Hello all i am new to the site and i have been bitten by the Diesel BUG. I drove my dads 2007 Dodge 2500 with a cummings diesel and now i want one in my truck. I have been visting the fordcummings.com webpage but i really need more info. For instance Will my Stock ford tranny hold up to the Diesel Engine? Will My F150 Need different springs in the front for the heavyier engine ? also will my Transfer case be able to hold up to the Diesel. The website doesn't really answer the questions for me clear enough so after finding this site i am just thrilled. What i understand is that the 94-98 12 Valve Cummings is the best fit for my application and requirments. is this true? and why or why not? thanks so much for taking your time to answer my questions and have a good day.
Here is a insert that i read from the website fordcummings.com to help choose the appropreiate engine.

Picking a 5.9 Cummins Engine


Generally, the older Ford trucks get the Cummins older engines and the newer trucks get the newer engines; however, there are several newer trucks with older transplants and plenty of older trucks with newer Cummins engines. Some combinations are more involved than others, however, in the end it is simply a matter of preference. The 5.9 Cummins engines is fairly universal as far as transmission mounting, if a tranny fits one engine, it will fit another (providing the proper adapter plate is used). For states with emissions concerns, the general rule is to go with a Cummins engine of the same year as, or newer than, the Ford truck.



Cummins engine swap preferences to consider are fuel economy, horse power and torque, weather the engine is manually or electronically controlled, noise level, ease of installation, and purchase price.



The 12 Valve
The 89-93 5.9 Cummins engine is readily available, inexpensive, gets the best fuel economy, and has decent torque. It utilizes the Bosch VE rotary pump which can be adjusted to achieve a little more horse power (we can help you do this). This Cummins engine can aslo take an upgrade set of injectors as well as a different turbo housing to gain yet a little more diesel performance. The 89-91½ Cummins engine is non-intercooled (but can be intercooled when doing the Cummins engine swap). 91½ and newer are all intercooled to begin with.



The 94-98 5.9 Cummins engine offers a bit better diesel performance, as well as, great fuel economy. It has the Bosch P7100 inline manual fuel injection pump which produces 160-215HP stock. With this pump, one can easily add 15-95hp by installing a simple fuel plate. We can also sell you a pump that is already turned way up if you are looking for some intense diesel performance. There are also several other horse power upgrades that can be done to these engines with out totally sacrificing fuel economy or reliability.



*Both the rotary Bosche VE and the inline P7100 are very reliable.

Unhh, did you try doing a little reading/lurking asking smaller shorter questions about things you can't seem to find? Takes a little time but you end up learning a lot more than what you started to and you don't get on every ones' nerves as bad. Hang out - it's a fun place.;)

Will My F150 Need different springs in the front for the heavyier engine ?
Age and condition of your springs are a big factor as they are probably marginal to begin with.
also will my Transfer case be able to hold up to the Diesel. The website doesn't really answer the questions for me clear enough so after finding this site i am just thrilled.
You did not say which transmission you intend on using. Most economically minded folks simply swap in the entire Dodge engine, transmission, and transfer case because it's generally reliable and factory parts are readily available. The aftermarket stuff adds dollars really quick.

What i understand is that the 94-98 12 Valve Cummings is the best fit for my application and requirments. is this true? and why or why not? thanks so much for taking your time to answer my questions and have a good day.

Cost and availability usually end up the deciding factors for a swap and then preference follows your selection. Do you have unlimited resource$ and availabilities?

I'm going with F250 springs in my F150 2wd. F350 are really stiff. Also going to use a harmonic damper. Using the Ford ZF 5 speed from 88 250. There was one on Flebay that no one bid on for 4wd. Was surprised.

This swap can be pretty straight forward, swap the front and rear axles with ones that a 94 f250 with a diesel would have, put 3/4 springs in the front, you can easily find mounts for the engine and don't use the f150 transmission, gasser transmissions can't hold up to the torque, hell, the dodge transmissions from 94-02 can't hold up lol, get a 94-98 12 valve, grind your fuel plate, put your timing to 16 degrees, you'll get excellent mileage and awesome power but be sure to get a manual tranny, preferably 6spd but 5spd is ok.

No problem, I love when I can get a great deal of information, when I did my cummins cucv swap everyone wanted pics before and wanted to know performance mods instead of giving my advice, sure I got advice but definitely not as much as I needed. How are you progressing with this swap.
