Grams Performance Fuel Injectors

2013–2021 Scion FR-S, Subaru BRZ, Toyota 86 1600cc

G2-1600-1201

Overview:

The Grams Performance 1600cc Injector Kit is engineered specifically for the Scion FR-S, Subaru BRZ, and Toyota 86, delivering precise fuel delivery for enhanced engine performance. Designed for enthusiasts and tuners seeking reliable and consistent fueling upgrades, these injectors support high-performance applications while maintaining smooth drivability. Whether you are upgrading your engine for forced induction or high-flow naturally aspirated setups, this injector kit ensures accurate fuel metering to maximize power and response.

Each injector is flow matched and dynamically balanced to within one percent of each other, providing exceptional cylinder-to-cylinder consistency. This results in improved idle quality, throttle response, and overall engine efficiency, even at low pulse widths. Compatible with a wide range of fuels, including oxygenated blends and race fuels, the Grams Performance injectors offer versatility for various tuning needs.

Key Features:

Grams Performance injectors incorporate advanced technology and premium materials to meet the demands of modern performance engines. Key features include:

• High-impedance design optimized for high-performance applications
• Stainless steel internal components for durability and corrosion resistance
• Compatible with all fuels including oxygenated fuels such as MTBE, FTW, Q16, M5, and C45
• Ultra-fast solenoids providing precise and linear fuel metering across a wide operating range
• Individually flow tested and dynamically matched for consistent fuel delivery
• Maintains optimal idle quality and engine response even at very low pulse widths
• Designed to operate reliably at high fuel pressures common in forced induction setups
• Improves cylinder-to-cylinder fuel consistency for smoother engine operation

Construction & Design:

The Grams Performance 1600cc injectors are built with premium stainless steel internals that resist wear and corrosion, ensuring long-lasting performance under demanding conditions. The advanced manufacturing process includes stringent quality control and individual flow testing to guarantee each injector meets exacting standards. The high-impedance coil design reduces electrical noise and improves compatibility with factory and aftermarket engine management systems.

These injectors feature ultra-fast solenoids that deliver a linear response curve, allowing precise fuel atomization and metering even at the shortest pulse widths. This precision supports smooth idle, improved throttle response, and consistent power delivery across the entire RPM range.

Installation & Fitment:

The injector kit is a direct fit for the Scion FR-S, Subaru BRZ, and Toyota 86 models from 2013 through 2021, requiring no modifications for installation. Installation involves removing the factory injectors and replacing them with the Grams Performance units, maintaining OEM connectors and fuel rail compatibility. Proper tuning is recommended to optimize fuel maps and take full advantage of the increased injector flow capacity.

What's Included:

• Set of four Grams Performance 1600cc fuel injectors
• Installation instructions

Ideal For:

This injector kit is ideal for enthusiasts upgrading their naturally aspirated or forced induction Scion FR-S, Subaru BRZ, or Toyota 86 engines who require reliable, high-flow fuel delivery. It suits those running ethanol blends, race fuels, or high-octane pump gas and looking to improve engine response, power consistency, and tuning flexibility.

Grams Performance focuses on fueling and air/fuel support parts for high-output builds, offering components like fuel pumps, filters, and throttle-body solutions aimed at stable, consistent fuel delivery. It’s a solid choice for turbo/supercharged or ethanol builds where clean fueling and reliability are just as important as peak horsepower.
