Hello,


I have a 1989 L03 305



I am looking to replace my injectors and I've done a bunch of research. I found out I need 40-45 lbs/hr for my fuel flow to help narrow down my fuel injector search. However, I can't find any information on these injectors below regarding their fuel flow. I'd hate to drop $200 on injectors that have too much or too little lbs/hr fuel flow. Would anyone be able to possibly assist me in finding out which injector has the correct fuel flow? Or could you possibly send me a link to stock replacement injectors for my L03?


Thank you!!

What's wrong with the ones you've linked-to? They ARE stock-replacement injectors:
1989 Chevrolet Camaro RS V8 - 5.0L vin E 305ci - TBI GAS OHV

One being in the "discount" line, and having a 1-year warranty instead of the other one with a "Limited Lifetime" warranty.

 

Thanks for the reply. The items say they fit any camaro motor from 82-92, including the 305 and 350. These two engines had different spray rates (40lb/hr - 55lb/hr). I want to to make sure I am getting the one that fits my engine (40lb/hr - 44lb/hr)

 

im almost 100% sure the 305 5.0 TBI sprays at 55 ib/hr. The 350 can honestly run on those as well as me how i know yet they usually come with 61/64 respectively.

EDIT: Info found.

For injectors they come in various flow rates. The common injectors that are found in the above TBI units are:
2.8l and 3.1l engines: 33 #/hr
4.3l engine: 45 #/hr (note: some units have different flow rate injectors. This is done to help with fuel distribution.)
5.0l engine: 55 #/hr
5.7l engine: 61, 65, & 68 #/hr
7.4l engine: 46*, 75 & 81 #/hr.

 

Hey where did you find that info? I found this chart here linked on thirdgen showing 40

/www.diy-efi.org/gmecm/component_info/tbi_injectors.html

 

That info is wrong, i got my info from http://www.dynamicefi.com/TBI_Fueling.php a member/mods website. Which is infact correct.

 

I actually found it on another thirdgen thread when I was doing my initial research haha.

Ghettobird, do you think either of the injectors I listed would be the correct fuel flow?

 

Yes 55 PPH is the correct flow rate for the LO3 305 5.0 TBI motor.

 

Sorry just noticed you asked about either of the actual links you posted in the original post. Yeah either of those will work although not sure why the 2nd one looks diff. The first link looks exactly how my 3 sets of TBI injectors i have laying around in my garage. Trying to find a high flow rate injector in the junkyard is tough after 25-30years, the color coding is completely gone!
