93 f-700 CTD

[vhainesxx]

Does anybody out there know if a ctd thats in a 93 ford f-700 heavy duty has any different characteristics or built any differently than than a CTD thats comes in a 93 dodge truck?

Doubt it be a "B" series but then again they put the B into 84 pass school buses!!!!

It says on it B series 5. 9 cummins turbo diesel and it looks the same. I was just wondering if the specs were different or if the modifying capabilities were the same

 

[Greenleaf]

Yah Boy.



It probably has different pump specs but all in all the pump modifications would be the same.

Are you looking to buy the engine, the truck or both??

 

[lil red cummins]

the f700 i work on is a B series with the typical looking bosch pump. the fuel filter and pusher pump system are different. the turbo is way way bigger and non wastegated. the exhaust manifold is different also.



it is backed by an allison auto.



nicest truck i have ever driven or worked on in this size range.

Hey Mysteryman, just out of curiosity what's different about the head? We have a lot of 5. 9s at work in buses and things, and they all look the same save for some of the bolt-on stuff like exh. manifold, air inlet etc. I would think you could just bolt on Dodge peripherals and go to town. As far as power goes, I don't think that'd be an issue going by what some of these guys here are getting out of their trucks. Just curious, 'cause information is good ya know.

That is an interesting question. What is different about the cylinder head that sets it up for more power, and what are the differences in the turbo specs wise, is the different turbo a good or a bad thing. This is information I need because I own the truck and I need some helpful hints from people that know what goes on under the hood of those "darn" fords.

 

[lil red cummins]

i don't believe they have more power. the one i work on is rated at around 225-250 HP. i don't remember exactly and i am not able to get a look at the truck right now.

[mysteryman]

well the first gen Dodge's are rated at 160 hp

Oil pan will be different too . . .

Just wondering if the stage 1,2,3,and performance upgrade suggestions that pastor Bob mentioned in the earlier thread will apply to this engine, and if so, when you get to the part of tweaking the injector pump, what are the specs to safely do this if this a different injection pump or the specs are different?

allison

Also can anybody tell me how strong the Allison At542 4 speed auto is, as far adding a little hp. Will it hold up to it? I believe the Allison 542 is the predecessor to the 545 which came out later as a new designation but basically the same transmission(At least thats what they told me on the Allison Tech line) I figure somebody here will know.

Just wondering if the stage 1,2,3,and performance upgrade suggestions that pastor Bob mentioned in the earlier thread will apply to this engine,

I think just about all would apply. An exception might be injectors and the nominal amount of HP they would add... . so you should check what you have and see if the part number is the same or different from a "typical" stock 1st gen and go from there.

But you should probably get an answer to your transmission question before you play.

Our 545 are now old, outdated units. They have fased them out in favor of the 2000 series, which are now outdated... ... .....



The 545 is behind our 190 hp Cummins "B" engines 65 and 72 pass buses. They work very well. Too well in fact. So well that they "had" to stop production and make something that isn't nearly as durable and trouble free. But hey, that's progress, right?



Electric lift pumps come to mind... ..... roll eyes



So far my modified bus engine, Cummins "B", has been pushing power through a (high mileage) 545 but I have yet to dyno. I'm trying to find a way to get the bus off campus long enough to drive to town,dyno it, and drive back during my lunch break.



Could say I'm "test driving" the bus... ... ... ... ... . ?????
