power potential 03?

[jayjma20]

just wondering what the potential to make good power is with an 03 7.3l, i know its ratings are lower than the 6.0l but its a much bigger motor, any input would be great

About the same as anyother 7.3... 650-750... With a fully built top end, bottom end, injectors, turbo (or turbos), Nitrous, Water-meth... and a tranny....


With just a chip, intake, exhaust... your about 300hp...

Your 03 has PMR's (Powdered Metal Rods) so without tearing into the bottom end you are limited to about 390-420... The Forged Rods seem to be safe to about 500-550...

thanks for the input, what year is better? also what mods would you suggest for towing

[CSIPSD]

If you not looking at really moddin the truck the 03 is the nicest year of the 7.3...

Chip, intake and exhaust, a good set of gauges. That will make a nice tow rig. Save a bit for a Valve body for the tranny and an ATS compressor housing for the turbo.

thanks again, whats the purpose of upgrading the turbo, is the stocker just a poor set up? what about inter cooler upgrades?

Stocker is known to surge... which will destroy it in short order.

The ATS housing will eliminate it.

You could add a Sperco IC to that mix, but at stockish power levels its not nessasary.
