Hi Everybody,
This is my first build thread. I started out just looking for an 85-87 turbo diesel ranger. After 3 months of searching, one showed up on Craiglist. Unfortunately the truck was in terrible shape. Luckily it was a good price so I picked it up anyways. I pulled the motor and transmission out, a 2.3 Mitsubishi turbo diesel 4D55, and a Mitsubishi FM146 transmission with electronic Borg Warner Transfer case. I scrapped the rest of the truck aside from a a few other parts. I pulled the head of the motor and to my horror the cylinder walls and pistons and valves were in bad shape. There was long deep scratches in the walls, and big pits in the pistons, the head had a few dings in it as well. The motor ran when I got the truck, but it smoked white like no tomorrow. I attributed this to bad injectors or a problem with the injector pump. Looking back on it now, it seems like the poor condition of the bottom end was the culprit. Anyways, I decided the rebuild the motor. I sourced alot of japanese manufacture parts from online, new pistons, cylinder liners, rings, all the seals, waterpump, new connecting rod bearings and pins, and gaskets.
I was able to do most of the machining at my work (I am a machinist). I decked the head, and cylinder block. I installed new liners and had a local engine shop hone them to spec for me. I also rebuilt the cylinder head, new cam shaft, new upgraded roller rocker arms (from a 4D56). The valves seats were honed to match my newly ground valves. The old turbo was also shot, and I had a machinist friend who previously worked at a turbo manufacturing shop source me a new one with high quality Japanese journal bearings and coolant lines running to the cartridge (the one used in a 4D56). The motor is basically complete now, just need rear main seal housing and oil pan installed. Its also rocking a nice new paint job.
The truck this is going into is a 1991 regular cab 2.9l V6 4x4. It was a rebuilt truck with a nearly perfect body. I removed the bed and de-rusted the frame and painted it with chassis saver. The breaks have all been replaced, and new soft lines installed as well as a rear hardline. The interior has been ripped out and the slightly rust floor has been ground clean and is waiting some Tremclad paint. Over the next few months I will be swapping out the motors and getting this thing running. Here a bunch of pictures of my progress so far.
I will include more photos.
Regards,
Mike
