ID1300-XDS, for 89-92 RX-7 (incl. Turbo II). 14mm (purple) adapter top. -204 / 14mm lower o-rings. Set of 2.

The ID1300-XDS is an all-new injector, designed in partnership with Bosch Motorsport. This collaboration has given us the ability to design a high-flow injector with characteristics specific to the needs of the motorsport tuner. The ID1300-XDS was designed with alternative fuels in mind and is the only performance injector available with all stainless internals. It is compatible with all known fuels and will stand up to the corrosive nature of alcohol better than any injector on the market.

While the ID1300-XDS was designed with an eye towards ethanol fueled engines, we have accounted for the occasional need to convert back to gasoline. The ID1300-XDS has a minimum fuel mass compatible with gasoline use, and will provide exceptional idle and cruise behavior under these conditions. In addition to its multi-fuel capabilities, the compact body of the ID1300-XDS allows fitment in 200+ applications, making it the most versatile injector in our lineup. The 1300-XDS has continued to be refined and improved over the years, and the 1300-XDS is the latest and best version to date.

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 89-92 RX-7 (14mm) ID1300-XDS Injectors

Which RX-7 models are compatible with the ID1300-XDS injectors?

The ID1300-XDS injectors are designed specifically for Mazda RX-7 models from 1989 to 1992. They provide precise fuel delivery for the 13B rotary engine, ensuring improved throttle response and support for performance upgrades.

What is the fuel flow rate of the ID1300-XDS injectors?

The ID1300-XDS injectors deliver a fuel flow rate of 1300cc/min at 3 bar of fuel pressure. This higher flow rate is ideal for tuned or turbocharged RX-7 engines that require more fuel for optimal performance.

Do I need to upgrade my fuel pump when installing these injectors?

For stock RX-7 engines, the stock fuel pump may suffice for moderate builds. However, for high-horsepower setups or heavy modifications, a high-flow fuel pump is recommended to maintain proper fuel pressure and injector performance.

Is ECU tuning required after installing ID1300-XDS injectors?

Yes, ECU tuning is essential when installing ID1300-XDS injectors. Proper tuning ensures correct fuel mapping, prevents engine issues, and maximizes both reliability and performance.

Are the ID1300-XDS injectors compatible with ethanol or high-octane fuels?

Yes, these injectors are fully compatible with ethanol blends and high-octane fuels. They maintain optimal spray patterns and consistent fuel delivery across various fuel types.
