G20 91-02 (14mm) | ID2600-XDS | Injector Dynamics | 2600.60.14.14.4
ID2600-XDS, for G20 / FWD SR20 applications. Must be converted to top-feed. 14mm (purple) adapter. Set of 4.
The ID2600-XDS is the most recent offering from the partnership of Injector Dynamics and Bosch Motorsport.
The ID2600-XDS was developed specifically for use with liquid fuels, featuring corrosion resistant internals, and long term compatibility with ethanol and methanol.
The ID2600-XDS has the highest flow rate of any injector offered by Bosch, and flows 50% more than the ID1700x.
The ID2600-XDS benefits from Dual Slope Matching, a method of matching the flow rate in both the linear, and nonlinear operating range, providing better cylinder to cylinder consistency at low pulse widths.
Basic Specifications
- Nominal Flow Rate – 2600cc/min @ 3.0 Bar (43.5 psi)
- Maximum Differential Fuel Pressure – 9.0 Bar (130.5 psi) – Requires Minimum 11volt.
- Fuel Compatibility – Compatible with Methanol/Ethanol/All Known Hydrocarbons. NOT Compatible with Ethers (MTBE, ETBE, TAME) or Nitro Methane
- Electrical Connector – USCAR

What is Dual Slope Matching?
Dual Slope Matching is a method of matching injectors that provides the best possible cylinder to cylinder fueling across the entire operating range.
Traditionally, injectors were matched based on static flow rate alone, which resulted in large deviations at low pulse widths.
Injector Dynamics introduced Slope Intercept Matching over a decade ago, which provided even cylinder to cylinder fueling across the linear operating range of the injector.
With the progression of turbo technology, and increased use of alcohol fuels, greater demands are placed on fuel injectors, and they are often required to deliver fuel well outside of their linear operating range.
The concept of Dual Slope Matching extends the injector matching into the lower non linear operating range. Dual Slope Matching was conceived by Aaron Looft of Injector Dynamics, who was inspired by the dual slope injector characterization model used by Ford.

Frequently Asked Questions About the G20 91-02 (14mm) ID2600-XDS Injectors
Is the 14mm ID2600-XDS injector the correct choice for my G20 91–02 fuel rail?
Yes. The 14mm ID2600-XDS injectors are designed for G20 top-feed fuel rails that require the larger diameter. Always verify your fuel rail specifications to ensure proper fit and flow before ordering.
Does the 60mm injector body fit under the G20 stock fuel rail without modifications?
Yes. These injectors are built to the correct 60mm length with proper upper and lower O-rings, allowing direct installation in the OEM or compatible aftermarket top-feed fuel rail without spacers or adapters.
Where can tuners access official Injector Dynamics data for the G20 14mm injectors?
Injector Dynamics provides full characterization data, including flow rates, dead-times, and short pulse-width tables. This data is essential for ECU tuning to maintain accurate fueling and smooth drivability on the G20.
Are these 14mm injectors compatible with the G20 factory wiring harness?
Yes. The ID2600-XDS uses USCAR/EV14 connectors, and adapters are typically included for plug-and-play installation with the OEM harness, avoiding cutting or splicing.
How do these injectors maintain smooth idle and throttle response on modified or E85-fueled G20 engines?
Dual Slope Matching and precise low pulse-width control ensure smooth idle and consistent part-throttle fueling. Even with modifications, ethanol blends, or higher RPM use, these injectors maintain stable drivability and prevent lumpy idle.
