E Code injectors
Hello All - I have a 1989 7.3 IDI with 122k miles on it. And I think its time for new injectors. Fuel mileage is getting crappy when towing and power is down. My question is, I got a set of injectors from a 1993 7.3IDI non turbo. They are brand new and I got them for free. I was told injectors changed in 1992.5. Can I use them, whats the differance.
thanks Guys

They were designed to be used only with the 92.5 engine and corresponding IP....
This explains it.......
There are three different injectors used in 6.9 & 7.3L engines - one for the 1984-1992 6.9's & 7.3's, one for the 1992 1/2 - 1994 IDI engines that Navistar referred to as the "P&E" (performance & emissions) engines and one for the 1994 IDI turbocharged engines.
In reviewing the drawings I see that in addition to to different nozzle opening pressure for the injectors, there are a number of differences between the nozzles including:
different pintle diameters, pintle bore clearance, valve overlap length,valve extension etc. all which result in different valve lift vs flow characteristics and therefore result in the different injectors for the different engine applications."
