R32, R33, R34 GTR (14mm) | ID1300-XDS | Injector Dynamics | 1300.60.14.D.6
ID1300-XDS, for R32, R33, R34 / RB26. 14mm (purple) adapter tops. Denso lower. Set of 6.
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 ID1300-XDS Injectors for R32-R34 GTR
Why choose the 14mm top ID1300-XDS (PN: 1300.60.14.D.6) over the 11mm version for my RB26?
This 14mm top version is specifically designed for aftermarket billet fuel rails (like Radium or Plazmaman) that upgrade the RB26 fuel system and use the common 14mm injector bore. If your car has the stock fuel rail, you should order the 11mm version. Always confirm your rail size before ordering.
What maximum E85 horsepower will the ID1300-XDS set support on a twin-turbo RB26DETT GTR engine?
The ID1300-XDS (1335 cc/min at 43.5 psi) set of 6 injectors provides essential flow for GTR performance. It supports highly modified twin-turbo E85 setups well into the 800 to 1000+ wheel horsepower range, offering maximum fuel margin for aggressive GTR builds.
Does this USCAR ID1300-XDS set require PNP adapters to connect to the R32-R34 GTR factory harness?
Yes, adapters are required. The ID1300-XDS uses the modern USCAR connector. The factory GTR harness uses a Denso style connector. You will need six USCAR to Denso PNP adapters (ID P/N 90.3) for a clean, non-splicing electrical hookup.
Why is the ID injector data critical for the RB26 when using high-flow injectors and Haltech or MoTeC ECUs?
Injector Dynamics provides validated Dead Time (Latency) and Flow vs. Pressure tables. This data is mandatory for the RB26 because the cylinder-to-cylinder balance is critical on this high-RPM, individual throttle body (ITB) setup. Accurate data ensures all 6 cylinders receive the same fuel mass, preventing hot spots and engine failure.
Does the ID1300-XDS maintain an ideal spray pattern, even at its large flow rate?
Yes. The internal design and nozzle architecture are optimized using computational fluid dynamics (CFD) to ensure the fuel is finely atomized and the spray geometry is maintained. This leads to superior air-fuel mixture preparation, which is essential for maximizing combustion efficiency and minimizing cold start roughness on the RB26.
Why is the all-stainless construction critical for the RB26’s fuel system when running E85?
The all stainless steel internals provide maximum corrosion resistance and durability. The GTR's fuel system is often exposed to high temperatures, and E85 is corrosive; this construction prevents internal wear and ensures the injector maintains its precise flow matching for years of reliable use.
