How do I identify ls6 28.8 injectors?

MSGHUFF · 02-02-2006, 05:35 PM

I bought some injectors that supposedly came from a 2004 Zo6 I got them and tried to cross ref the part numbers but am not having any luck? Can anyone help?

MSGHUFF · 02-02-2006, 06:09 PM

found my own answer...
Delphi / Bosch
28 lb / hr Injector
Part Number 12561462 (Bosch # 0 280 155 931) - This is a LS1 factory GM injector.
Static Flow Rate: 28 lb/hr (294cc) @ 43.5PSI (300kPa)
Fan spray pattern for superior atomization.
High pressure capability
High Impedance / High-Z

That would be a 32.5 lb/hr at 58PSI and looking at a stock 04 LS6 IFR table, they appear to use around a 29.3 lb/hr injector.

29.14, 29.33, 29.51, 29.7, 29.89, 30.01, 30.2, 30.38, 30.57, 30.75, 30.94, 31.06, 31.25, 31.44, 31.56, 31.75, 31.93,

FWIW The info I got was copied directly from the Delphi/ Bosch website using the part numbers off mine and a friends zo6

This is a good question, I've got the same injectors sitting in my garage waiting to go in. Gm part numbers match and delphi pt#'s match. The stock IFR for 28.8lb injectors is different, check them out

28.70852 28.89454 29.08055 29.26657 29.45258 29.57660 29.76261 29.94863 30.13464 30.25866 30.44467 30.63069 30.81670 30.94072 31.12673 31.31275 31.43676

I want to make sure I use the right IFR when I put them in.

Has anyone found an answer?

Actually there are three part numbers:

GMP-12554271 - 97-98
GMP-12561462 - 01-04
GMP-12482704 - 01-04

Can you be more specific on the vehicle models for those #s. We're talking about Z06 LS6 injectors.

MSURacing · 04-28-2006, 10:35 AM

Those are all the numbers I have. They all flow the same amount, just the 1248 are more than likely the LS1 and the 1256 are for the LS6.

my 98's were 12554271
I looked at ones off a stock 01 SS and they were 12561462

LostCauseZ06 · 09-12-2006, 09:30 AM

i just looked at my injectors for my 02 Z06, they are 12561462

I am planning on swaping my stock ls1 intake for the ls6 out of a '04 cts-V including the fuel rails and the injectors. I did a little research and ls1 stock injectors are 24 lb/hr and the ls6 (12561462) are 28 lb/hr. My questions is if I need to retune my PCM? thanks in advance..
