Steve Atkins posted a topic in Dodge-Ram Cummins PowerI recently purchased a 2001 Dodge Ram 2500 to put put a test engine in it. Before the engine swap I wanted to get some base line mileage from the current stock engine. From what I had read and had been told I needed to get my RPMs down in the engines torque range. I am not hauling trailers so the gearing I picked was strictly for millage. First I installing a tall narrow tire 295/70/17. My truck had the stock 4.11 gearing. I was getting 18 MPG HWY at 68 MPH at 2125 RPM. Now that I had some numbers in hand so a professional could do the math. My target was 1800 RPM at 70 MPH. Tom at Reno Driveline and Gear came up with 3.54 gears. I wanted to go with a higher gear but my axels where my limitation. My first run at 1750 RPM took me buy surprise. I got 27.24 MPG (65 MPH). I could hardly believe the results! I then dropped my RPM to 1625 and I got 27.85 MPG (61MPH). 1875 RPM got me 23.2 MPG. (71 MPH). 1775 RPM got me 23.4MPG (68MPH) still not bad. I actually could not have been happier with my results.
Hi, I have a Third Gen 2002 Ram 3500 4x4 with an 8 liter v10 in it. It is a low mileage truck and I have been wanting to convert it into a diesel for a while now. It only has 93,000 miles on it and is well maintained. I was wondering what all I would have to do to convert this truck into a diesel, and how much it would cost. I have been messing around with the idea for a while now, but I now have some free time to change the engine if I have the money. Please help me find about how much it would cost to do this, thank you.
Hello! I'm one of the many 2.5L 4 cylinder Jeep TJ owners who want's more power. I've thought about doing many complicated swaps. I've even thought about putting a 6 cylinder jeep TJ engine in my 2.5L. With the new Cummins R2.8L 4 Cylinder Diesel engines, I really wanted to do the swap. What things would I have to have done? I'd be having a mechanic do the swap of course, but I'm looking into pricing and if it's worth my while. Everybody says to just trade it for the 6 cylinder jeep, or trade and do the swap on the 6 cylinder jeep. I have a lot of money on my 2.5L Jeep in suspension and more, and I don't really want to just get rid of it for half it's price. I've seen people do the swaps before, I just wonder if swapping this new crate engine is possible? Even if I have to buy a new transmission, radiator, computer, etc.
