Greetings folks!

I thank everyone in advance for the knowledge you are about to share with little 'ole me. I have tried to search this but to no avail. Maybe there is a short between the chair and the keyboard....


I have an inside line on a very good looking 1997 F250 with a 7.5L Gas burning engine. I want a diesel, but this truck is priced as such to make me look into a 7.3PSD swap. Anyone with experience? What would you guess i would be putting into this venture in terms of cash? and time? and eventual troubles?


THANKS!!!!!

 

Welcome yergi!

I'm sure this will be a fairly easy swap in my opinion, since these trucks are simple, and the engine is easy to access. Also it will be easy to mate the diesel to the trans since you have either a e40d or a zf5. Check out http://www.painlessperformance.com/ for all the wiring trouble you may have. Your biggest expense will probably getting a power stroke engine.

Someone will chime in soon who knows more about these trucks and these engines than I do.

I wouldn't do it! the only way it would be cost effect is if you had a wrecked diesel truck with all the parts your need. There is nothing in the gas truck that can be used other than the frame and the body. You will need a core support, radiator, engine, engine compartment harness, PCM, IDM, dash wiring, cluster, transmission (gas and diesel trans are different), fuel tank sending units, and exhuast. All in all you will spend alot more money on parts then you will a complete truck.

 

ya, like TJ said, the computers, transmitions and everything are different. the E4OD in a gas shifts at totally different points. they have different valve bodies in the trans and everything. not worth it to me. if you dont drive alot, and i mean alot then at the right price i'd buy that 460 and enjoy the grab you by the seat of the pants acceleration. the 460 won't hold quite as good on hills, but man they are mean.

 

On the trannies the entire case is different. it bolts to the engine with a different bolt pattern than the gas trannies.

 

Wouldn't you have to swap all the fuel lines and fuel tanks over as well? TJ and 2 stroke are right, definitely more trouble than it's worth.

 

Fuel lines would be fine but the fuel tank sending units are different. tanks would be fine as well.

 

my bad i thought the transes were the same, sorry

 

A cummins 12 valve swap would be much easier then a powerstroke. The Cummins 12 valves only need 3 wires to run. Power, Start and ground.

 

I thought the strokes had poly tanks, while the gas rigs were steel... good to know.

 

You could do a 7.3 litre IDI (NON PowerStroke) swap and it would be a bit easier, you will still need to change out the Radiator and core support and of course the main running gear. I worked with my neighbor to swap his out, still a bit of a pain... but we did it...

 

I looking at trading my 7.5 250 ext cab long bed for 7.3 350 4 door long bed any suggestions as to why I shouldn't or should?

 

Nope. You're wrong. The bolt patterns are different between a 7.5L and a 7.3L. You can't use the same transmission.
That's not relevant. The transmission shifts when the PCM tells it to shift. The shift points have nothing to do with the transmission itself. But bolting a gas transmission to a diesel engine is a big problem.

 

old thread.

Question on this topic though, what would the value be of a gas truck converted to powerstroke be, compared to one that was originally a diesel out of curiosity ?

 

Take book and divide by 2.

IF you do a show-quality conversion you might find a buyer who is willing to pay extra. But they won't, they'll just keep saying it's a *******ized, compromised conversion, and they will wear you down like cheap tires in a heat wave.....
