Default LS6 Corvettte

Good afternoon all.
Had the car at a dyno shop last week. We need new 26lb injectors.
Where are you guys buying yours?
Thank you

The LS6 came with 28.5 lb injectors, only the ‘99 came with 26.3 units. Are you putting an LS6 into a ‘99, and want to match existing programming for initial running or similar?
As to where to buy, I’ve had good luck with the parts forum here, and then used a DIY apparatus to clean and verify functionality.

Yes, LS6 in a 1999 Corvette.
We have the wrong injectors at this time.
Thanks for your reply. I will check the parts forum.
Cheers!

If you plan to make anywhere north of 430 rw don't go with factory but with something larger aftermarket. You have to adapt the tune anyway, so adapt now for injectors which will meet all your current and future goals.

Are there larger displacement stock GM truck LS engine injectors "Plug and Play"?
I seriously do not know... Just a thought.

I'm not certain if all the OEM injectors are physically the same diameter, in that the O-rings are the same size, or have the same depth into the intake. If I had to guess, I'd say yes, but do check before buying. If they all interchange physically, all you may need to do is get new harness plugs that interface with your new injectors, where the harness electronically plugs onto the injector. I have an LS7 in my 2000, and had to snip all 8 connectors, then solder the 8 appropriate pigtails on. Pretty easy if you've soldered before. Only 2 wires......

Most OE PCMs require high impedance injectors ... +/- 12-16 Ohms.
Be aware that there are also low impedance injectors on the market ... +/- 2-6 Ohms.
As a rule, they are not interchangeable.
