Turbo Vs. Motor swap

[Clak_clak_clak92]

Hey guys i got a 92 7.3 F350 i was wondering if i should put a turbo or go to a PSD or Cummins Motor swap can you guys give me your oppinion. Thanks

Well I don't think an IDI can really take on a DI engine for power. I think a 12V Cummins would be an easier swap but that is up to you. Here are some swap links that I hope help you out:

I agree that a 12v Cummins would be an easier swap, go to Fordcummins.com for info. and conversion kits., I have a couple of friends do it with good results. The Powerstroke would be hard with the computer and tons of wiring! It is not cheap to swap, might be cheaper to put a turbo on your 7.3 if it is still a good engine. I have a '94 factory turbo that runs great, and I have owned every diesel Ford has put out including the 6.4, and as far as fast my'94 will out run my 6.4 in a short drag race (1/8 mile). I prefer the '94 to drive over my 6.4. Check everything out and compare the prices and see what looks better to you. It will also matter if you have a standard or an auto for the cummins swap, 5spd. is much easier I hear. Good luck!

Powerstroke,

Thanks for your opinion i have a 5spd crew cab, i see what you mean cost wise, but in power wise wouldnt it be better to get a cummins or there isnt that much of a difference in power between a cummins and turbo

Cost wise, you would come out better adding a turbo kit from banks or hypermax and turning the injector pump up. I'm not sure what kind of power you will see, but I hear the change is dramatic. You can also get modified injector pumps for even more power.

If you go the Cummins route, an early model 12 valve engine (pre '94) would be the easiest swap, but power won't be much more than what you have now. The potential is a little better, though. If you want big power, a later model 12 valve would be the way to go, but the swap will be more involved because of the electronic engine controls.

A Powerstroke swap would be about the same as a later model Cummins as far as the actual swap. Power potential, for the money, is less than a Cummins. If you do the late Cummins swap or the powerstroke swap, you would be best to buy a complete donor truck for parts. The expense will be pretty hefty.

Good Luck!

My grandfather has an old 6.9 with a turbo and it runs pretty strong. If youre just using this to tow I would just go with the turbo.

I had a 6.9 that I turned up and put an exhaust on that could out run and pull with the early 12 valve cummins and it was not turboed. My '94 factory turbo that I have now pulls better than my friends '02 24 valve cummins, they are both stock, and it gets way better milage than the cummins pulling a big trailer(40' flat bed). I am not a cummins fan what so ever, I know they are good engines and they can be turned way up, but they leak oil really bad and I just don't like the way they feel. My '94 feels like a gas engine, super fast, and I have not even turned it up yet! I think a good turbo and exhaust would be much cheaper with good results!
