration with external data loggers, aftermarket engine management systems, or specialized performance dashboards. Installation requires access to the turbo compressor housing and basic wiring connections to power and logging equipment.
