Hey guys. New to the forum. Been reading posts from this site for quite some time, and edumacated myself to a decent extent. But now I think im ready for some interaction with the Competition Diesel gang. Well, I don't own a diesel, but im ready to learn more on doing a swap. I own a 2001 Dodge Ram 1500 2WD with the 5.9L 360 Magnum. Im wanting to do a Cummins swap, and have read about both the 6BT and 4BT. Now, my hardest decisions so far is which one is right for me. I want to make 400 HP, but I want it to be reliable, and I am curious how mileage is affected at this power level? I am a half ton, so I read ups and downs of swaps into half ton frames. I don't mind making a beefier suspension, but im still confused on frame strength at higher power levels. I want to retain 2WD, so is it just a swap of springs, or do they have different control arms? And lastly I want to keep a half ton image, so I would like to keep 5 lug wheels, etc. If none of this can be done, please let me know. Main reason I don't want a bigger pickup with a cummins already in it is I want something unique that gets decent mileage, at least better than my gasser. ANY info is appreciated and i hope some of my questions can be answered...nicely thanks CD community!
