Installing a larger turbocharger and intercooler system is one of the best upgrades you can perform on a ’94½ to ’97 7.3L Power Stroke. And (as promised) that’s the direction we’re taking this month in our pursuit of 500 rwhp. We’re adding a new T4 turbo mounting system, an S300-based turbo, and a Spearco intercooler.

Groundbreaking Turbo Mount System
Even though the early 7.3L Power Stroke used the common T4 turbine inlet flange, the factory exhaust collector and short-length up-pipes mounted the Garrett TP38 turbocharger (which came with no map width enhancement groove) virtually on top of the driver-side valve cover. This tight packaging made it virtually impossible to mount a larger turbo using the stock pedestal, up-pipes, and collector. The 7.3L gurus at Irate Diesel Performance, who were already building complete T4 turbo mounting kits for ’99½ to ’03 Super Dutys, designed the breakthrough turbo mounting system we’re installing this month. Essentially, Irate’s T4 mount allows you to run any standard T4-equipped turbocharger on your ’94½ to ’03 7.3L (be it a BorgWarner, Garrett, or even Holset).

In order to shoehorn the massive Spearco intercooler into place and install the new turbo system, we took our ’97 F-350 to Randall’s Performance in Gladstone, Illinois. Thanks to its expertise, our fabrication needs were a non-issue, and very few headaches surfaced when bolting on all the following upgrades. Make sure and tune in next month to see if we hit the 500hp mark on the dyno.
