93-95 RX-7 (11mm) | ID1300-XDS | Injector Dynamics | 1300.11.03.60.11.2
ID1300-XDS, for 93-95 RX-7, Requires Top Feed Conversion. 11mm (blue) adapters. -204 / 14mm lower o-rings. Set of 2.
The ID1300 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 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 was designed with an eye towards ethanol fueled engines, we have accounted for the occasional need to convert back to gasoline. The ID1300 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 allows fitment in 200+ applications, making it the most versatile injector in our lineup. The 1300 has continued to be refined and improved over the years, and the 1300-XDS is the latest and best version to date.

Frequently Asked Questions About the 93-95 RX-7 (11mm) | ID1300-XDS
Is the ID1300-XDS set suitable as the only primary injector upgrade, or is it better paired with secondary injectors for high-boost FD3S E85 conversions?
This set is specifically sized for use as primary injectors on the twin-turboFD3S 13B-REW. At 1335 cc/min each, they handle light load and low RPM fueling with superior fidelity. For full E85 conversion on a non-sequential or single-turbo FD targeting over 450 whp, they are designed to be paired with high-flow secondary injectors (e.g., ID1700-XDS or ID2600-XDS) to meet the extreme fuel demands of the 13B-REW at high boost.
What is the 11mm designation for this part number, and is this ID1300-XDS (PN: 1300.11.03.60.11.2) a drop-in fit for the FD3S primary rail?
The 11mm refers to the inner diameter of the adapter top that seals to the factory FD primary fuel rail. This set features an 11mm top adapter and a 14mm lower O-ring (with the -204 cushion) to achieve the necessary 60mm O-ring to O-ring length. This configuration is a direct fit for the factory primary rail bores with no spacers required.
I'm tuning my FD3S with a Haltech or MicroTech ECU. Do Injector Dynamics provide the Short Pulse Adder data for the 1300-XDS?
Yes. Injector Dynamics provides comprehensive characterization data, including the necessary Short Pulse Adder tables. This data is critical for rotary tuners using standalone systems like Haltech or MoTeC to ensure accurate fuel control in the non-linear range, which is especially important for maintaining a stable idle on the 13B rotary engine.
Will I need separate Denso to USCAR wiring adapters for both the primary and secondary injectors on my RX-7 FD3S?
The ID1300-XDS uses the USCAR connector, while the stock FD3S wiring uses Denso connectors for both primary and secondary banks. You will need a total of four USCAR to Denso Plug-and-Play (PNP) adapters (ID P/N 90.3) if you are upgrading all four injectors to the ID-XDS series and want a crimp-free installation.
Does the ID1300-XDS offer improved spray atomization compared to the stock $FD3S primary injectors to help prevent rotor face wash?
Yes. The ID1300-XDS features a superior spray pattern and atomization compared to vintage stock injectors. This improved atomization ensures the fuel is more evenly mixed with air before entering the combustion chamber, which is vital for preventing fuel wash and promoting more complete combustion, ultimately improving engine longevity and stability under high load.
