Making an 02' 7.3 "fast" - can it be done?

Obviously it can be done if money wasn't an obstacle... but I also own a 6.woe that I'm nearly done with installing new head gaskets and studs in. After it's complete, I was thinking about doing a few performance tweaks to the backup rig, my 02' F250 7.3 reg cab 2wd.

If I went the typical route - intake, turbo back exhaust, and a 6 position chip from PHP, how 'fast' would the truck be, say, in 1/4 mile times? 16 seconds? 15, 14's? Doing the same work to the 6.0 was worth it IMO, it made the truck far more enjoyable for my taste. I'm wondering if the 7.3 would respond similarly to modification, or am I better off spending the money elsewhere.. perhaps on just appearance mods.

Load the stock oem tune onto your 6.0 and take it for a drive. A stock 6.0 with intake and exhaust will be fairly comparable to a 7.3 with intake/exhaust/tune.

Its a reliable motor but not much of a powerhouse. My father in law owns a tuned 7.3 F250. I think I can run faster. And when he turns it down for towing, I think I can walk faster. lol Its fun for him since this is his only diesel and his other ride is a hybrid escape. But if you're used to a tuned 6.0L it won't be so much fun.

I've got a 2wd single cab 7.3 with a few mods, and it moves pretty good. Big mods are a GT38R turbo and stage 1 single shot injectors. Not sure if you want to go that far with it though. Being 2wd single cab its a lot lighter, so thats a big plus. I would say my truck is in the solid 13 second zone.

Full mods if interested are:

GT38R
Rosewood stage 1 single shots
Stealth HPOP
Regulated return / bowl delete
Snow performance water / methanol injection
4" straight pipe exhaust
DP Tuner - live tuned by Jody of DP tuner

I have a WW2 and different intake to go on soon to get a couple more PSI out of it. That will be about it for the injectors and stock bottom end. Its really fun to rip around town with, and is pretty quick for a pick-up.

That's what I would do. Reg cabs are perfect for that kinda of stuff. I actually thought about looking for one to build into a race truck, but that is waaaaay too much money for me.

Yep... Those are some high dollar mods. The turbo alone costs more than i paid for the truck!

Actually I would say:

Brute 66 turbo from NLTD
Hybrids... 200's or 238's... P.I.S, swamps, Rosewood, etc
6637 intake
Exhaust
Tunes-- TW, Gearhead, PHP and either a TS, or Hydra chip. Or if you want live tunes, done by whoever is closest to you but still on a TS or Hydra

HPOP--- if yours is healthy there are many people running hybrid injectors just fine, yeah youll get more with an aftermarket HPOP but it's not something needed right away.

Fuel system could be left alone too, I certainly wouldn't spend the money on a bowl delete not unless I was going much farther than the mods I listed. an Frx and regulator housing with the bigger springs and youll be done.

A secondary fuel pump is optional, I've driven a truck with one, it definitely helps.

Hell mine ran a 15.9 with a crappy Hypertech programmer and intake and exhaust. Probably would be about the same now with these sh!tty canned tunes from TS.
