7.3 liter swap?
How difficult would it be to swap out my current 1999 6.8 liter gas hog for a 7.3 liter? I'm specifically wanting a 7.3, not a 6.0 or 6.4. The truck is a 1999 F250. Has anyone else made this swap yet? Any suggestions?
thanks.
thanks.

Damn, that's kinda tough decision, you could sell the V-10 to recover some of the costs of a new install, but I "think" in the end a 5.9 would be cheaper to install, plus you could get more power outta one. But I do applaud you for wantin' to keep it in the family LOL.

$10,000.00 and you've got yourself a 275 hp 7.3 PSD, maybe less, probably more, depends on how much work you do yourself...
You spend $10,000 on a Cummins (especially an older 12v) and you can have triple the power, but again, depends on how much you do yourself.
In a nutshell, you'll never find something more reliable than a 7.3 PSD, but never make anything close to the power of a 5.9 CTD.
I put about 25-30k into a 7.3 to come up with around 600 hp, I've got half that in the Cummins and I'm close to 1000. Of course, I have countless hours vested there.
What's your goal... reliability and fuel economy, or do you want the guy in a Corvette to look like an idiot.
I prefer the latter.

Jet, are you doing this with a 24V or a CR?
Kris, I know that 1000 HP is not all that difficult with a CR engine, and I'm pretty sure the combo is not some magical secret like bigger power is here in PSD world. I can tell you right now how to make 800 on fuel and 1000 with a shot of nitrous. With what I've got going in, I should be at over 600 on fuel and less than $5K in mods.
To the OP, auto or manual? Either way, you'll need the 7.3 ECM and wiring harness. The electronics of it will be the most complicated part and the 7.3 has quite a bit of it. The hard parts should be pretty much the same. However, I don't know of anyone who has actually done that swap.

the gyst of it:
Stock CR bottom end (with some treatment)
Bullet Cams steel cam
P7100 injection pump
A little Holset, a big Holset
It'll have one lone Industrial Injection turbo and the blue bottle when it goes in the truck.

You and me both buddy. I just fixed my puter again, among other things. Yeah, they are holding up to the tune of about 400HP. I suppose that is enough for now, yeah right. This engine will go no further as far as HP is concerned. Heck, I can hardly see out of the windshield for the dust and pollen on it.
