You might want to do some measuring. I think the frame width is different between 1500 & 2500 causing a little more work? I haven't given up on that idea, I just don't have the parts in front of me to try. I hope you figure it out first!

Yes, all the same tricks apply and good luck with your build. I've got a lot of local buddies trying to talk me into doing a SAS & adding a transfer case to mine right now. I think that would be hard on my 30mpg though!

Very nice work here. Are you running higher boost with the turned up pump? Stock compression? High flow injectors? Also, is it the same turbo as the 5.9? My cousin has considered a 8.3 turbo on his 5.9, little more airflow, I don't know if you can do the same with the 3.9 to 5.9.

I don't have many good pics of the mounts. The process of fabbing my mounts was no different than fabbing any type of mount. You just start by welding plates to the frame so the hydraulic mounts have a place to sit, then bolt plates to the motor and start welding to them to connect to the mounts. The motor was hanging from a hoist and and positioned where I wanted it while I was making the mounts.
Currently, my motor is 100% stock with the exception of the fuel pump being turned up. The turbo is an HC1 wich is the same used on the first generation 5.9s. I do have plans to upgrade it but haven't decided on what exactly I'm going to do. (one bigger one on top of this one or one bigger one instead of this one)

Given the numbers the 6cyl cum ons get I would think that thing should be able to hit 500hp, 1000lb/ft with a bit of work.

I have heard of guys getting over 800hp with these little motors but that will take more money than I am willing to spend right now. I really wanted a p-pumped motor to begin with but they are a lot harder to find and usually draw more money. They did make a 16 valve version and bumped the cubes to 4.5. We have one in a Case skid steer right now but I haven't heard much of anyone putting them in trucks.
