Does anyone know for certain what size the LS2 injectors are on a 2006 GTO?

I have heard 32lb.

As the saying goes "Been there, done that."

The search reveals approximations, but nothing exact.

That is why I post. I hope I am not shifting the earth's rotation by asking simple questions. After all, isn't that a function of the forum?

Perhaps you know the exact flow rate?

I don't know, but I'll have a set of 42# up for sale shortly if you want to upgrade :).

Okay, so where did you get the information? I know that the stock fuel pump pushes 40 GPH, but I don't know what that equates to in PSI. I suppose I would need to know the diameter of the fuel line.

Now, for the guys with the 42 LB injectors . . . what are they for. I understand the electrical connections are different for LS1's and LS2's. But, 42 LB is the size I am looking for.

Thanks!

This is correct.

Will 05 LS2 injectors fit 04 LS1 pigtails?

04 and 05-06 have different plugs. My 42's will fit an 04 directly or you have to use pigtail adaptors to use them in an 05-06- I have them on my 05 using the adaptor harnesses.

For an LS1, injectors are "EV1"-type, regardless of the # size and are direct plug and play. For an LS2, if you want plug and play, they must be "EV6" -type, otherwise, like kwiktsi said, you'll need a harness adaptor.
