Performance 4x4 10mm 1HZ injector pumps are upgraded from standard and built in-house using genuine components and precision-engineered custom internals. Each pump is developed through extensive in-house R&D and calibrated using proven test plans to ensure reliable performance, accurate fuel delivery, and consistent results.
This upgraded unit features boost compensation, allowing fuel delivery to increase in line with boost pressure. The result is improved drivability, smoother power delivery, and better overall efficiency compared to a standard non-compensated pump.
Designed specifically for Toyota LandCruiser 1HZ engines, this pump represents a first-stage, mild upgrade - ideal for vehicles running a basic turbo setup while maintaining engine reliability.
Performance & Application
This injector pump is suitable for applications up to approximately 150HP, when paired with appropriate supporting modifications.
It is best suited to touring and towing setups, where the focus is on:
- Usable, responsive power
- Improved drivability
- Maintaining engine longevity
Recommended supporting modifications include:
- Turbocharger (low boost setup)

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.
