My m925a1 build "Brutus"

Forgot to mention, many of these come with a fuel bowl with a water sensor,, so you can head off a problem with bad fuel before it can get bad...

Truck did fantastic going to Redball Military Show this year. Truck drove 320 miles round trip give or take and did flawless. Truck was a dream to drive. At 50 mph I'm at 1450 rpms. I get more noise from the tires then I do from the engine. Feels like it's idling. Truck towed the m105a2 with no issues. Heater core I replaced works like a charm. Very pleased with the trucks performance. All the parts are being purchased for the turbo build. Essentially waiting on the downpipe and I can start the turbo build this weekend.


Here's some photos from the show.

After getting back home I drove the truck and noticed fuel leaks coming from the pump. I decided to "bite the bullet" and had a pump rebuilt by premco. Put the same 27 fuel button but all new gaskets and internals to get rid of old leaking seals and make sure the internals of the pump are good for the next 40 years.

Truck is significantly more responsive to throttle and feels like I gained some power. Very pleased with the pump. Warren and the guys at Premco are top notch. Highly recommend them. If you are on the fence about it, just do it. You won't regret it.

One of my best friends turboed his m925 and has had nothing but positives about it. I decided to follow suit. Overall I am looking for lower temps on mountains and hills and a little bit of power gain. I decided to get a brand new pulse manifold. I went with a Borg Warner BHT3B. More photos to come. It has a 26cm rear housing.

I am also going with larger injectors from Premco. Plan is to order some 20% overs. This will flow more fuel and drop the fuel pressure so if I go up in a smaller button down the road my fuel pressure will still be safe. I also want to check the screens on the injectors anyway so while I'm in there I might as well make some improvements while I'm there.

I am also running a big cam aftercooler. Plan is to run it without the heat exchanger inside for now.

Had the parts powdercoated at my local shop. Check out Gillotts Blasting and Powder Co. They can do any color you want. Super nice guy. Great quality and pricing. Here's some before and after photos of the parts. I also decided to powdercoat some tow bar brackets. (More photos coming up)

Bought a catch can for the truck as well. Wanted it vented and didn't want dirt and grime getting sucked back into the engine. Got a universal kit with 5/8" inlet and outlet. More photos on that soon.

Once the turbo and aftercooler are installed I can work on the piping for rest of intake and exhaust.

Just curious, who is Ken Spencer??

Got the Down pipe for the turbo build. It's off a freight liner. Ordering my new injectors tomorrow. Plan on starting the turbo build end of this week. Lots of photos and videos to come showing the difference in power, temps, etc

I painted up the towbar. I have some tow bar clamps I powder coated black and is mounted to the front bumper. I'll have some photos tomorrow of it mounted up.

These are the tow bar clamps and the tow bar in place. Looks mean. Might have it powdercoated in the near future black for a nice contrast.

Removed the stack and pipe under the cab in preparation for the turbo. Also received my injectors from premco. 10% overs. Based on my pump settings, Warren from Premco said this would be a nice upgrade and still give me reliability and not stress the engine. Not looking for a big powerhouse but some whistles, lower temps and some power wouldn't be a bad thing.

Sgt Tibbs wants to know what I got him.

Removed the S pipe exhaust and the intake manifold to make room for the big cam aftercooler. I need to figure out how to get that S shaped fuel line away from the block. I don't know if the aftercooler will fit there without rubbing. Will need to dig deeper when I get closer to assembly.

Next is to drain the coolant and remove the surge tank. Surge tank is getting moved behind the cab, possibly moved to the spare tire mount. Haven't figured out exactly where yet. It will be one of the last parts of the build so I'll have time to think It over.

If you haven't done it yet, it may be time to do the dual fuel mod with new fuel line routing.
