302 and a turbo
So, I'm planning on finding a turbocharger off of an old powerstroke deisel and fitting it to the 302 V8 in my '78 F100. The engine is otherwise stock, with the Motorcraft 2150 and everything. What kind of boost do those turbos put out, and would I have to make any other modifications?
Thanks!
Thanks!

To make any compressor more effective, you want to install an aftercooler.
Don't know about the capacity of the turbocharger for a PSD, but my feeling is that it's way too big for a 302. Most turbochargers have an operating range where they're most effective, and you generally want the smallest one that will meet your requirements so it spins up as fast as possible.

Is the engine in the truck using a carb or does it have fuel injection?
If a carb you will have many things you will have to do to get it to work. It's been done in the past before FI was common but today it's so much easier to turbo a FI engine that it makes no sense to use a carb.

With a stock engine, how much boost are you planning to run? 4psi? 6 psi?
Whats the power goal?
Chances are, the air won't be too hot at those lower pressures, and intercooler might not be needed.
You might want to check out "megasquirt" EFI systems, they have standalone EFI computers that you can use to do all kinds of stuff with.
And when I say all kinds of stuff, guys have made EFI lawn mower engines with it.
I don't know all that much about what you are doing, but if you think this will be a couple hundred dollar project, I don't think so.

I was in a mustang with a 302 and 7 psi, and it was pretty wild.
They got a 4.8 GM engine putting out 1200 hp on the dyno with stock internals, cheap ebay turbochargers, and custom tune. Actually I think they used studs and flipped the stock piston rings, but still, almost stock.
Do you know how much boost a 302 will hold without serious mods?
Is this going to be for strictly racing, or daily driving?

Well if it's a daily driver that you depend on for work, I personally wouldn't run that high of boost.
This is just going on things I've heard from people, run across on forums, etc, but I think 10 PSI would be pushing it a little hard if you rely on it.
Keep in mind you're also going to need high octane fuel, so no more cheap regular gasoline.
Unless you run a meth/water injection kit, but that costs money too.
Have you considered building an engine in your garage or something, then swapping engines?
It would be nice to have a fresh engine to start with, plus you can do a few upgrades before it even goes in. Engines of that era are not pricey, running 302's and similar are easy to find running for 200-500$.

I think a stock 302 block can sustain about 400 to 450 hp for short periods of time. Those power levels will distort the core, which will lead to parts seizing or breaking.
So if you're expecting the engine to put out 400 hp NA, it's not going to take much boost to blow it up.
Now, if you start with the Boss 302 block from Ford racing:
BOSS 302 CYLINDER BLOCK | Part Details for M-6010-BOSS302* | Ford Racing Performance Parts
It's good for over 1000HP, and you can probably get away with 15 psi of boost on top of 400HP NA. In theory, that can get you up to 800HP.

Or a 351, I've heard the 351 talked up quite a bit.
Certain years are very strong, and 302 stuff fits it.
Stronger than 302's anyways, according to a couple stories.
460 would be a cool option too.
If you are thinking of building in and then swapping, by all means, choose the engine that will cost the least to get the power you want.
