I am looking at buying a 94 f250 it's the turbo diesel IDI 7.3, non-powerstroke. Most of the information I am finding is just about the powerstroke engine. The one I am looking at the guy is asking a little over kbb for it, which may not be a bad deal if it's a solid truck. I don't plan on doing more than just bolt ons with it. I plan to use it for hauling/towing, and just a general work truck, I have no intentions of racing it or trying to make gobs of power. What are your thoughts on reliablity and also what do you think would be a fair price (assuming it's in good to fair shape) on a 94 regular cab, 4x4, auto with 169k on it? Thanks for your input.

I think depending on the condition of the cab, interior, ect...but if its nice...$4-5K.

IDI's are simple, cheap, and easy to work on. Those are there pro's for sure. Heck you can buy all 8 injectors, with return line kit for the price of one powerstroke injector. That said...

They are underpowered. I have to warn everyone asking about this. You can turbo them, and turn up the pump for easy mods. It will be about as good as a lightly modded OBS PSD (94-97 powerstroke).

even if it blue books for around 3k you would still think it would be worth that much?

Also the truck that I am considering is a turbo charged truck, it's just not the Direct injection Powerstroke, it's the IDI turbo diesel. According the FAQs here they come stock with 190hp and 385ft/lbs at the crank. Is this the engine you are saying is underpowered?

I didn't think it would blue book that high. I would pay that much for a nice one. I'm just use to rust free trucks though.

Yes factory they are a little underpowered. You can get
them to run with a mild tuned PSD easily though. They difinatly have a much stronger bottom end than the powerstroke. The powerstroke just has a better platform for mods. Though you can get free hp and tq with a turn of an Allen wrench

Where did you get your ATS turbo?

Bought it used from a guy back up in Oregon. He sells IDI parts, mostly injection parts. He had a few laying around. He rebuilt it for me, and sold it complete for $900. The 093 kit, which is a little better than the factory IDI ATS turbo

looking at differnt sites (kbb and nada) I am finding that kbb says there is a 1500 difference in value of a turbo diesel and a powerstroke diesel, but on the nada site there is only one turbo diesel option, it does not seperate the non powerstroke from the powerstroke. Do you guys think the powerstroke makes a $1500 difference?

I can see the powerstroke increasing the price some....but in all honesty it just comes down to the truck. I've seen IDI's sell for more than powerstrokes...and vis a versa. It just depends on the truck.

Also KBB and Nada arent the best for looking at truck prices, they always seem off. What part of the country are you in?

Everything checked out pretty good last night so I am pretty sure I am going to the the truck with in the next week. Once I get the truck the first mods I want to do are down pipe and a better intercooler. Does anyone make a 3" down pipe for the IDI 7.3 turbo engine? Also I was reading in the powerstroke section that the 6.0 intercooler was a popular upgrade. Does that fit on these truck too? I have read about turning the injection pump up, but I am curious how much this effects the fuel mileage. Any advice is appreciated.:thumb: I want to do minor mods that will not really hurt fuel economy.

I think ATS sells the upgrade for the downpipe/exhaust housing on the intercooler. But I think its like $800. You might want to take it to a muffler shop, tell them to cut the downpipe off at the flange, and then weld a mandrel bent 3" pipe into it. That way you have the stock mounting, but then it goes into a nice round 3" pipe instead of that cobra head downpipe.

I have a 6.0 intercooler sitting at home, though its a custom thing to put it in. Thats why I havent started. Hypermax sells a intercooler kit, but its like $1500.

Turning up the pump wont decrease fuel milage, only your right foot will. If you cruise, you will get the same milage, but at WOT you will be injecting more fuel, therefore your fuel economy will go down some.

I have been reading about the ATS stuff and that is way more than I want to spend for a downpipe. I was hoping you guys knew of something I did not.

I never researched the intercooler thing I just assumed they were factory inntercooled like the powerstrokes....I guess I was wrong:tard:

I start thinking about turning the pump up after I put in an egt gauge. I have one on one of my cars that I was planning on taking out in favor of a wideband 02 gauge. How much of a gain can you expect from just turning your pump up, and everything else is stock?

Yeah they are definatly costly to buy from. That said, I think the best thing to do is do what I said to the stock downpipe. Cut it right at the flange (but leave just enough to weld onto. Then have a muffler shop mandrel bend a 3" pipe to fit exactly like the stock downpipe, weld it together, and put it in. That way all the angles are the same, and it should fit (you will have to clearance your firewall, aka bend it back with something).

Yup, all intercoolers are custom fit except for the hypermax kit which should be complete. ATS use to sell a intercooler kit, but they dropped it.

Diesel's are opposite of gassers, the more fuel you put in, the higher the EGT's. With the stock downpipe (restrictive, higher EGT's), you could probably max the fuel out, but you will have to watch the pyro. I think a good 20-25hp is obtained from turning it up. Not bad at all :thumb:.

Also, turbo diesel's dont really need a muffler as the turbo is good enough at muffling the noise. Therefore, you can straight pipe your truck :thumb:

I'll check around on trying to find someone willing to do the down pipe at a decent price. Even if I could not find a mandrel bent pipe I am guessing a crush bent would still be much better than the smashed stock pipe?

I'll put the intercooler idea on hold then.

Does anyone sell just a 4" exhaust with out a muffler/resanator? I don't mind if it makes it a little louder but I don't want it super loud either.

Also while we are talking about performance it looks like running a larger exposed element air filter is a pretty popular mod too. I know on my cars it does not do a whole lot other than make a cool noise. Are there really gains to be had doing the homemade intake mod?
