Does anyone know this one, I was thinking today at work about changing injectors on my 1995 STS. I have a set off my 2001 Corvette with only 6000 miles on them, would they fit? I know LS1 and LT1 injectors was interchange.The injector size is 24 off the LS1 injectors! Thanks!

They should fit physically. They may have a different electrical connector. Additionally, LS1 fuel flow ratings are at 58 psi. Ours are rated at 45psi. IIRC the LS1 injectors are 28#/hr @58psi, which is 24.6#/hr@45psi... slightly larger than stock, but the computer can make up the difference. You may lose power on the top end due to a richer condition.

(rich condition doesn't get translated to WOT fuel trim - only lean to prevent burning up pistons)

They have different part numbers.

I went today and tried to plug the LS1 injectors to my surprise it plugged in. So it might work.

I would also check and see if the coil resistence is similar between the two before you start releasing magic smoke from modules. You don't want to try powering up those injectors if they require different voltage, or amperage levels. I would bet that they are nearly identical that way, but better safe then sorry.

I did some research it appears that both use low impedence injectors. Another plus!

All GM MPFI injectors are high impedance. I don't know of any exceptions. Additionally, most if not all ford injectors are the same. It's those imports you have to watch out for.

High impedance = 12-16 ohms, which is what you have, not low impedance.

Ok maybe it was high either way they will work!
