okay, right now i have a 1994 F-250 4x4. it currently has an IDI Turbo Diesel, but i am changing that. what i am wanting to do is get a PSD, put a 7.3L IDI front cover on it, a fuel pump, lines and then get custom made sleeves for different injectors so i can make a PSD mechanical! what i need to know is how big a powerstroke injector is, so i know about what to replace it with. so is there any way i can get the dimensions of one of the injectors? and possibly a picture of the sleeve they fit in? i cant find this stuff anywhere on the internet.<!-- / message --><!-- no sigs except when logged in -->
I'm not sure what dimentions you need, the actual size (inches) or the amount of fuel they can deliver? Pretty sure all years are the same physical size, but, there are a few different injector fuel delivery rates.
Has this been done b4? or are you that ambitious.
Is there some advantage to a mechanical system vs electrical? Just curious.
PSD injectors are about eight inches long with a maximum diameter of about 2.5"
You will never find a picture of a sleeve for that purpose as none exist.
You'd be better off staying with the high compression IDI block. I's be surprised if you could even get a PSD to light off with those tiny little mechanical injectors dripping into it. PSD compression ratio is only about 17.5:1
That swap would serve no purpose as far as i can see. the reason the powerstroke has more power is becasue of all the eletronics working together to get the right amount of fuel into the cylinders. i would spend the money to add gadgets to your idi rather than mess with the powerstroke just to turn it into a direct injection mechanical engine.
I dont want to rain on anyones parade, nor do i want to sound like a know it all because i really appreciate the input and all the help. First, a powerstroke is so powerful because of the method of fuel delivery, not the electronics...the mechanical system would be easier/cheaper to repair, troubleshoot, and hop up (plus no menus or questions to go thru to get more fuel!). i want to know the dimensions because i am thinking of using something like caterpillar 3208 injectors and injection pump, but i dont want something physically too big. Thanks cookie 88 for the sizes, i did forget to specify what dimensions i needed, but i am not worried about the fuel delivery as i know people that work at columbus diesel and other similar places. the little IDI injectors would never work either due to the sheer size differences in the injectors. the mechanical direct injection isnt all i am doing, however it is the key point of my swap. as far as i can tell it has never been tried before, but everyone around me has either programmed their 'strokes or dropped a cummins in its place...this should be different not to mention, it should actually be a little cheaper than doing a cummins swap.
aah, cool. i wonder what motor that was...thanks, thats a handy bit of info. i didnt learn that one in school. the heui injector is exactly what i am running from here, they are expensive, gutless, and overall just a pain in the ***. what were they thinking!?!?
blucollar your ambitious and creative and if you can make it work i would give you a thumbs up but what your are talking will cost you alot of money in custom machine and injection work.
the 3208 is a much bigger engine that will burn way more fuel than a hybrid powerstroke like you are trying to figure out. i just can't see why you would want to do this other than its original but you must have alot of time and money on your hands
i will try to get the engine model you all are talking about with the cat motor. i worked on one a few weeks ago. i think the heui setup was actually cat's design then they sold it to IH from what i understand.
one cat engine that is heui is a 3126. its a inline 6 with the same type of fuel system a power stroke has.
also blucollar for dimensions for the injectors i think you may want to get the dimensions for the injector sleeve rather than the injector itself. if you really are going to try this i would build a sleeve that has the same OD dimentions as the stock injector sleeve then machine the ID to what ever injector you try to use.
thanks a lot tjbeggs for the help. your sleeve idea may work better than my original idea. i have heard that a 3208 fuel pump only max's out @ 400 cfm of fuel, not sure if thats true or even what it is stock, but i also plan to have twin turbos cross flowing to each head to aid in the complete combustion of fuel. the injectors and sleeves are the only thing i am really hung up on right now because i dont know for sure what to run or what i can run. i do have a few connections for the turbos and the pump, front cover, ect. the only thing that will cost an arm and a leg is the injectors and the actual engine. the machine work for the sleeves will be about $300 per bank ($600 total) which i think is pretty reasonable for what they do. anyway, thank you for the advice!

Without the electronics you leave out tuneability. There are strageties used to control many factors. Sure, you can do it, but it won't be as efficient.
Cat's 7.2L (3126E) uses the same injectors as International's T444E, DT466, and DT530
I think all of Cat's ACERT engines use the same HUEI injectors.
The way it was explained to me the HUEI injector was not only a joint venture between Cat and International, the design team was working in the International engine plant. Evidently upon completion the Cat team snuck out the back door and filed a pattent in one of the worst examples of back door engineering ever.
Can't confirm that of course......just recounting one old man's story.
