Any Cummins 12 valve guys on here?

My recent battle with my tow rig has left me thinking it's time to finally upgrade the old pig. Truck in question is a 97 Dodge 2500 xtra cab CTD with 151K miles. It has the nv4500 and is 4x4. The motor and drivetrain are untouched except for bigger air filter, intake, intake horn, KDP, and a PacBrake exhaust brake. I have been collecting parts for a massive upgrade since I bought the truck about 8-10 years ago. And am ordering the rest of the needed parts tonight. Wanting to make sure (double, triple check) that I am heading down the correct path.

I am wanting to keep the reliability but wanting a bunch more HP or torque. Real numbers don't really matter as long as I can pull whatever I want, where ever I want, and quickly as I want. MPG doesn't bother me much, some, but not too much.

Here is what I am planning:

Compounds using a S300/S400 (S300G 57/65/12 and a BW S472/83/1.10 T6)
DPS 3 piece exhaust manifold
4" hi-flow exhaust
Headstuds w/ new gaskets
Remove Fuel Plate
Add AFC Live
4K GSK
Adjustable overflow valve
.055 delivery valves
60# valve springs
5x.014 injectors
South Bend Clutch
New inline Pacbrake assembly
New hi pressure boots

So what am I missing? Am I off track?

Parts look good sir. now you have a down stream issue that will rear its ugly head. the 5th gear bearing nut. these like to back off and well crunch!

with your mileage I don't see need to rebuild but I would get in there an fix that issue.

Lots of info on line about it, as well A1 transmission on 8th in Denver is who we use for the work trucks trans rebuilds. there good and will most likely point you in the right Direction.

look forward to see it roll some coal!

Sounds good Aaron. Hope you enjoy the build it's self.
I know you will enjoy the power once you get it turned right.

Another one showed up last night:

The "little" one next to the big one:



For a comparison, the "little" turbo pictured is about the same size as the stock HX35.

Like like it will be fun. Enjoy all that customer Fab to get them to fit. Plumbing degrees needed.
