I googled for "TBI injectors" and it came back with a butt load of sites that sell new or reconditioned injectors. Can anyone suggest a place/site to get them? I'd consider getting recondition injectors as long as cleaned and flow checked right.

btw, I need 5.7 injectors, if that matters.

Personally, for TBI injectors I would just go to a junkyard and grab some and then put new filters on them and be done. TBI injectors basically never go bad.

 

These 75lb'ers just went for $46 on ebay, though the serial numbers are filed off the top of the injectors for some reason?

Does the Holley 502-6 come with #68 injectors? I found a pretty good deal on one for the same price that Turbo City sells there Hi Flow #68 injectors per pair.

 

Good possibility it was done to cover something up. Like maybe they are the '94-'95 7.4l injectors. Which flow 75#/hr at 30 psi, which is stock for that unit. And 46#/hr at 13 psi, hmmm.

The ad stated the numbers were removed in the rebuild process. Doesn't make sense to me, they are laser etched into the top. Would need to sand/bead blast the dickens out of them to remove the numbers.

Several foks here have purchased ePay TBI injectors and received something other then advertised. To be honest, if it were me selling the injectors, I would take a picture of the top showing the numbers. And post that in the ad.

I have a couple of pair of GM injectors without numbers, they are just gone.

Many replacement injectors are sold without etched numbers as well.

I am thinking it is to cover something up as well.

PS- I wouldn't buy larger injectors. My 305 ran just fine with 30 PSI of fuel pressure and some tuning.

GPSorenson makes what I consider a good injector, they take all the pressure I need to dish to them and then some. They are about $100.00 each at your local Autozone.

 

Thanks Fast355. I know the GPSorenso brand cause I got my TBI rebuild kit at Autozone. What about the "flow matched" injectors? Is that something that I should look at?

Qoute from Turbo City:
"While the stock injectors can have a variance of up to 15%, the Turbo City injectors are matched to within 1% of each other! A dyno test has even proven a gain in horsepower!"

 

A problem with your wiring and/or computer will short out a TBI injector in an instant. I've personally seen it happen. They do go bad.
But yes you should always have junkyard injectors checked out by a pro. I learned that the hard way with a set of TPI 22lbs that had plugged filters. Nothing like tearing down a TPI intake twice!
