Rotary builds on E85 or plenty of boost get a direct-fit pair of Injector Dynamics ID1750-XDS injectors for the Mazda RX-7 with an 11mm top O-ring, sold as a set of 2. They add fuel over stock, with better low-pulse behaviour than the ID1700 they replace.
Pro Speed Racing is the Main Wholesale Distributor for Injector Dynamics in Australia and New Zealand, officially appointed by the manufacturer, and supplies these alongside its other aftermarket car parts. Browse the full Injector Dynamics range for other sizes and service parts.

2 x ID1750-XDS injectors
11mm top O-ring to suit the RX-7
Scroll to Technical Specifications below for the flow figure, pressure rating and connector.
From ID1700 to ID1750
The ID1750-XDS is the successor to the ID1700, itself a product of the Injector Dynamics and Bosch Motorsport partnership. Injector Dynamics added top-end flow while keeping minimum fuel mass where it was, improved balance between injectors at short pulse widths and cut pressure sensitivity. The internals remain corrosion resistant, so alcohol fuels are no problem. Rotaries are thirsty. This helps.
Fitment and service parts
The 11mm top O-ring is specific to this version, so confirm your RX-7's injectors use the same size and compare the length too. The Vehicle Fitment tab shows the confirmed applications. If yours turns out to use the 14mm top instead, the RX-7 pair with the 14mm top O-ring is the one to order.
Technical Specifications
Nominal Flow Rate: 1728cc/min @ 3.0 Bar (43.5 psi), Using E10 Emissions Certification Fuel at 49 Degrees C (120F)
Maximum Differential Fuel Pressure: 7.0 Bar (101.5 psi)
