Yup...how odd I wonder why 95 was the only year to have those and had the highest flow...
So I was right about the 95's with the chart I posted earlier (same as the dodges BTW)... I though only the 95 5.9's came with those injectors though...either that of the pcm throttles them down to the 18.x lb flow yours actually uses... The thing is again like I mentioned earlier the stock injectors were timed to fire on the back of the hot valve to turn it to a vapor just as the valve opened... All the pros who I spoke to about this said you have to retard your fuel syc with a machine and by turning the distributer to get optimal timing for these new atomized spray injectors vs the stream ones...
So they should have worked in your just like they should have in mine.... Wonder why they didnt?... I still have mine sitting here along with like three sets of 19-20lb ones to test for the seller I bought them from... he said he had never sold the 703's for a magnum engine before ..only the older 2nd gen injectors modded for 4 hole spray flow...
Here's a post from a guy named HankL who really researched his answers...Notice he mentions the computer must be changed or reprogrammed...
"I read the following from the Q&A section of the official Chrysler publication 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
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)
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
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.
For Junkyard hunting
here is a very large list of injectors used in past engines:
