Frequently Asked Questions About the ID1750-XDS Injectors

Why is the ID1750-XDS the critical component for my 87-88 FC RX-7 turbo build?

The ID1750-XDS provides the massive 1750cc flow rate required to safely fuel highly boosted 13B-T rotary engines. Its high flow and precise linearity are essential for supporting extreme horsepower and maintaining engine stability under load.

How does the part number 1750.11.03.60.11.2 ensure fitment in the 87-88 RX-7?

This specific Injector Dynamics configuration is designed for the FC RX-7 and requires an aftermarket top-feed fuel rail system. It includes the correct 11mm adapters and seals for secure mounting into the manifold runners.

What is the key benefit of the ID1750-XDS's tuning data for the rotary engine?

Every set comes with comprehensive characterization data vital for professional tuning. This data enables the ECU to accurately control the injector at short pulsewidths, resulting in a smoother idle and reliable driveability.

Is the ID1750-XDS suitable for E85-only use in my turbocharged RX-7?

Yes, the ID1750-XDS features stainless steel construction which is highly resistant to corrosion. This makes it a durable and reliable choice for RX-7 owners running E85 (ethanol) or other high-alcohol content fuels.

What mandatory supporting modifications are needed for these 1750cc injectors?

Installing the ID1750-XDS requires significant supporting mods: a high-output fuel pump, a standalone ECU, and typically an adjustable fuel pressure regulator to reliably manage the high fuel flow.
