dodge gas to diesel swap

This imo is one of the easier swaps. Dodge has done most of the work for you. I drive a 1989 dodge Ram Charger with a cummis 4BTA and 518 transmission. I have driven it for 3 and a half years put 120,000 miles on it. There were very few modifications. The truck actually weigh 100 pounds less than stock. Good Luck

Do it, you wont be sorry!!! Look in the database, several have already done it and its a good fit! I swapped a 4bt into a jeep 4 years ago and I dont regret it for a mimute. 25mpg and all the torque I need!

buying a 2500 already fitted with a cummins would be the easiest deal, but if you're seeking for the fun factor of a swap go ahead... btw among other options than the cummins 4bt and 6bt, some perkins engines such as the 4-236 and 6-354 would be also easy to bolt in...

Could you keep the stock trans I heard some one say the gas and diesel transmission are not interchangeable

The Dodge diesel transmissions have a different bolt pattern on the bellhousing interface.

p.s. Did you notice that this thread is over 10 years old?

Ok if that's the only difference then perhaps the correct plate can solve it or a bell housing swap. I didn't know it was 10 years old but I still got a response so I guess age doesn't matter on this one

The gas transmission could be adapted to the Cummins but the shift points will not be correct for a diesel. You'd need a SAE 3 adapter and flywheel on the Cummins which is fairly common and an adapter from Phoenix Casting and Machining. That would work with a TF727 or the 46RH (A518). Their part number is 26-02006. No idea of what the price is.
