Swap/Conversion 5.9
Well I cannot bring myself to spend 50K on a new diesel. I bought a 94 F250 turbo 7.3 to satisfy my interest. The single cab has been fun but I want more power so I ordered a 5.9 Cummins conversion manual into Ford trucks. My theory is to buy a 5.9 and transmission instead of a new truck. Anyone have the swap experience they want to share?

yeah but they will understand one day, haha. An engine that was designed to last longer, be more powerful and outperform 8 cylinder diesels. That and it is cheap as hell to do mods, parts are more accessible etc etc. Doing a stroke swap into an idi is like getting another wife, all you get is more complaining and it costs you twice as much. hahah

Not much better then the sound of a properly tuned and piped Diesel i6, bigger the bore the better!
I prefer De-Stroked over Ford Cummins if I was going to buy a kit.
Though thats just from reading ...
However, I ain't wasting no money on a kit or book!

if you go with a isuzu engine, get the newest one you can find. the 2011 has extreme power. you can find a complete truck from some knucklehead who rolled it.

Only problem I have with a 5.9 swap is the gearing. The cummins has loads of bottom end torque. Unless you mess with the IP and crank the rpm's up, factory rpm's is at 2500.
If you have 4:10 gears and a direct drive tranny, it's pretty much topped out less than 60 mph. The ideal combo would be 3:08 gears with 10 speed trans and double overdrive. In a 4x4, low range would be plenty low enough for anything you wanted to do. In high range, floating down the highway 75 mph at 1500 rpm would give some outstanding fuel mileage.

if you are serious about wasting money putting a cummapart in your ford, you should consider the international DT360.
it is a better engine, has much more power stock, and much easier swap into a ford that a cummins is..

So what's so great about that motor? I always heard they were all noise w/ no punch, rattling detroit pieces of boat anchor.

The DT360 is a International (Navistar) motor, not a Detroit, The DT series is an inline 6 wet sleeved motor available in 360 to 570 ci models!
They are good motors, unfortunately they don't have the after market support like the Cummins.
Gearing is exactly why I have yet to stick a Cummins in my 86 ... Else it would be done already.
IMO Wet sleeved motors are far superior to a cast sleeve motor!
