As the title says, I bought me a first gen Dodge Cummins.

 

It's a 1991.5 D250, regular cab, with a getrag 5 speed. The odometer stopped at 154,000, but the PO said it has about 160,000 on it.

 

Dad and I drove nearly 500 miles up to Arkansas to pick it up.

 

The rust is just surface, it's not bad yet.

It has some electrical problems. The most important one was to get the turn signals, head lights, tail lights, and brake lights to work. I feared the worst, and thought it might be a bad grimlin. After an hour or so of checking the obvious things out, I reattached a ground wire, and the headlights worked.

With dad's help, and a test light, the signals were getting power, and so were the park lights, but one would signal, but the park light wouldn't work, and the other light was just the opposite. Turns out 1 bulb's signal filament was out, while the park light filament was good, and the other was just the opposite.

One rear tail light worked great, and the other did nothing. After chasing some wires, we found that the wiring harness going to that light was pinched between the frame and the recently installed rear bumper, nearly cutting it in two. Re-wired that and it's good to go. Now I can pass the state inspection.

 

The other issue is the gauge lights don't work... Haven't looked at that yet.

Also the key ring light stays on, and eventually drains the battery. I just pull the #10 fuse and it fixes that. (for now)

 

It needs a little front end work, and new tires, and I need to fix the E brake, and install new door hinge bushings.

 

The interior is clean. The dash is not cracked, along with the windshield. The seat is not ripped, the headliner scores a 9.9 out of 10. It's missing the carpet, but I'm fine with that - I'll put down some good floor mats and call it a day.

 

For $2,400, I'm happy.

Got on the dyno today.

 

Made 282HP/692 ft/lbs torque. Still on stock injectors.

Run 1 (pink) was with the stock fuel pin. (O/D)

Run 3 (green) was stock pin, in 4th gear.

Run 4 (orange) was The Hungry Diesel pin. (O/D)

Run 5 (blue) was THD pin, and KSB on for more timing. (O/D) Did 282HP/692 ft/lbs.

I think it coulda done better with an 1/8" timing bump, IDK.

HX35 was gated to 35 PSI, and max RPM was 3,400. Hit 1,200* EGT for just a second.

Only fatality was the FSS. I also noticed some fuel in the AFC after those runs.

I've heard nothing but good about the dyno at Relentless Diesel, so I feel confident in the numbers.

Those are some nice numbers, especially for stock injectors! Looking forward to where this is going.

 Pretty cool. Got my stock 02 beat. Not sure what it is now. I also don't think my butt dyno has a print out. If it did it would say 800hp and 1500 #'s of torque at 1500 rpm.. All on RV 275's!!!!!

Well after pulling the Getrag twice last September when I rebuilt it, I told myself the next time I pulled it, an NV4500 was going in... Well, the Getrag needs pulled soon, so I ordered an NV4500 with a conversion kit, and it showed up today. Sometime in the next few weeks, that will go in.

 

Yesterday I installed my Hungry Diesel 6x.013" injectors, flowed to 81 LPM (stock is 40 LPM) and set at 260 BAR. These are waay too much for an HX35, but with a light foot, smoke is manageable and EGT's are not even close to being an issue. I have A LOT of tuning to do though. Timing is set at at roughly stock right now, and the starwheel is pretty close to the bottom, so I can easily clean it up for DDing. I'm babying it for a week, so see what kind of MPG I can get.

 

Haven't romped it yet... I'm skeered.   But I will say, getting on the interstate at 1/4 throttle feels the same as 1/2 throttle, before the injectors.

 

Haven't done anything since I put the injectors in, except change a wheel cylinder, and drive the dang thing.

 

This truck is a blast to drive now, even with it still being restricted by the HX35. Lots of power, yet easily daily-driveable with no smoke, and absolutely no EGT issues. It will black out the sun if I make it, but it's easily controllable with the right foot. And fuel mileage has not changed.

I'm saving up for a 62 SX-E. I thought I would buy one with my tax return, but thanks to (expletive) Obama, what tax return???

 

The NV4500 is going in this weekend. Hopefully all goes smooth with that, and I don't have to pull it out for a while.

 

Hoping to have a video or two soon.

Look forward to it.

I wish Dodge made suburbans throughout the 70s and 80s. I would own a 1st gen cummins powered 4door ramcharger.

Did you see the one the guy had custom built over on Cummins Forum?

(he may post it on other forums, I don't know)

 

If not, I'll post a link.

I'm slacking on the updates.

 

The NV4500 is in, and seems to be doing good.

2 weeks ago I bought a BW S362/68/.70 SX-E, and I installed that last night. Things are coming together performance wise. I still need to add timing, and do lots of pump tuning, but it runs strong.

 

Pics and videos to come soon.

Nice clean engine bay! Turbo specs?

Thanks, it's getting there. Still need to paint more parts, and clean up wiring.

 

62/68/.70 SX-E

I've had no time to work on this thing. Still lots of pump tuning and timing to adjust.

 

Here's a 45-85 MPH roll-on.

Oh lawwwwd that sound!!!

 

She looks pretty quick as is! What rpm does that 62/68 like to start spooling?

It should sound nastier with more timing. I love that deep growl.

 

As it sits, it starts building boost at 1,600 RPM, and by 1,700 it's ready to takeoff.

And even though it's making boost, it's 2,000 RPM before I'm cleaning up smoke, and even then it hazes under heavy throttle. That's mostly due to the power screw being in as far as it can safely go. (which controls duration, so yeah, it's going to be dirty with lots of duration in my setup)

 

Like I said, lots of pump tuning still to do. I'm happy with the power, I'm just trying to get it to run cleaner.

 

After it's all dialed in, I'll hit the dyno. Goal is 400/800, but would like to get closer to the 450 HP mark. (which is hard to do with a VE truck)

No major updates... Last weekend I took a 400 mile round trip to pick up an all-aluminum powerstroke intercooler. Drove 65-70 MPH, and got 20.8 MPG.

So far Ive given people rides, and raced one 2nd gen... Everybody is pretty impressed with the power in this old farm truck.

 

Lookin good! I've been debating doing the same with my stickers! 

Exhaust change up...

Update as of Sunday...

Seals failed on exhaust and intake sides. Pumped the charge pipes and intercooler full of oil, but luckily it didn't get past the intercooler.

Slapped the HX35 back on, and dang if those seals hadn't gone too. I guess from sitting dry for 4 months? 

Sent the S362 out to be warrantied, and ordered a rebuild kit for the HX35. Hoping to be back on the road by the weekend.

 

Debating on compounds, or run the 62 a while longer after it gets warrantied.
