Ok I have a 96 ram with 176000 miles, no major problems, just tune ups and oil changes. The downside my injectors are going bad and whats the best brand to go with for replacement? The truck is stock no mods at all. I used the search and only found people wanting performance upgrades.Thanks.

 

the dealer should stock the oem injectors. i think they are 19 lbs. might cost about 300.00 for the 8 of them. as for an injector upgrade you wont need it. unless you are going throught the whole system upgraging fuel pump and regulator.

Thanks I appreciate the help.

 

From the DML and Shane Mosley:

"I read the following from the Q&A section of the April 2001 Mopar
Performance News:


Q(5) I'm working on a fuel-injected combination and my dyno program
shows I could benefit from more injector delivery. What can you tell me
about flow rates of the injectors in your catalog? Also, if you have
the factory injector rates would be very helpful.


A(5) You should step up the injectors in something like only 25 percent
increments. The production V-8 is 24 - the MPP package is 30! Remember
that you must change the computer if you change the injectors; at the
least, it must be reprogrammed with the new injector values. Injector
rates are not as easy as one might think, but they go something like
this:

Engine Years Flow rate in lb/hr
Neon ( All) 23.9
2.5 Magnum 91-95 17.4
2.5 Magnum 96-01 23.2
4.0 Jeep 91-95 21.4 (Equivalent to Lucas 5207013 )
4.0 Jeep 96-01 23.2 (Equivalent to Lucas 5208005 )
5.2 Magnum 92-95 18.2
5.2 Magnum 96-01 23.2
5.9 Magnum 93-95 24.5
5.9 Magnum 96-01 23.2 (Seimens/Chrysler P/N 53030778)

---end quote---

Note that about 1996,
when the engine PCM computers went to the OBD-II standard,
all the Dodge fuel injectors went to a 'common calibration' of 23.2 lb/hour.

There is another article about different makes of fuel injectors I
read at:

http://web.archive.org/web/200106101...ectioninfo.htm

If you have a modified 1996+ Magnum engine and you feel you need to 'bump up'
the fuel injectors just a bit, the model year 1993-1995 5.9V8 fuel injectors
are about 6% larger at 24.5 versus 23.2, and Neon injectors are 3% bigger.
Another option is the 25.3 lb/hr:
Bosch PN F1TE-D5A (280 150 947)
{255 cc/min}
Originally used on Ford 5.0L 93-95,
Ford trucks 7.5L 91-97

 

I never would have thought that the computer would react to a slight change in lb/hr. In my ignorance I thought it would adjust itself. I am glad you posted this because the injectors I was lookng at were 20-25 lb/hr depending on manufactuerer. For myself stock is a good thing, but I refuse to go to the dealer here where I live because they SWEAR that Dodge never made a GAS 5.9...........Looks like I am shopping on the internet

 

At part throttle
the PCM computer can adjust fuel injector pulse time using memories inside the computer that Dodge calls adjusted fuel factor (AFF) and added adjusted fuel factor (AAF). Other manufacturers call these short term and long term fuel trim. The PCM computer reads the O2 sensor and gradually stores these adjustments, which are necessary both for the wear of fuel injectors, and for the way gasoline varies in its heat content.

But at wide open throttle,
where you are asking for maximum power
this does not happen.
At wide open throttle the PCM computer quits looking at the O2 sensor and begins using stored fuel injector pulse information from its factory set tables. Here fuel injector size does matter, and is not adjusted for with any short or long term values.

Since you have a 1996 with the fuel injectors of the 'common calibration' of 23.2 lbs/hr it should be no problem to find injectors, either new, or from a low mileage 2.5/4.0/5.2/5.9 Chrysler engine from a salvage yard.

Be aware that in later years the electrical plug changed, somewhere around 1998-1999
