Where's the best place to get a TPI Injector and what brand?
I might need a single TPI injector to get my Trans Am running right again and I'm pretty much flat broke so I was wondering if you guys knew where I could get a decent and reliable TPI fuel injector for less then the $80 some that Advance Autoparts is asking for? Also what is a good brand to stick with the remaining stock GM (AC Delcos?) fuel injectors?
Would you have any reccomendations?

http://www.summitracing.com/parts/VNM-HP-619-8/ this is what i run. youre 305 too, should work but a whole swap would be needed. theyre rated 10% more flow for extra horsepower. but replacing one would off set the whole shabang. post your description on the tech-forum, this guy(SpitotRs305) he'll help you, tell him i refered you.

Re: Where's the best place to get a TPI Injector and what brand?
I RECENTLY BOUGHT A SET OF ACCEL BRAND FUEL INJECTORS 21# FROM JEGS. THEY WERE $278.00 DELIVERED. THE TECH I TALKED TO AT JEGS LOOKED IT UP AND SAID THESE WERE CORRECT FOR A 350 TPI (89). THEY WORK GRAET, VERY HAPPY.

Re: Where's the best place to get a TPI Injector and what brand?
Thanks for all the great suggestions and offers! I still have to figure out what my problem actually is. It might not be a fuel injector at all. I don't know for sure. I'm going out to do a OHM test and check all the lines right now.

Re: Where's the best place to get a TPI Injector and what brand?
I just tested the OHMs in each fuel injector but I'm not sure what the results mean. I've heard they should all be within .5 of each other and none of them were. I first tested cold, then warmed it up to operating temperature and tested it warm with the engine off. Here is what I got...
Chart explanation: OHMs reading - (Passenger side)Cylinder__Cylinder (Drivers side) - OHMs reading
16.6 - 8________7 - 11.6
3.9 - 6________5 - 16.1
16.1 - 4________3 - 14.7
10.7 - 2________1 - 15.3
Note: Cylinder 6 fluctated from 3.9 to 4.0, and Cylinder 3 fluctuated from 14.8 to 14.8.
Hot...
11.0 - 8________7 - 11.5
1.8 - 6________5 - 16.7
11.5 - 4________3 - 12.0
8.3 - 2________1 - 13.3
The readings were alot lower when it warmed up, and they were all over the place. None of them were within .5 like I heard someone say in a youtube tutorial.
What does all this mean?

Re: Where's the best place to get a TPI Injector and what brand?
irocuroc is right, you need a full set of injectors.
you have one that is checking ok, #5. the rest are junk.
with a good set of injectors, the ECM sees around 6~7 amps of current.
with the hot resistance you gave, the ECM is seeing around 16 amps of current. sooner or later that will kill the ECM.
i just recently had a 91 vette that ran so bad, it had to be towed to the
shop. the injectors in it were not as bad as yours are.
i put a set of Bosch 3s in it and it fired up and ran great, the owner said its been years since it idled that smooth.
i don't know if they make the Bosch 3s in 19 pound or not.
you can contact either southbay or FIC to find out.
