Injector Dynamics ID2600-XDS Fuel Injectors | Single Injector | 48mm, 11mm Adapter Top, Subaru WRX Lower (2600.48.11.WRX)

Chasing lean spikes at high boost? Your injectors are the weak link.

A factory fuel system that was sized for stock power runs out of injector long before a built engine runs out of airflow. The ID2600-XDS answers that with 2600cc/min of flow at 3.0 bar, compatibility with methanol, ethanol, and all known hydrocarbon fuels, delivered as a single injector in the 48mm body, 11mm adapter top, WRX-16B bottom adapter configuration. It is backed by full characterization data, so your ECU gets real numbers, not estimates. Fueling you can build a tune on.

What You'll Feel

• Headroom to grow the build without touching the fuel system again
• Confidence to run ethanol daily without worrying what it is doing to your injectors
• Faster dyno sessions, because accurate injector data means less time chasing fuel trims
• Crisp part-throttle response instead of the surge and stumble big injectors are known for
• Stock-like idle and clean cold starts, even at this injector size

Features

• Nominal flow rate: 2600cc/min at 3.0 bar (43.5 psi)
• Maximum differential fuel pressure: 9.0 bar (130.5 psi), requires a minimum of 11 volts
• Compatible with methanol, ethanol, and all known hydrocarbon fuels
• Not compatible with ethers (MTBE, ETBE, TAME) or nitromethane
• USCAR electrical connector
• Configuration: 48mm body, 11mm adapter top, WRX-16B bottom adapter
• Sold individually, so you can replace one injector or build a set for an uncommon cylinder count

The Details

The ID2600-XDS is the highest flow injector Bosch offers and flows 50 percent more than the ID1700x. It was developed specifically for liquid fuels, with corrosion resistant internals for long term ethanol and methanol use. Dual Slope Matching is the difference maker here: matched on static flow alone, injectors this size deviate around plus or minus 5.1 percent at low pulse widths, while Dual Slope Matching brings that down to plus or minus 1.4 percent. One thing to know going in: it needs a minimum of 11 volts and is not compatible with ethers like MTBE or with nitromethane. Injector Dynamics publishes full characterization data, including slope, offset (dead time) versus voltage and pressure, and short pulse width behavior, so your tuner can load real numbers instead of chasing fuel trims across the map. Accurate dead times are what make large injectors behave at idle and cruise, and they are the reason these tune quickly and stay tuned. This configuration uses machined top adapters (already fitted) to suit the rail height listed above. The WRX-16B bottom adapter (already fitted) seats these in the 16mm Subaru manifold bore. If your harness does not have USCAR plugs, plug and play connector adapters are available separately, no cutting or soldering required.
