If you just do it over a time period, I would do it in this order.
1. Buy a truck, try to get the lowest mileage you can, but don't be overly concerned with that. 1999 and 2000 will have forged rods.
2. Hutch and Harpoon the very first day you have it.
3. Intake, a 6637 and a short piece of 4" pipe is cheap.
4. 4" exhaust turbo back. Many good choices out there, with or without a muffler.
5. A chip, lots of options there, pick a tuner of your choice, mine is Tony Wildman.
6. Head studs, it is insurance for a later date.
7. A HPOP lots of good medium oil choices, all of them except 1 is a good choice, my choice is Adrenaline.
8. A transmission, the 4R100 does not like added power, once again insurance for a later date.
9. Build or buy a fuel system from the tank forward, works good now, and insurance for a later date.
10. Injectors and a turbo, not many choices for a drop in turbo, but if you spend the money for a T4 mount, you have hundreds of choices. Injectors, lots of good builders, make a choice. You have to have your chip reburned to match these combos. Tony Wildman has free reburns. And he is a really cool dude.
This can all be done in one wallet crunching weekend and you have one big grin for a while.
Or you can spread it out over a couple years and have a big grin with each and every upgrade.
You notice I throw a lot of supporting mods in before adding the power, much easier on the wallet that way.
