19lb LB9 Fuel Injectors (8-set) 71K miles!

I have the original set of 8, 19lb fuel injectors from the LB9 (TPI 305) in my 1992 Trans Am GTA. All were in perfect working order when removed with only 71K miles on them!

I removed them because I bought a set of 30lb Accels due to other engine mods

They have since been stored correctly in the individual injector boxes with caps inside my house. All of the original O rings are perfect and not torn, they are still soft actually.

Attached is a picture I just took for this post.

I'm asking $220 OBO including shipping anywhere in the 48.
EDIT: Lowered to only $180 INCLUDING shipping!!!

Have you done an ohm test to see if they are still in factory spec. Should be 16.2 cold.

Nope, I'll grab them right now and my multimeter and post the results...

your window sticker says it's a 350.

You misunderstand. The 350 was STANDARD on the GTA. If you look to the right at the additional options you will notice a credit for the 350 and that 305 is listed.

The injectors are sold BTW.

Re: 19lb LB9 Fuel Injectors (8-set) 71K miles!

here's the deal.
Those injectors are Multitec's. they are worthless because the coils short out. As you see some of yours are starting to short out. In another few thousand miles, the resistance will drop event further, until the car is running like trash. hard starting, won't idle correctly, etc, etc. It won't even throw a code, the car just won't run right. Those injectors can't even be rebuilt.

Having said all that, I have a theory that 1989-1992 LB9 injectors are 21lb.
If you send me 4 injectors, I'll pay a fuel injection shop to flow them. This way I can see if my theory is correct.

after I'm done, I'll send them back to you.

I can already tell you that they are not. I have done custom tuning for my car for years and I know what the flow rate was in the stock bin.
