Power difference between 4.6l and 5.4l
I have a smallish turbo that a friend of mine gave me and as things go I want to use it, so I have been looking into things to get it going. I know all about the different parts I will need and what I will need to get it going my question is with two identical engines will there be significant gains with one over the other if they are both turboed with a smallish turbo.
I say small because my friend that gave it to me was originally going to put it on a 6 cylinder car but then sold said vehicle.
So the comparisons would be:
1997 4.6l Non-PI vs 1997 5.4l Non-PI
2000 4.6l PI vs 2000 5.4l PI
would the power gain be worth getting a newer engine(junkyard) and rebuilding/building it up or just rebuilding the '97 4.6l engine I already have and getting PI heads in the process. Also how would the PI heads effect the compression of the engine.
I guess I should say I am usually towing/hauling with my truck and ocassionaly driving at my deer lease and on the beach but racing and mudding are not things I do with this truck.

starting a turbo project on a 20 year old daily driver because you got a free turbo....not a good idea.
whats your budget? Do you have the extra change for a new motor and transmission if (when) they blow?
if you have a 200 hp motor and with a modest turbo you make 300, after several thousand in modes, why not just sale the truck and purchase a 2005 up 5.4 with 300 stock?

Well I'm either gonna rebuild the current engine or buy and rebuild a 5.4l with new parts so no not turboing a twenty year old engine, as for the transmission I'm looking for a zf5 or zf6 out of a 1999 or 2000 f250 so it will be much stronger than my current m5od
Also this truck isn't a daily driver so if when the motor blows I'm not stuck without a vehicle and since I'm not in any sort of rush this project isn't going to happen till after rebuild a motor which is why I'm trying to find out if I will be losing out on a lot just rebuilding a 4.6l non pi engine vs getting a 5.4l pi engine and rebuilding that

To me there would be more aftermarket parts available for a Lighting type transplant.

$6k is a bit high but it's just an example.

I did a 3 inch body lift a few years ago since I had wanted to do the transmission swap then but didn't have the money now ask me if I will ever do a body lift on my own again and I will emphatically say no I also understand why the body lift cost just over a hundred bucks and the labor is about 5 or 6 times that

The main reason for suggesting the roots/Lysholm type of FI is that has been the standard performance upgrade for the 5.4 series of engines. When you go with a turbo there is going to be a lot of custom tuning and fabrication required to make it reliable. That said, a Turbo install would be fun.
