I had my car built by IR Performance back in 2022/2023. For the fuel system, they installed the “IRP Competition Fuel System”. I am trying to get my car tuned and need to find out what injectors are installed; when looking at the part numbers on the primary injectors, they appear to be ground off on both injectors (please see picture). Does anyone with the “IRP Competition Fuel System” know what the primary injectors are? Seeing the numbers sanded/ground off is also a bit puzzling so if anyone has any insight on why they are like that I would appreciate it. Thank you!

Looks like it is 0 280 158 ___.

 

your answer should be in the tune. what ecu do you have?

 

@FDAUTO Good idea, I didn’t think of that. Thank you. And Haltech 2500

 

You don't have any pics attached but as FD Auto stated, install NSP, connect, and look at the configuration. It should show 2 rotor and have the injector sizes there, your invoice would also have them listed.

IRP offered different injector options with their fuel system.

 

@Molotovman I appreciate the NSP guidance, I will look into that when I get a chance. And unfortunately my invoice only says “IRP Competition Fuel System”; I was hoping for some more detail as well. Thank you!

 

IRP was traditionally using FIC injectors . FIC might have some more information

 

They're probably Bosch and 725/2000cc.

 

FWIW, i always buy fuel injectors by the Bosch part number. someone rubbed off the last 3 digits.

i run the same EV 14 injectors for both primary and secondary. the EV14 pintle weighs much less than the EV6 pintle. this allows them to function/atomize well at very low pulse widths.

i run the 0280158333. i buy then from Ballenger for around $150 each. they flow 1462 at 3 BAR and 1650 at 4 BAR.

i bought a set of ID 1300s for primaries a couple of years ago and they didn't work correctly so they are sitting in a box.

their Bosch pn is 0280158412.

you probably have the 412s... have them flowed for your answer.
