Injector Dynamics Fuel Injectors for Holden

This collection covers Injector Dynamics fuel injectors and fuel system components with direct fitment for Holden Commodore, HSV and Monaro platforms, from the Ecotec and supercharged V6 through to the LS1, LS2 and LS3 V8s and the LS7-based W427. Injector sizes run from ID1050x through ID1300x, ID1750x and ID2600x, each supplied as a dynamically matched set with complete characterisation data. Also listed here are Injector Dynamics fuel filters, filter elements, sensors and the BPC100 brushless pump controller.

Choosing the Right Part

Commodore V8 — LS1 (VT II / VX / VY)

The 5.7-litre LS1 Commodore uses a 60mm injector set of 8. Eight ID1050x injectors support approximately 640 to 880kW at the crank on petrol at 80% duty cycle, and approximately 440 to 640kW at the crank on E85. For builds beyond that — large single turbo setups, methanol or dedicated drag applications — the ID1300x and ID1750x provide additional flow headroom. The ID1300x was designed specifically for alternative fuels with all stainless steel internals for extended E85 service life.

Commodore and Monaro V8 — LS2 (VZ)

The 6.0-litre LS2 in the VZ Commodore and VZ Monaro uses a 48mm injector set of 8. The same sizing logic applies: ID1050x for most builds, stepping up to ID1300x or ID1750x for high-boost E85 and methanol applications.

HSV E-Series and W427 — LS3 / LS7-based (VE)

HSV E-Series models (E1, E2, E3, including GTS, Clubsport, Maloo and Senator Signature) and the W427 use a 34mm injector set of 8. Once supercharger pulley, intake or fuel changes are made, the factory injectors reach their limit; ID1050x provides substantial headroom on both petrol and E85. Full characterisation data allows tuners to calibrate precisely on platforms where the factory ECU calibration is already sophisticated.

Commodore V6 — VT / VX II and supercharged VS/VY

The Ecotec and Alloytec V6 Commodores, including the 3.8-litre supercharged V6 in the VS/VY SCV6, use a 60mm injector set of 6. Six ID1050x injectors support approximately 480 to 660kW at the crank on petrol and approximately 330 to 480kW on E85.

Monaro — LS1 / CV8 and CV8-Z

The CV8 and CV8-Z Monaros share LS1 and LS2 drivetrains with the Commodore, so the same fitments and sizing recommendations apply. Select "Monaro (LS1)" or "Monaro (LS2)" when ordering.

Fitment identifiers to confirm

Before ordering, confirm your chassis code (VT II, VX, VX II, VY, VZ, VE, E1/E2/E3), engine family (Ecotec V6, supercharged V6, LS1, LS2, LS3, LS7-based W427), injector length (34mm, 48mm or 60mm) and set size (6 or 8), plus your intended fuel — petrol, E85, E100 or methanol.

Installation & What You'll Need

Installation and tuning by a qualified professional workshop is recommended. Injector changes require the fuel system to be depressurised and the rail removed, and the vehicle must be recalibrated before it is driven.

You will need the correct length injector set for your chassis, fresh O-rings and clips as required, and an ECU capable of accepting injector characterisation data — Haltech, MoTeC, Link, HP Tuners and EFI Live are all used in the Holden tuning community. If you are moving to E85, E100 or methanol, review the rest of the fuel system at the same time: this collection also lists the IDF750 and F1250 in-line fuel filters, replacement elements, O-ring kits, filter mounts and brackets, a dual fuel pressure/temperature sensor to suit the ID750 filter, and the BPC100 brushless pump controller, available with or without the E5LM fuel pump.

FAQ

Will Injector Dynamics injectors fit my Commodore without modification?

Injector Dynamics offers direct plug-and-play fitment for the major Commodore, HSV and Monaro variants listed above, provided you select the correct injector length and set size for your chassis and engine.

Are these injectors E85 compatible?

Yes. All Injector Dynamics injectors listed here are compatible with petrol, E85, E100 and methanol, with corrosion-resistant stainless steel internals for extended service with aggressive fuels.

What is characterisation data and why does it matter?

Every set ships with dynamic slope flow rates, dead time values across voltage and pressure ranges, and dynamic flow matching at multiple pulse widths. Your tuner loads this data directly into the ECU for accurate fuelling from the first start-up, rather than estimating idle quality and cold start behaviour.

Which size should I choose for a supercharged E-Series HSV?

ID1050x provides substantial headroom for most supercharged E-Series builds on petrol and E85. ID1300x, ID1750x and ID2600x are available where higher flow is required for methanol or high-boost applications.
