Frequently Asked Questions About the 93-95 RX-7 (11mm) ID1050-XDS Injectors
How do I know if I need the 11mm RX-7 ID1050-XDS kit instead of the 14mm version?
The 11mm kit is for fuel rails designed around the smaller 11mm top-feed bore. Some aftermarket rails for the FD use this size for tighter packaging or specific injector spacing. Always match the injector size to your rail’s top-feed diameter.
Are these 11mm ID1050-XDS injectors still a plug-in solution for the factory wiring harness?
Yes—just like other FD kits, you’ll typically use plug-and-play adapters to mate the ID1050-XDS EV6 connector to the FD’s factory harness. No cutting or soldering required.
Are the ID1050-XDS injectors appropriate for primary injector duty on a rotary engine?
Absolutely. Their precise low-pulse control makes them ideal as primaries, giving stable idle and crisp throttle response—important on the FD’s sequential system.
Can these 11mm injectors support E85 on an FD with upgraded twins or a mild single turbo?
Yes. The XDS series is fully stainless internally, so they handle E85 without corrosion issues. For higher power builds, they are usually paired with larger secondaries for full fueling under boost.
Does this 11mm kit fit under the OEM intake manifold without clearance issues?
Yes. This 60mm-length 11mm-body injector fits properly in FD rails designed for it and clears OEM manifold runners without modification.
