Best Diesel Truck Engine

[Stalkin Prey]

I apologize if this is a long one guys. This is based off my experience and opinion. I own a 07 dodge 2500 with 5.9 Cummings with 48re auto trans. Before I bought it I researched a ton and decided that the last year of the 5.9 was the way to go. Ya everyone talks smack about the 48re. I'm extremely hard on everything but I take care maintenance wise as well. I've owned my truck for 4 yrs. It had 6" lift 37x13.5 MT's when I bought it. Everyone needs to know that lifted trucks with big tires will wear out parts faster then stock ( wheel bearings, ball joints, u-joints etc) I knew this going in as it's standard with lifted rigs. That being said my truck has been a beast. When I bought it the exhaust was done already 4" down pipe-5" straight pipe. It had boost, pyro, trans temp pillar gauges. I've pulled lots of mountain passes and in heavy traffic 10k plus lbs. With that set up my stock turbo would easily boost 40lbs, egt's would run hot though. Even in tow haul mode. Not mashing on the gas guys (conservative tower) no one needs to be hauling loads as fast as they can. For example up a steep grade boost would be 30lbs +, egt's would start creeping 1350-1400, hot day trans 180-190. Installed an AEM brute force intake which helped a little. After 4 yrs things started to wear out which I expected. I've replaced wheel bearings a couple times, ball joints, upgraded u-joints (due to lift and power), steering box with pitman arm, brakes,rotors and calipers all the way around. Those are normal wear and tear parts in my opinion. Now the hard on your wallet stuff. Edge juice with attitude with cts2 monitor, Great tuner and love the monitor. That being said it pushes everything beyond its limits. Even with setting limits and alarms it exceeds what's some parts can handle. Pushed my turbo to hard for too long so it started to go out. Installed an industrial injection silver bullet phatshaft turbo. Amazing turbo for towing. Lowered egt's over 200deg and really increased my performance. With increased power I started over exceeding my trans further than just with the tuner. Then I built the trans. All billet internals, triple  disk tc, HD valve body, external cooling system. Basically as bulletproof as I can get it. This truck has been amazing and I won't buy a newer one with all the dpf and egr headaches. Just everyone realize that once you start adding this and that it will affect other things. I knew this going into it and when something wore out I did not replace with stock components. If you over exceed stock you will need better parts. These trucks are amazing. It's my work horse. Sorry for long post guys

 :yeah:You are right.  My truck is very similar to yours.  I did an Austin Tater custom turbo.  It is a stock machined and built to 62/65/13 specs.  Spools almost exactly like a stocker.  Pulls great, drives great, boosts a lot.  But your II phatty will cool a little more.  My trans still good but I have to be carefull.  I cannot floor it or it would let go.  Torque converter cant take it.  ARP studs would allow 45-50psi boost which turbo is capable of.  What I do know is I will run down a new Manual cummins towing up hill-Done it.  It is about $ in the end.  Trans is next on the list maybe but its gonna be $.  Also don't skimp on flexplate-its crap.  Replace it too.  Love my Edge, features are priceless.  Other tunes may produce better power but as a package deal its pretty darn good.  I have also done Steer box, pitman, brakes, ball joints, u joints, tie rods and sway bar links are junk.   12-14 towing and 18-20mpg empty.  Love it.

Yes sir. Great power house. Trans was a lot but it made a huge difference.

I have the early 07 Duramax and love it. The Duramax Allison combo is hard to beat, too bad they screwed them up with all the emissions crap. I have a lot of towing miles on mine and it has been nearly flawless. I put my side by side in the back and hitch up the 27' travel trailer and it does great. I've towed all over Washington, Oregon, Idaho, Nevada, Montana, Colorado and Wyoming.  I don't see me ever parting with it.

Do yourself a favor and quit looking at it.

Pops got a 2017 F250 diesel with all the bells n whistles,  that thing is nice.

I drive a 1995 with 12v 47rh transmission, 300k miles.   Still goes good but I might need to address the transmission if I start selling hay again
