'94 IDI Turbo IP/inj?

[nberchem]

Do these engines have the same IP and injectors as the non-turbo 7.3?

Thanks,
Nick

[94_turbo]

no--5069, or 5070 on the side of the ip---and g stamped on one of the side flats of the injector

[nberchem]

Could you elaborate?

Thanks,
Nick

Different year of engine build , turbo or non turbo different IP......performance and emmissions engines.

You say this is a turbo, the turbo injectors are code "G" and the pump is a 5070 (auto) and the non turbo are "E" injectors, and a 5013 (auto) pump.
92.5 E injectors and 5013 IP
94 TD G injectors and 5070 IP

No they are not the same

[cgraham]

How much more power would you expect to get with a turbo pump and G code injectors? Cause my factory turbo 5 speed hauls butt compared to my 87 with a Banks turbo and auto trans.

[cdnsarguy]

Sorry I can't help there..........someone else must answer that one.

[7.3L F-250]

if it came from the factory with a turbo then it has the turbo injection pump and injectors

[94_turbo]

the pump that had 5069 on it was the 5 speed pump then---but still g code injectors-------

[nberchem]

Thanks for the replys. The IP and inj's aren't the same, but can they be interchanged?

You can install any IP or injector that will fit....... but they may NOT work as designed. Different break pressures in the injectors ie 1850 vs 2050 will cause a timing change that would cause problems......

I searched for this info in my files...............

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."

What I'm wondering is if I put the IP off the 94 turbo (5 speed) onto the 87 will it give me any more power?

no it wont work because its a injection pump for a standard not a automatic which means your C6 will not shift

[cgraham]

I don't care, I won't have a C6 for too much longer. Autos suck bigtime.

[7.3L F-250]

then yes it will work but as for more horsepower i wouldnt count on it but it might

[nberchem]

Thanks, Ya, I kinda figured it wouldn't be that simple. Could the IP and inj's of an NA be modified/rebuilt to the turbo specs?
