1000cc Celica 1ZZ-FE 2ZZ-GE Fuel Injectors

Advantages of 1000cc Injectors for 1ZZ-FE and 2ZZ-GE Engines

• Increased Fuel Flow: Supports significant power increases in both engines.
• Tuning Flexibility: Allows for precise fuel management across a wide range of engine modifications.
• Future-Proofing: Provides headroom for further engine upgrades without needing to replace injectors again.
• Consistent Spray Pattern: Engineered to maintain optimal fuel atomization even at higher flow rates.

Considerations When Upgrading to a 1000cc 

1ZZ-FE and 2ZZ-GE Fuel Injector

• ECU Tuning: Both 1ZZ-FE and 2ZZ-GE engines will require custom ECU tuning to properly utilize these high-flow injectors.
• Fuel Pressure Regulator: May need upgrading to maintain proper fuel pressure with the increased flow.
• Fuel Pump: Higher capacity fuel pump might be necessary to supply adequate fuel for these injectors.

Why Excess?

See for yourself

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.
