Putting a '75 body on a '00 frame w/7.3

I just posted a question about how to get a neglected 7.3 ranch pickup back into running condition. I've come up with a spare 7.3 that needs injectors but is in otherwise good condition. I've decided to go ahead and upgrade everything while I'm at it so I can have one helluva truck when I'm done. :burnout
I want to bump the truck up to about about 700ft lbs at the wheels, or whatever the most power for reasonable money area is.



What upgrades should I make to the Fuel System? -- I'm already replacing injectors, can I get away with using low cost stock remans or do I need increase injector size to hit 700 rear wheel tq?
-- Due to the high milage (225k) I'm thinking the fuel pump should be repalced also, would a factory one do or should I upgrade?

What turbo (or parts for my turbo) should I get?
--I've heard of some guys talking about a new impeller thats supposed to work wonders, what is it called and how $ is it?
--I'm going to have a homemade cold air system/snorkle and a 4" exhaust built so that should help airflow

I would still like to keep within 15-18 mpg range at hwy speed
-- I don't want anything thats going to be too expensive to drive

And finally, the best part of all... this '00 frame and drivetrain is going to be stuffed under my old '75 F-250! Since the body is hashed I might as well have my old truck running again, and the modern components would make it into a great truck for less than it would cost me to fix it up as is (and still have drum brakes, no p/s, cruise, or a/c)

Any words of wisdom on bumping up the power on a '00 7.3 would be greatly appreciated!

I will keep pictures and progress posted for my "Franken Ford" project.

As far as the fuel system, Walbro makes an upgrade fuel pump, but I don't have a p/n for it. See if someone else can chime in & you always have other choices from FASS & AirDog, that tend to be a little more expensive. For your injectors, you could always upgrade to a single-shot stage I or II hybrid & get a bigger turbo like a Garrett GTP38R to top off the combo. The compressor wheel you're talking about is probably the Wicked Wheel. It's basically a '94-'97 compressor wheel that claims it eliminates surging, it won't do too much to help you get into the 700lb/ft. you're looking for. Look into getting yourself @ least a 3.5"-4" exhaust for the whole set-up & most importantly, get your hands on a trans. temp, boost, & pyrometer gauges. If you do any type of modifying, whether you're looking for torque or speed, gauges are the most important mod you can get. The AutoMeter Z-series are the cheapest you can get.
