I have been looking all over the forums and I can't seem to find the stock size injectors for a 02 LS1. I have seen 24lb, 26lb & 28lb. I even asked Racetronics and they said 24lb for a 02 LS1.

Can anyone clear this up for me.

Thanks in Advance

 

Racetronic 24# injectors are base off a 3 bar @ 43 psi and the stock 02 ls1 motors run 28# injectors on a 4 bar @ 58 psi. So yes the Racetronic injectors will work fine

 

Will I have to tune the Injector flow rate vs KPA VAC for the Racetronic #24 injectors?

Thanks JJ

 

should not have to they are the same size injector

 

so i bought a 2000 c5 had a blown motor and i found a used ls1 from a 2002 camaro ss! Needs injectors but the 00c5 takes 26# if im not mistaken but the 02 ss takes 28! The 00c5 computer is programmed for the 26# but the the motor i got now is made for 28# what should i do? Im ready to order some right now but dont wanna get this wrong so i signed up to get sum help! Thanks in advance!

 

Swap the injectors from the old engine to the new one.
Connectors are the same, this way your computer will see the correct injector.
