Good down pipe!
Yes the 6.0 cooler will work great. That is what I used.
You need gauges my friend.
It looks like you are full tilt PMS (powerstroke mod syndrome) You have come to the right place.

Take a look at my sig in H2e install pics. I have some pics of the 6.0 cooler install. You will see my 6637 in the final pics.

Looks like after the cooler you might be plenty ready for some new injectors then a good chip from TW or DP at the same time.


... now lets talk turbo's!





Oops did I get ahead of myself there? Sorry
Sounds like you went to the right place for the tranny work. He is the best IMO. Just be sure to keep his # for when you need more than just the VB from him.


Welcome to FTE!

 

well congrats on joining us here at FTE and deffinetly the place to go for anything you need.

if you want a better 0-30 time you can get a custom chip, which is the way to go for our trucks, stay away from banks and other crappy ts chips which are just canned tunes that dont get pottential out of our trucks, some one like Power hungrey performance or Tony wildman or Dptuner which they all extrapolate TONS of power from out trucks with custom tunes up to 140HP and 100 at the wheel. just by removing the cat you get a whole lot of tunes from a happy singing turbo, but a 3" downpipe is a great choice, not a whole lot of sledging to make it fit and going to a 4" after the Downpipe is huge gains and economy. if you want to do injectors which sounds like you already have the built tranny fofr then your good to go, stage 2'sare highly recomended, rosewood injectors from jim are exelent and makes your truck a a whole new beast. but your IC is just to keep your EGT's which are the silent killer, but it all depends on your setup and how muchyour on the GO pedal; but deffinetly get the napa 6637 filter and 4" pvc or bent tubing and gut the stock box, just leave the air flow sensor dangle or zip tie it to the filter. jsut the filter alone lets you hear the turbo sing.

 

Dale sends directions with the downpipe on how to install. You have to cut the seam where the floor pan meets the firewall a few places and take a bar and flatten it and it fits in. Install top piece from top and bottom from underneath. I did my whole exhaust myself including removing the old one in a saturday morning.

 

I would recomend to you Rootar, first try to flatten the seam before cuting it, with a porta-power, as I did and worked very well, and you will not have any troubles with the oxidation in the cuts of the seam, as somebody has reported or mentioned. But also I have read that the space there is a little different between each truck and depends how the motor was seated in the supports in the frame (a little back or FW). So first take a look how is the space there, and make your decision, OK.

And for sure WELCOME to

 

ill prolly hold off on the injectors and turbo as that would cut into my other funds at the moment unless i can talk the old man into helping me out, but we just got in a S & B intake in this morning for our 99 7.3L and it looks top notch shields the filter from the engine heat and takes air from right behind the grille/head light and look trick witht he clear lid. SO im thinking ill go with an S & B intake, get our 6.0 IC on there, and a new down pipe and full 4inch system, i think that would give me some noticable gains right?

 

I like the looks of that S&B unit. Pretty sure thats the one I'll go with. Gotta do the lift pump soon so I'll throw the new turbo on it at the same time. I'm still undecided about exhaust so thats gonna have to come later. Should see a marked improvement with your planned mods.
