F250 SAS----Ultimate tow rig

[metalmacguyver]

I recently picked up a 1993 F250 diesel to use as a tow rig and a daily driver until i can get my ranger back on the road. Inevitably I find myself wanting to build it up a little bit better. I just didnt think it would happen this quickly.

Specs.

7.3L N/A IDI diesel
ZF 5spd
BW1356 manual tcase
3.55 gears
D50 TTB front
10.25 rear
Electric brake controller


Here are the plans for the truck.

1) High pinion kingpin D60 swap. The axle is out of a 1990 F350. It needs to be refreshed but is in otherwise good condition.

2) Hydroboost conversion. Change from vacuum assisted brakes to hydraulicly assisted brakes. This conversion effectively doubles the stopping power, increasing average line pressure from around 1100 psi to around 2200 psi.

3) Fix the rot above the rear wheel wells.

Here is how she looks now.

Here is the axle that will be getting swapped in. It has matching gears and needs only brakes. The brake parts on the D50 TTB will bolt right on so I will use those parts. It will get new ujoints bearings seals and kingpings if needed. It will also be sand blasted and painted before being put under the truck.

Here is the hydroboost unit that I pulled from a 1992 F450.

shorten the bed and swap on a super cab or even a crew cab if you don't need a long box.

Ahh see that's why I only have BII's at the moment, plenty of room for my crap!

Is that D60 straight axle essentially a bolt on swap?

And sandblasting is my favorite past time

i dont think you can. IMO the frame steps up to the bed right after the cab. the super and crews dont do that in the cab

Pretty sweet truck. Cool how you already have the plans in place for making changes. Question though: if the Ranger isn't street driveable and the F-250 is under the wrench as well, what are you going drive?

Actually it doesnt smoke at all. I suspect that the injector pump is probably pretty worn and as such is not actually moving as much fuel as it should be. If this truck serves me well, I will reward it with a new injector pump and injectors after the ranger is back up and running.

A turbo would be very nice but as of now, I am not going to start collecting parts for it. It has almost 400K on it and I need to make sure that the motor is not on its last legs before I go and start boosting it.

Yes, The D60 is a complete bolt in swap. Thats the only good thing about the leaf sprung D50 TTB.

Well, what I have planned right now can be done in a weekend easily so I wont have to worry about down time.

i see i see. yeah that could be it cause i have seen those things blow some smoke just stock. wait till you get a load on it. When i say blowin smoke though im not meaning blackin out roads, just to where you see a good little trail of it in you passenger side mirror lol
I agree on the turbo. def do a good check out on the motor before slappin the turbo on. Dont et them miles scare ya too much as ive seen guys put huge turbos and other external mods on motors with 300,000 and last for a damn long time. that 7.3 is a super stout motor too

thats a straight bolt in swap. even the x-member is pre drilled for the trac bar mount.
I suggest you go over to ford-trucks.com and check out the IDI section. Lots of good info there. You may not need a new IP, there is a fuel delivery set screw on your IP you can increase or decrease fuel delivery by turning this screw.

Nice truck

 

[metalmacguyver]

Thanks. I am actually on www.oilburners.net

From what I have seen it seems to be the TRS equivalent of IDI trucks.

I will play with the fuel delivery screw at some point but I want to make sure that everything else is in order first. A one of my buddy's uncles is a desiel tech and he specialized in the pre-powerstroke diesels. I am trying to meet up with him so that he can give it a very thorough check-up.

I installed the hydroboost system last night.


The truck stops freaking great now! I can lock up the brakes with out effort and that was not possible no matter how strong you were before.

 

[88ranger2.95sp]

2200 psi! Wow. That should stop you and the ranger on a dime. Sweet build..

Get the axle under there .

Are you ever gonna actually wheel it like with the ranger or is it just the tow slut?

Nope. It aint getting wheeled. It has 400K on the ticker and I dont want to beat on it. It runs very well and I dont want to risk it.
