Injector info from old posts
It is likely your 3.9 has the common calibration injector too.

begin quote:

"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

For Junkyard hunting
here is a very large list of injectors used in past engines:
