97 F250HD 7.3 build
hey guys. I finally figured out how to start my build thread. Hopefully I'm putting it the correct place.
97 F250HD 7.3 extended cab full bed auto. This build started in '13 after the old girl struggled towing our 5th wheel from SC to upstate NY. After that trip she got...
Baby swamps from swamps diesel,
TS 6 position chip programmed by swamps,
Banks after-cooler,
4" exhaust

Baby swamps from swamps diesel,
TS 6 position chip programmed by swamps,
Banks after-cooler,
4" exhaust
Air bags in the rear,
Add a leaf helpers in the front (a mistake that was quickly changed to new springs)
Unfortunately the stock transmission couldnt handle the extra power and the torque converter started slipping.
Next round of upgrades lol
Precision Industries torque converter,
Irate Diesel bellowed up pipes (I had the tranny out so that made the install easier)
After about 10k miles worth of pulling 12.5k lbs the transmission gave out but managed to limp home pulling the camper the remaining 200 miles.
Had the transmission done done by a friend of a friend who owns a tranny shop (couldn't tell you what parts he used). Now the tranny is built for heavy towing with my PI TC rebuilt and a new valve body.
The latest upgrade still in process....
Dana 60 front end from a 97 F350 dually. I got the springs, track bar and bracket, pitman arm, drive shaft and all the steering linkages. Pulled the old ttb front end out and installed the new dana 60. My hubs, rotors, and calipers mounted right up with no issues. Just having a hard time locating the correct yoke for the transfer case. I may have found one. I'll know Saturday when I go to pick it up.

I picked up the new transfer case with the correct yoke on Saturday and swapped the yoke to my existing transfer case. After installing the 350 front driveshaft, I now have 4wd again.
i think a turbo upgrade will be next. I'm not a huge fan of watching gauges instead of the road. While I'm towing the 5er it's easy to hit 1300* and have to back off. Or water methanol injection. Anyone have any experience with water meth injection? Money has been tight lately so I'm trying to keep the costs down.

After contacting swamps about a possible turbo upgrade or water meth injection they said I would only be masking another problem. I know I had what I thought was a slight exhaust leak at the turbo up pipe connection so I decided to fix that along with the exhaust pressure sensor tube (I had a plug in the manifold). The 1/2" exhaust stain I saw on top was much larger on the bottom. My boost pressure is still the same but the egt has come down quite a bit. Can't wait to see what it's like with a load on. I can say in hot street mode I would have to back off at about 60-65 because I was hitting 1300+ now I can keep my foot in it till 95 before backing off. So I think that problem may be solved.
Next issue I'm having is an annoying clunking whenever I hit bumps in the road. It's the exact same clunking I was getting with the old ttb front suspension. So I figured it must be the old worn out body mounts. I installed new urithane mounts and still have the exact same noise. Ugh. It sounds solid and on the drivers side floor I think. Any ideas?

my core support is going to need replacing soon. The radiator is still mounted solid but the support doesn't look pretty. The frame isn't torn and the steering box is definitely tight. All of the shocks are only about 6 months old. They were my 1st thought about that noise so I replaced them. As for the egt. Yes I am concerned about high egts. This is a somewhat daily driver that gets used to pull its maximum legal weight limit. I don't have the money for a new engine or new truck. It needs to last. Heat is the biggest killer of the 7.3. I was told to keep the egt 1300 or below for extended periods of time. 1400 max for short times (20 sec or less) if I want the engine to last. Since I can't find any evidence that those numbers should be higher I will keep them down as much as I can. The only evidence I've found of higher egts being acceptable are in engines built for competition that have upgraded pistons.

Your sense of egt is plenty safe, there's no problem with being careful but you have absolutely no reason to worry at those levels.
I can't remember if a 7.3 van turbo is the same or close to the 1st Gen pickups, but it's a solid up
grade for the gen2 pickups. It's be worth looking into because they are dirt cheap and even show up in junkyards.
If you ever have the heads off, clean up the valve bowls and guides....works magic for egt reduction.

I figured out the annoying clunking in the suspension. It turns out the upper bolt on the drivers side shock wasn't tight enough. It was tight around the mount but didn't clamp down on the coller inside the bushing.
Once the weather gets gets a bit warmer I plan on addressing the rust on the frame. Anyone have recommendations? POR15, Extend, Rust Sgt, etc. which is the best?
