Performance out of a 7.3

I'm sure this has already been posted, but can someone give me an idea of what it takes to bring a stock 2002 7.3 up to decent performance level as far as HP and torque? I know stock these trucks are around 200HP. Is that their limit? What options are out there?

What do you call decent hp? 350-400-450-500?

350-400 would be suffice. I'm not familiar with what people are able to get out of a 7.3 with reasonable add ons. That why I'm asking.

Money break out the wallet. If you want good reliable power be prepared to drop the cash.

2001 F350 Lariat 6 speed, South Bend clutch. 4inch turbo back, Tymar intake. Garrett GT38R. Swamps 175/146 injectors. Driven regulated fuel return. TS 6 Position Swamps Tune.

Really, so i buy a 7.3 in good sound condition and want to up the HP, I'm gonna have to drop a lot of cash to make it happen? How about a 75 or 100 hp tune?

350 can be achieved fairly easy. chip tuned by tw, php, dp tuner etc.
standard air intake, 6637 DIY, afe, s & b whatever flavor you like.
any 4" inch exhaust system.
that will get you about 320-330 hp
then you could get a modded idm by swamps should put you around 350.
400 hp same mods just upgrade the injectors to stage 1 single shots like a 160cc injector. might look into a valve body for the tranny to keep it together.
you ll probably either need a 38r turbo for stage 1 injectors or i just saw that a new wicked wheel just came out for the stock turbo that made 43 psi with single shots!
and possibly look into get a frx from riffraff or a full regulated return thats up to you.

99.5 f250 7.3 4x4 257k
PHP Phoenix, S&B CAI, 4" TBE, Hpx, Stancor, RR Billet Wheel, AIH Delete, Autometer Gauges, Leveling kit, Transgo kit, Warn Hubs, Int'l Up-Pipes, RR IC Boots, Non-Ebpv Pedestal, High Flow Outlet, RR OCR, 08 Tow Mirrors.

I'm not looking for the same performance as my 6.7, just want to give it a little more azz than stock.

chip, intake ,and exhaust wakes them up pretty good from stock. after that the dollar to hp ratio really is not there to me.

Thanks for the info guys. If i end up buying it, I'm sure i will have more questions. Thankfully my brother in law works on the 7.3, but doesn't do a lot of the performance stuff that ya'll do.
