Lot's of ideas. First off, tell us what you have so far, how quick you want to get there, and how much money you have to spend?

Welcome to FTE.

Who built the tranny? Do you have PMR's? Did you just cut the muffler out or did you go with a new turbo back exhaust? How big of a lift do you have and what gears in the rear end?

If you have PMR's, it's generally advised to stay on the South end of 400 hp or you risk windowing your block. There are some running North of 400 on PMR's, but they tend to get nervous.

Exhaust sounds fine, what about air intake? The crappy stock box will dust your engine if you start adding power.

Now don't take this the wrong way, but we really should have a conversation about your transmission too. Did he give you anything in writing saying he backs the tranny up to 650? What about torque numbers? If he's used to gasser trannys, a diesel puts out a lot more torque at much lower rpm's.

The trans computer comment is also of a concern. You can adjust line pressure with a chip, or you can adjust it within the valve bodies, but the 4R100 doesn't need some separate trans computer to go along with it.

I'd politely ask if there were any shift kits like transgo or sonnax installed in the valve bodies. I'd also ask what specifically was done to make the tranny better. Just tell him you're trying to learn about this stuff.

I don't know where all the big HP guys are. I figured by now the others would be chiming in. Are you looking to make those numbers on straight fuel, or are you considering drugs? (meth injection)

You can barely get a turbo & injectors for $5k. You'll need a lot more than that for 550-600 hp......

Aren't you nervous?

I'm not nervous...











550ish can be had with 238's (100% or 200% nozzle) and a modded H2E, with GOOD tuning.

Stock 17* in good shape will support 238's, the stock fuel system will support them as well. You'd be better off with more oil though, and more likely to hit your goal.

But, 550 is gettin close to the head lifting range, so add head studs. Valve springs are a really good idea over 40ish pounds of boost. Depends more on the turbo IMO though, and how much backpressure you're workin with, since backpressure is almost always higher than boost. And don't replace valve springs without replacing pushrods, or you'll just be goin back in there after a while.

Don't forget a boostfooler, and the stock IC pipe boots probably won't like the boost you're pushing.

550 for 5 grand is almost impossible. Unless you're sponsored or something.

Plan on 7-10 grand, and that's all motor parts. If you go tearin around on 550 without trac-bars, plan on replacing a rear end. So go ahead and add some more money for those.

Then add some more for whatever I've forgotten to mention.

550 that runs right, total package not skipping things on the rest of the truck, is probably gonna be around 12k.

Welcome. I don't know how old you are or what your knowledge and background is with these trucks but I'll politely say first that your posts are hard to read and understand. Just try to make sentences that can be comprehended and not run on and on and be specific with what's been done to your truck and the transmission. Then people here can help you a little better I'd bet.

But with a $5000 budget methinks you should take a breath and slow down a little and read up around here. You might have your sights set a little high thinking you can get 550hp. It takes a lot of money to make a 7.3 live at that level. 5 grand ain't gonna do it. You'll need $2000 easy off the bat just for a turbo to support that power. There's a lot more to it than just slapping some big injectors in and getting a chip like is posted above. I'm not a big power guy so I can't help with specifics but I know what it would take and it's too rich for my blood.

Tuning is key.

There have been quite a few trucks out there on stock forged bottoms makin impressive power in the last year or so, with the latest lessons learned.

What you're starting out with makes the biggest difference in price.

01-03 (PMR) 7.3? 15-20k to get close to 600.

OBS-00 (Forged) 7.3? South of 15k, probably closer to 10-12k.
