2013–2016 Scion FR-S, 2013–2020 Subaru BRZ, 2017–2020 Toyota 86, 2022–2026 Toyota GR86 & Subaru BRZ 2.4L

Part #: PSP-ENG-113BL

Overview

The Perrin Water Pump Pulley is a precision-engineered performance upgrade designed specifically for the Toyota GR86 and Subaru BRZ 2.4L engines from 2013 through 2026 model years, including the Scion FR-S and Toyota 86. This lightweight pulley replaces the heavier OEM component to reduce rotational mass on your engine’s accessory drive system. By decreasing the weight of the water pump pulley, the engine experiences less parasitic drag, allowing for improved throttle response and a slight increase in available power.

Ideal for enthusiasts seeking a simple yet effective way to enhance engine efficiency and responsiveness, the Perrin Water Pump Pulley delivers tangible performance benefits without requiring complex modifications or tuning. Its anodized blue finish also adds a clean, high-quality aesthetic under the hood.

Construction & Design

The Perrin Water Pump Pulley is crafted from premium 6061-T6 billet aluminum, a material known for its excellent strength-to-weight ratio and resistance to fatigue. This ensures the pulley can withstand the rigors of daily driving and spirited performance use without compromising durability. The pulley is CNC-machined with tight tolerances to match OEM dimensions, guaranteeing seamless integration with the factory water pump and belt system.

The anodized blue finish not only provides corrosion resistance but also adds a distinctive visual upgrade to the engine bay. This combination of lightweight construction and robust design results in a component that enhances performance while maintaining long-term reliability.

Performance & Sound

By reducing the weight of the rotating water pump pulley, this upgrade decreases parasitic drag on the engine’s accessory drive system. This reduction in rotational mass allows the engine to rev more freely, improving throttle response and potentially increasing overall power delivery. While the pulley does not directly alter engine sound, the improved responsiveness can contribute to a more engaging driving experience.

Installation & Fitment

Installation of the Perrin Water Pump Pulley is straightforward and designed to be a direct replacement for the factory pulley. It requires no special tools beyond standard hand tools and can typically be completed in under an hour. The pulley fits perfectly on the water pump shaft of the specified Toyota and Subaru models without any modifications or adjustments.

It is compatible with the following vehicles:

• 2013–2016 Scion FR-S
• 2013–2020 Subaru BRZ (2.0L)
• 2017–2020 Toyota 86 (2.0L)
• 2022–2026 Toyota GR86 (2.4L)
