does the injection pump and injectors dump more fuel than the non turbo injection pump and injectors and can you put the turbo pump and injection on a non turbo 7.3 with out any problem???

 

There are numerous differnces between injectors and IPs which match the different engine(s). You could use any IP and injectors but over/under fueling, incorrect timing etc could/would/may be a problem.

This is info I have saved for a few years......a friend wrote and asked....Stanadyne.

Ok hear we go. I got in touch with Stanadyne Corp. and asked about our injectors, a topic that turns up often! Hear is the scoop.


"Although this is really a question for Navistar, I will provide you with some information.

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 engines that Navisatar referred to as the "P&E" (performance & emissions) engines and one for the 1994 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."

Your 92.5 engine** in your 93 if not a Factory Turbo......should use: E injectors and 5013 IP
