The Toyota 1JZ engine, renowned for its robust design and tuning potential, benefits greatly from high-flow fuel injectors. Our 1000cc injectors are specifically designed to meet the demands of modified 1JZ engines:
Key Features
Flow rate: 1000cc/min at 3 bar (43.5 psi)
Direct fit for 1JZ-GE VVT-i fuel rails
High-impedance design for OEM-style operation
Precision-machined for consistent spray patterns
1JZ 1000cc Injector Performance Benefits
Support for significant power increases, ideal for turbocharged applications
Improved fuel atomization for more efficient combustion
Capable of supporting over 500 horsepower per cylinder
1JZ 1000cc Injector Compatibility
These 1000cc injectors are perfect for various 1JZ engine configurations, including:
1JZ-GE VVT-i

Tight Testing Controls
All Excess Injectors are tested on our custom built test bench to J1832 standards.
Pressure is electronically controlled at 3 bar
Temperature is controlled at 21°C
Votage is controlled at 14V
Because the testing parameters are so tightly controlled we get the same results everytime we test them.
Tightly Grouped Sets
We don't just dynamically flow test injectors we also measure the dead time of each injector. Every set is:
Dynamically flow matched within 1%
Deadtime matched within 2%
Exact Match Data
Every set you buy comes with tuning data exactly matched to your set. It is based on how that set performed on the test bench. Saves dyno time tuning injectors and you get a perfect result every time.
data formatted for 11 different ECU/software types
no two tune files are the same
tuning data is matched exactly to your set
How many points are tested?
over 6,500 flow points are tested and recorded on every injector.
over 265,000 measurements for flow, pressure, voltage etc are recorded for every injector
tuning data specific to your set is available for download to make an easy tune
All of these results are stored on our cloud server, you can log in to view the data specific to your set at any time.
Lifetime Guarantee
If an injector has an issue not related to contamination or damage from external forces we simply replace the injector for you. It's that easy. We know exactly how your injector set should flow and what the deadtimes are because we store that information on the cloud server. We just replace the injector with another one that matches your injector set exactly.
