Injector Dynamics Fuel Injectors for Holden

The Holden Commodore and Monaro are uniquely Australian performance platforms — and with the factory long gone, the aftermarket is the only path to keeping these cars competitive on the street and track. Whether you are building a turbo LS1 VT Commodore, converting a VZ Monaro to E85, or chasing serious power from a W427 or E-Series HSV, Injector Dynamics offers precisely characterised, dynamically matched fuel injectors with direct plug-and-play fitment for every major Commodore and Monaro variant.

Commodore V8 — LS1 (VTII / VX / VY)

The 5.7-litre LS1 Commodore is one of the most popular V8 platforms in Australian motorsport and street performance. From supercharged street builds to turbo drag cars, these engines respond dramatically to fuel system upgrades — and the factory injectors become the limiting factor as soon as forced induction or E85 enters the equation.

A set of eight Injector Dynamics ID1050x injectors supports approximately 640 to 880kW at the crank on petrol at 80% duty cycle — more than enough for the vast majority of supercharged and turbocharged LS1 builds in Australia. On E85, eight ID1050x injectors support up to approximately 440 to 640kW at the crank, which covers even aggressive forced induction street and track setups.

For extreme builds pushing beyond those numbers — large single turbo setups, methanol, or dedicated drag cars — the ID1300x and ID1750x provide the additional flow headroom needed. The ID1300x was designed specifically for alternative fuels with all stainless steel internals for extended E85 service life.

Commodore V8 — LS2 (VZ) and W427

The 6.0-litre LS2 in the VZ Commodore and Monaro, and the 7.0-litre LS7-based engine in the W427, are serious performance platforms that reward proper fuel system upgrades. The same ID injector range applies — ID1050x for most builds, stepping up to ID1300x or ID1750x for high-boost E85 and methanol applications.

The W427 in particular is increasingly being modified by owners who want to extract even more from what was already Holden's most powerful factory car. Upgrading to ID injectors with full characterisation data allows tuners to calibrate the fuel system with precision — important on a platform where the factory ECU calibration is already sophisticated.

Commodore V8 — E-Series HSV

The supercharged LS-based engines in HSV's E-Series models (E1, E2, E3, including the GTS, Clubsport, Maloo, and Senator Signature) are already making serious power from factory. Once the supercharger pulley is reduced, the intake is upgraded, or E85 is introduced, the factory injectors quickly reach their limit. A set of eight ID1050x injectors provides massive headroom for these builds on both petrol and E85.

Commodore V6 — VT / VXII / VS/VY SCV6

The Ecotec and Alloytec V6 Commodores have a growing turbocharged and supercharged aftermarket scene — particularly the 3.8-litre supercharged V6 in the VS/VY SCV6. These engines benefit from injector upgrades when forced induction is added or boost is increased beyond what the factory injectors can support.

A set of six ID1050x injectors on a turbocharged V6 Commodore supports approximately 480 to 660kW at the crank on petrol — well beyond what most V6 builds will ever reach. On E85, six ID1050x injectors still support up to approximately 330 to 480kW, providing enormous headroom for even the most ambitious V6 turbo builds.

Monaro — LS1 / LS2

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

Why Injector Dynamics for Holden?

Every set of Injector Dynamics injectors ships with complete characterisation data — dynamic slope flow rates, dead time values across voltage and pressure ranges, and dynamic flow matching at multiple pulse widths. This data is compatible with all major ECU platforms used in the Holden tuning community including Haltech, MoTeC, Link, HP Tuners, and EFI Live. Your tuner loads the data directly into the ECU for accurate fuelling from the first start-up — no guesswork, no hours of dyno time chasing idle quality or cold start issues.

All ID injectors are fully compatible with petrol, E85, E100, and methanol. The corrosion-resistant stainless steel internals are designed for extended service with aggressive fuels — critical for the many Commodore and HSV owners running E85 in Australia.
