Injector Question

[ChevyNo1]

Hey guys . . . f-body owner here. I may need to buy a single injector and am wondering if you know where I might find a single green-top SVO 42lb injector? My buddy ( previous TTA owner ) told me you guys might know . . .

I accidentally put a post in the wrong section, but more details here:

Details

Thanks!

Several of the Buick vendors can sell you a new injector or inspect your old one.

Here is a place that can clean and inspect your old injector to see if it is still good.

Thanks Gary ...

The reason Dug posted this is because he was told by a few vendors that his injectors are not avail anymore. He could certainly purchase a complete new set of something else in a high ohm injector, but the ones he has now are almost brand new ... And money is a little tight at the moment.

The piston that broke in his motor really looked clean (lean) in comparison to the rest. I have a feeling the injector is not flowing as much as the rest, and just went too lean resulting in the fractured piston ... Since he just replaced the aluminum LS1 stock 5.7 block with a new 6.0 steel truck block and new low compression forged pistons, I just think he would be safe replacing that one suspect injector. Having it flowed on a bench would more than likely cost almost as much as purchasing a new one (if we can find a new replacement)

Anyway, he made 621rwhp / 684rwtq on a bone stock 10.1 CR motor with 12 psi of boost. and 91 octane pump gas.

Now, I just need to find where I can replace this so-called non-avail injector.

Thanks,

I see this frequently, and 99+ % of the time there is nothing wrong w/ the injectors...
Suggest you have all flow checked and cleaned....
2 checks you can do at your shop:
1. trigger the injector w/ 12vdc, and see if it cycles.
2. Check the ohm value w/ the meter, and then check to see if the coil is shorted to the body...

Clean and flow test 8 is $100.00

HTH,

Chuck, thanks a lot for your input, much appreciated. It just sucks doing this when in a few months I'll probably jump up to 60# injectors anyway, but I don't want to risk the new motor for sure.
