Injector Dynamics ID1050-XDS Fuel Injectors for 2JZ-GE Air-Assist - Set of 6

Injector Dynamics ID1050-XDS Injectors for the 2JZ-GE Air-Assist Configuration

Injector Dynamics lists part number 1050.30.02.60.11.6 under both Toyota and Lexus for the 2JZ-GE Air-Assist application, and it ships as a set of six. The air-assist variant of the 2JZ-GE uses a dedicated injector arrangement, which is why it carries its own part number rather than sharing one with the naturally aspirated Supra listing.

The ID1050-XDS behind that configuration is a corrosion-resistant motorsport injector rated at 1065 cc/min at 3.0 bar, with a compact body and a replaceable inlet filter. It gives an air-assist 2JZ-GE build meaningful headroom without moving to the largest units in the X-Series.

Key Features

• Supplied as a dynamically matched set of six injectors in the 1050.30.02.60.11.6 configuration
• Replaceable inlet filter to extend service life
• Corrosion-resistant internals for compatibility with all known fuels and extended service life on corrosive fuels
• Compact body that Injector Dynamics says fits more than 200 applications, including engines that use short-body injectors
• Improved internal flow path that raises output by five percent without sacrificing low-flow performance
• Stronger magnetic circuit for stable operation up to 10 bar
• Listed by Injector Dynamics for 2JZ-GE Air-Assist

Fitment

The manufacturer application entries for this part number are engine-and-manifold specific rather than year-and-model specific. Injector Dynamics publishes a different part number for the naturally aspirated Supra 2JZ-GE, so an air-assist manifold has to be confirmed before ordering.

Specifications

What's Included

• 6 Injector Dynamics ID1050-XDS fuel injectors in the 1050.30.02.60.11.6 configuration, supplied as one dynamically matched set.
• No box-contents list is published by the manufacturer for this configuration. Plan on the injectors alone and source seals, adapters or harness parts separately if the install needs them.
• Characterization data is published by the manufacturer rather than boxed with the set, and should be downloaded fresh before the engine is tuned.

About Injector Dynamics

The X-Series programme at Injector Dynamics exists because production-car injectors were not designed for high-boost alcohol engines. The ID1050-XDS came out of that work with an improved internal flow path, a stronger magnetic circuit and a serviceable inlet filter, and is catalogued by exact application rather than by generic flow rating.

FAQ

Use the manufacturer nominal rating of 1065 cc/min at 3.0 bar (43.5 psi), measured with gasoline at 52 C (125 F), then correct for the fuel pressure the build actually runs.

10.0 bar (145.0 psi), per the manufacturer specification table.

The manufacturer fuel compatibility statement reads: Compatible with all known fuels.

USCAR, as published in the manufacturer specification table.

Injector Dynamics matches injectors dynamically as a group, and its service department asks for the complete set when work is needed.

Correct fuel type and proper fuel filtration. Injector Dynamics states that failing to do so reduces longevity and is not covered.

It is the molded O-ring retainer fitted to all Injector Dynamics injectors. It should only be removed on the manufacturer's instruction, and it cannot be refitted.

It does. The cleaning and inspection service requires every injector in the set and identifies them by the serial number at the base of the connector.

Injector Dynamics argues that accurate characterization is the basis of all fuelling calculations, and publishes the data specifically so it does not have to be guessed.

Not automatically. Injector Dynamics lists Supra NA 93-98 2JZ-GE under a separate part number, so this air-assist configuration should only be ordered when the engine actually carries the air-assist manifold.

The air-assist 2JZ-GE was used across both brands, and Injector Dynamics repeats the identical part number under each heading rather than creating two configurations.

No. The manufacturer lists the engine and manifold arrangement only, which is why this listing carries no vehicle-year fitment tags.

Installation Instructions

Injector Dynamics publishes no installation procedure or torque values against this part number, so the steps below cover only its documented cautions and connector guidance and point to factory service information for the rest.

1. Confirm that part number 1050.30.02.60.11.6 is the configuration Injector Dynamics lists for 2JZ-GE engines fitted with the air-assist injection manifold before removing anything from the engine.
2. Note the serial numbers stamped at the base of each connector so the set can be identified later; Injector Dynamics requires them for service requests.
3. With the fuel system depressurised and isolated, follow the factory service information to free the rail. Injector Dynamics does not document rail removal for this application.
4. Keep the molded O-ring retainer intact. Removal is a manufacturer-directed modification only, and is permanent once done.
5. Check that the injector seats fully in both the rail and the port with the 60 mm body and its listed interfaces before committing to the install.
6. Where injector connectors are being built up, the manufacturer's method is to strip about 5 mm of insulation, pass the wire through the seal into the terminal, line the bare conductor up with the crimp section and crimp.
7. There is no correct pin order for power and ground at the injector; the manufacturer states the connectors are not polarity specific.
8. All fastener torques come from the factory service information for the engine, because no manufacturer torque value exists for this part number.
9. Enter the manufacturer's latest dynamic flow and offset tables for the ID1050-XDS into the ECU before the first start.
10. Prime the fuel system without cranking, check the rail and injector seals for weeping, and verify that the fuel filtration the manufacturer requires for warranty coverage is fitted.
