Hi:


I took the fuel Injectors out of my GTA and they are FORD. Why somebody put FORD injectors in a GM GTA? I'm Lost.


Is their any benefit from this?
Should I swap back to a GM LIke Injectors?


What Injectors should I use if I decide to replace them?

Bosch 3s are from ford applications. The older blue and yellow tops have the same impedance as Bosch . If the engine was running well with them keep them. Southbay fuel injectors sells 22#hr injectors for your 350 tpi.

 

 

It was not running good. I don't know if the injector are the cause but I sent them today to SouthBay to have them check.


Thanks for the info.

 

Those are big injectors 30#hr I think

 

They can be tuned for but unless you have a built 383 there isn’t a need for a injector that large. I bet you were running extremely rich. You might want to replace your o2 sensor too.

 

What would you sugest?
Replace them or tune for them (If they pass the test)

 

That might also explain why I had to replace the catalytic converter.

 

I would put your money in replacing them. If you have them cleaned and flow tested that might run $10 -$15 or so each. Refurbished 22#her are $166. If you mention your a tgo member I think you get a 5-10% discount.

That would definitely kill the catalytic converter

 

OK I agree with you.


I already talk with South Bay and they are willing to do it any way I like.


If I'm replacing them what would you suggest I get? Remember that I don't min sending you my chip to be tune for them if your suggestion required it.

 

22lb Bosch D3 Corvette Camaro Firebird TPI

They Have thise for $165

 

24lb 350 / 5.7 Bosch D3 Fuel Injectors Camaro
They Have these for $170

 

The tuning would be a multiple tune process requiring you to datalog.
If you buy the equipment I would assist. You would need to get moates.net
G1 a few sst27sf512 eeproms a burn 2 and the extreme aldl with cable. This would cost you a few hundred dollars and your ecm is problematic to connect to just the nature of the 1227165 ecm.
I would look into there fuel rail o-ring kit and gasket kit if you can’t get these locally.

 

I would get the stock size 22#hr

 

27lb Bosch D3 Corvette Camaro Firebird TPi
They Have These for $171

 

It sound a litter involve as of Know.
So I think I'll go with the 22 to keep factory


What do you think?

 

I'll probably want to sent you the ship anyway to make Shure nobody have work it before.


I found another computer I had save from other 1989 GTA so I can sent you the one for the current GTA so you can check that it still Stock.

 

It would be the easiest for you. The Bosch 3s do have a audible clicking sound to them bye design or sound transfer to the intake manifold but they work well good value for the price.

 

You could tell if the chip has been modified if the silver sticker is intacted.
To modify it the silver sticker needs to come off so it can be ultraviolet erased. Or a piggy back adapter needs to be installed like the moates.net g1.

 

This thread is stupid. The is nothing wrong with Ford supplied Bosch injectors. Even though they are GEN 1, they work.

The issue is not the injectors but the tune. Get the tune set up for those injectors and the engine will run great.

And yes, the Ford/Bosch red tops are basically a 30 lb/hr injector. Unless tuned for they won't run worth damn.

RBob.

 

Just because an injector is stamped Ford means absolutely nothing. They are made by bosch. Injectors are used in multiple applications. As long as they have the same flow rate and resistance most injectors can be used in any application.

 

It was not my intention to make a stupid question. I didn't know that Buch made injectors for all cars and keep the Ford Logo.

 

I believe this is not stock ether HiperTec




My current GTA Ship




Current GTA Chip Side View




Current GTA Inside View




Old GTA Ship

The apyu is stock for your 89 350 automatic 3.27 axle ratio.
The apyu looks to be all stock not modified.
There was a update but I don’t think there was any running issues with the apyu. The newer calibration is aujm.


The Hypertech is a aftermarket but would not be programmed to account for the 30#hr injectors.

What About the OLD GTA Ship? is that Stock?

 

Yes the blue covered memcal looks stock.

 

For the record, my 89 Iroc, 5.7L with 2.77 ran GREAT, and even passed NC emissions YEARS ago with 24# Bosch/Ford injectors and the Hypertech chip.

Agree that Bosch/Ford makes no difference.
Agree that flow rate and matching tune matters.

Hypertech is basically stock. -at least for the sake of this convo

All things being equal, I'd get 22/24/stock flow injectors BEFORE tuning a stock engine to run on 30 pound injectors. -although I DO agree it would run just fine if you did. -That being said, if tuning is something you're interested in, then sure, might as well keep the 30 pounders and jump in. ....but if the intent to to simply keep a stock engine running right.....I'd swap injectors. The more things you keep stock the better, for you or anyone else who may have this car.

 

when I get my 22# injectors will start with the OLD GTA Stock.

Any thing you advice I replace before trying the injectors beside the O2 Sensor?

 

Nothing else I can think of. Should run much better with the correct injectors.

 

Nice Package


Nice clean new Injectors

Got my new Injectors Today

 

Thanks Julie

 

Just waiting on the new O2 Sensor to put it all back together.

 

My pleasure sir! Keep us posted on how they work out

 

Did you get it back together ? How does it run ?
