NSX 91-96 | ID2600-XDS | Injector dynamics | 2600.60.11.14-O.6
ID2600-XDS, for 91-96 NSX / C Series, 11mm (blue) adapters. 14mm bottom o-ring, machine o-ring retainer to 11mm. Set of 6.
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 NSX 91-96 ID2600-XDS Injectors
Are the ID2600-XDS injectors suitable for naturally aspirated or lightly boosted C30A engines in a 91–96 NSX?
Yes. The ID2600-XDS injectors are designed to provide consistent and precise fuel delivery for the high-revving C30A V6. They can handle naturally aspirated builds efficiently and also provide ample capacity for mildly boosted setups, maintaining stable AFRs across the RPM range.
Does the 60mm injector body fit under the stock NSX fuel rail without modifications?
Yes. The 60mm long-body injectors with correct upper and lower O-rings are compatible with the NSX top-feed rail. They install directly without the need for spacers, adapters, or custom mounting brackets.
Where can tuners access the official Injector Dynamics calibration data for the NSX?
Injector Dynamics provides complete characterization data, including dead-times, short pulse width tables, and full flow curves. This data can be used with most standalone and ECU systems to ensure accurate fueling, smooth idle, and consistent performance at high RPM.
Are these injectors compatible with the NSX factory wiring harness?
Yes. The ID2600-XDS uses USCAR/EV14-style connectors. Adapters are typically included to allow plug-and-play installation with the NSX OEM harness, eliminating the need for splicing or electrical modifications.
How does the ID2600-XDS maintain smooth idle and drivability on a modified NSX?
Thanks to Dual Slope Matching and precise low pulse-width metering, the ID2600-XDS prevents idle stumble and roughness, ensuring smooth operation even on engines with aggressive cams, high RPM use, or ethanol blends.
