diesel in a lincoln

well, technically yes, the 7.3 "engine" is bulletproof. the turbocharger and every single item that has a wire running into or out of it(read: sensors, computers, injectors, switches/valves/motors) are anything but bulletproof, reliable or inexpensive. plus, you can't turn a 7.3 up very far RELIABLY; they tend to come apart(con rods/pistons, head gaskets, heads...)

just trust me on this one. I've spent a LOT of time in the diesel truck world talking to guys, driving their trucks and turning wrenches/troubleshooting. I always wanted to get a diesel truck and the comparable mid-late 90's fords were going for $4-6K cheaper than the dodges, which I thought was great until I learned WHY they're worth less(not worthless, not completely anyway). I learned from the ford guys what sensors and parts you need to just keep in your toolbox or on your truck for WHEN it goes out, and it's parts that start at $150 that you absolutely can't limp home without.

Right now I'm running 40psi boost on my stock cummins and have 10psi more to go before I have to upgrade the head gasket and replace the head bolts with studs, in which case it'd be good for ~65+psi boost. I have plenty of EGT left to add more fuel(bigger injectors) with my current turbo but my current torque converter can't hold much more than 700ft-lbs of torque, have to get a better converter which is about $1K; then it'll be able to withstand 1,200 ft-lbs.

a friend of mine just got rid of his '99 superduty after two years because it's been so expensive for him to keep running. It left us stranded in mexico once as well as a never ending trail of $100-$500 electrical engine control components going out. Nail in the coffin was the injectors started going out, those are $350 each, times 8...just for the injectors. plus a solid weekend replacing them. dealership cost is just under $4k parts/labor IF they find nothing else wrong.

so why would it be a good idea to put a powerstroke in?

actually injectors are more then that, iirc like 750 a piece and yeah they do have some issues with cam sensors and a few with the turbo sensor and mabe just a few with the IDM.

What makes those parts so damned expensive?

Direct injection injectors ---- 25,000psi +

for one it's because they're electric controlled injectors and two they're kinda complex as far as injector design goes.
I'm sure there are dealerships that'll sell them all day long for $750, it was somewhere around 350-400 that he was quoted by this dealership, but the parts guy is a friend of his, so....

but to change them you have to go under the valve covers(which are burried) and remove the wiring harness that's UNDERNEATH the valve covers(yes, inside). It seems to be a nightmare.

I just don't see the point of swapping a powerstroke INTO anything as most guys wish they didn't have it but they love the rest of the truck so much they just deal with it. I can get the same power with more reliability from a 3.9L 4 cylinder cummins as I can from a 7.3L V8 powerstroke, while getting better mileage. that sounds rediculous, and it is, for navishard.
