All Performance 4x4 12mm modified fuel injection pumps are built in-house to the highest standard, using a combination of genuine components, custom over-engineered internals, and precision calibration processes.
Each pump is developed through extensive in-house R&D, utilising custom test plans and calibration procedures to ensure maximum performance, consistent fuel delivery, and reliable operation in real-world applications.
Designed specifically for Toyota LandCruiser 1HD-FT engine, this 12mm Performance Injector Pump is a proven solution for vehicles requiring significant power increases while maintaining drivability.
Performance & Application
Our 1HD-FT 12mm performance injector pumps are capable of supporting up to approximately 260HP when paired with the correct supporting modifications.
We have successfully built and tuned these platforms to 350HP+, however, achieving these levels requires a fully built engine and complete supporting system.
For optimal performance and reliability, supporting modifications should include:
- Turbocharger upgrade
- High-flow intake and airbox
- Intercooler upgrades
- Exhaust system improvements
- Professional dyno tuning
Pre-Calibrated Power Options
To suit a range of builds, these pumps are available in pre-set horsepower calibrations:
👉200HP
👉230HP
👉250HP
Selecting a calibration close to your final power goal ensures the best overall performance, drivability, and tunability.
Engine Condition & Recommendations
As power levels increase, engine condition becomes critical. On older or high-kilometre engines, some smoke haze may be present, particularly if supporting components are not in optimal condition.
Before installation, we strongly recommend:
- Valve clearance adjustment
- Compression testing
- Injector condition check or replacement
These steps help ensure the engine can safely support increased fuel delivery and performance demands.

Core Deposit Explained
Performance 4x4 operates on a core exchange system for our injector pumps.
If you require an injector pump to be sent out, please select the “core deposit” option. This includes a $600 refundable charge, which will be refunded once we receive your old injector pump.
Please note: your old injector pump must be complete and not disassembled to be eligible for the refund.
We work hard to keep turnaround times as fast as possible so you can get back on the road sooner.
-
Send-in service: Typically completed within 5–8 days
-
Core exchange option: If we have a pump ready to go, dispatch is often even faster
If a pre-built core isn’t currently available, lead times can extend up to 3 weeks, however, this isn’t always the case, so we recommend getting in touch for the most up-to-date availability.
