I have a simple question will a set of 24lb injetors off of a 1987 camaro 5.7 tpi fit on my 1989 trans am 5.7 tpi? thanks

 

Yes. But you'll run a bit rich without some prom tuning.

 

For starters, if the injectors are stock on the 87 they are 22lb and NOT 24lbs.

 

no they are not stock they were relpaced with 24lb and have 600 miles on them

 

Try them out and see if the ECM can adjust for the larger injectors. If not then you may require a new chip.

 

what size injectors came on my 1989 trans am gta 5.7 tpi, is it 21 or 22 lbs or something else?, i think ill just look to get the same ones that are stock just need to know before i go looking. thanks

 

These are the only stock injectors used on 3rd gen TPI's all years.
305 TPI = 19#
350 TPI= 22#

 

I have heard that the 89-92 TPI 305 use the #22 but with a lower fuel pressure.

 

You heard wrong. Have your hearing checked and also at the same time check your facts.

 

There is a difference between correcting somebody and being an *******. Maybe the same guy that checks my ears can teach you some respect and some manners.

For the record, here is where I "heard" that little tidbit.

Wow.

While I agree that a higher pressure will produce somewhat of a better spray pattern; GM kicked these TPI's out of the factory with 43.5psi.

 

Not in your lifetime and keep your ******* comments where the sun dose not shine. Now this is correcting someone who is off base with a reply. When you post be sure of the facts and not I heard.

 

I found a set of Accel 21#lb injectors, would i need any modifications after putting them in or just a simple swap? sorry not to familiar with the fuel injection system. Just looking to switch them out and be done with it. thanks

 

You are a rude individual and I wont waste my time or drag myself to your level by fighting with you.

 

They should work,but you maywant to raise the fuel pressure to 45PSI (need a adjustable fuel pressure regulator for this).
