I am planning on puuting the 4" exhaust, bigg boost, wiked wheel on turbo, banks waste gate, SCT tuner, and i already have the huge donaldson filter. After that i should be putting out about 580 ft lbs of tourque, will that be too much on the drive train or will i have to upgrade transmissions ? Its a 2002 7.3 with 183,000 miles on it f250

 

That is quite a bit of work for very little reward. Take a look at this thread

See post #8 which represents what is considered a mildly modified engine. That is about the max you can expect out of stock injectors...

The 4R100 is rated for 1000 ft/lbs of torque so ANY increase in engine output is going to exceed that number due to torque converter multiplication factor.
