Performance 4x4 12mm 1HD-FT Extreme injector pumps are built in-house to the highest standard using a combination of genuine components, custom over-engineered internals, and precision calibration processes.
Developed through extensive real-world testing and in-house R&D, each pump is assembled and calibrated using custom test plans to deliver maximum fuel delivery, high power capability, and consistent performance in demanding applications.
Designed specifically for Toyota LandCruiser 1HD-FT engines, this pump is intended for high-performance builds where maximum output is the priority.
Performance & Application
Our 1HD-FT 12mm Extreme injector pumps have been tuned up to 350HP, with all supporting modifications and engine build.
This level of performance is well beyond standard engine limits and requires a fully built engine and complete supporting system to operate safely and reliably.
Supporting modifications should include:
-
Upgraded injectors
-
Turbocharger upgrade
-
High-flow air intake and airbox
-
Intercooler upgrades
-
Exhaust upgrade
-
Professional dyno tuning
Pre-Calibrated Power Options
To suit different build stages, these pumps are available in the following pre-set horsepower configurations:
-
270HP
-
300HP
-
330HP
Selecting a pump calibrated close to your final power goal is critical to achieving optimal drivability, tunability, and overall performance.
Engine Condition & Requirements
Depending on engine condition, some smoke haze may be present, particularly if supporting components are not correctly matched.
Before installation, we strongly recommend:
-
Valve clearance adjustment
-
Compression testing
-
Upgraded injectors
-
Verification of overall engine health

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.
Important Notes
