Hondata 2000cc Fuel Injector Set for 2017+ Honda Civic Type R / 2024+ Acura Integra Type S [FK8/FL5/DE5]

Introducing our high flowing FK2,FK8, FL5 and DE5 2000cc injectors, custom designed and proudly manufactured in the US. Elevate your performance with these high-quality injectors, providing a remarkable 90% increase in fuel delivery compared to the stock FK2 / FK8 / FL5 / DE5 injectors. Stock starting with a smooth idle while preserving a stock like spray pattern. Take your Civic Type R and Integra-S fuel capabilities to the next level with this upgrade for unprecedented fuel delivery and efficiency.

The Hondata designed, US manufactured 2000cc fuel injectors deliver a spray pattern for great fuel atomisation with 90% more flow than a stock Civic Type R (either FK2, FK8 or FL5) or Integra-S injector. These injectors are calibrated at 100 BAR and tested to over 240 BAR. Hondata has tested these injectors to over 550 HP on E85 which indicates a HP capacity over 700hp on race fuel.

• Four 2000cc Hondata injectors
• E85 compatible
• Stock like atomization
• Designed and manufactured in the USA
• Sold as a matched set of 4.

Firstly, check out the injector tech video. This video was filmed with the 1530 injectors, but the data presented also relates to the 2000cc injectors.

Summary.

Increasing injector flow while maintaining atomisation requires countersinking the holes. Hondata replicated the stock injector hole design. Simply drilling a hole does not optimise fuel atomisation. (think firehose)

The injector fuel exit must be counter-bored stepped for optimal atomisation.

Hondata tested with a microfine grid under each injector to determine the fuel delivered to each segment.

Injector tips

• Stock injectors have 7 counter-bored holes
• Hondata 2000 injectors have 8 counter-bored holes
• The competitition 2000cc injectors have 6 counter-bored holes and 1 non counterbored.

Note the competitor injector spray cone and bend angle is smaller than stock.

Stock injector atomisation 100 bar

Hondata 1530cc injector atomisation 100 bar

Competition injector atomisation 100 bar

Note the bulk of the spray is in the centre. 

Fuel pressure

Meaning, if you exceed 260 bar fuel pressure you wont know how much you over-pressureize. We've seen no powergains over 220 bar. Higher pressure improves atomisation but reduces fuel volume.

Injector lockup

When the fuel pressure is too high, the injector can lock up and stop delivering fuel. Fuel rails and pumps are very noisy as far as pressure waves are concerned. You might request 200 bar, but injector closing and pump operation can spike this to many bar higher. This pressure wave noise is too brief to be measured by the stock Honda fuel rail pressure sensor. Hondata injectors are designed to function between 200 and 240 bar (and a lot higher values). Higher pressures may improve atomisation but decrease fuel pump volumetric efficiency - as in your system delivers less fuel. (Read this Hondata test on in tank pumps)  We have seen competing injectors lock up at 230 bar, which is bad for your engine.
