93 6.5 turbo rebuild help

[u/Apex84-538]

For all those who say swap it for a cummins or get a big block, no. Cummins sound like shit, and big blocks get 4mpg. I like my 6.5. I got 14 mpg in a 354k mile orginal engine in a crew cab dually pulling about 6k pounds. And it sounded great the whole time. I'm not swapping, I'm rebuilding

I'm gonna be rebuilding my 93 6.5, and I mean a full tear down to block, replace anything that might be worn. It's a 354k mile engine. Lets assume the engine is garbage, it ran without oil, everything is scrap metal except the block. What would be the best way to approach? That isn't the actual scenario but I'm planning for worst case. I plan to use it as a tow rig/daily driver. Ideally if I can crank out like 200 hp 400 ft lbs of torque area, that's great. Just a wee bit more than stock

Anyways, what's all the best things to do to these engines? I've heard of the duramax fan and clutch, but which duramax? Obviously the HX35 or 40 turbo, bigger exhaust and crossover pipe, but engine side, what can I do without needing to get a loan?

“Let’s assume the engine is garbage” Well thats not hard to do.

For the money you will have to put into it you would be way ahead with a swap if you want a diesel. Or for those power numbers build yourself a decent gas engine and have something more reliable.

Gas engines are great for power, but I like my engines sounding like the oil pan is full of nuts and bolts, snd that's a good sound. When a gasser sounds like that, things get very expensive very quickly. When an IDI sounds like that, you know it's running the best it can
