It was Jack Roush’s lifelong passion for hot rods, racing, and Mustangs that was the driving force in the 1995 creation of Roush Performance Products , a company offering an extensive line of aftermarket performance parts, vehicles and crate engines. With the creation of Roush Performance, Jack Roush began working with dealers to customize a car that he had always had a passion with, the Ford Mustang. Jack Roush’s first attempt to deal directly with Ford was actually in 1988, when Roush introduced a 351 cubic inch, twin turbocharged Mustang, which was a hopeful 25th anniversary edition, but this 400 horsepower Mustang was turned down by Ford due to the costs of production.

1994-1998 Roush Mustangs
The first generation Mustangs from Roush came in 3 Stages. Stage 1 was an appearance package and consisted of the following:

Roush claimed a gain of 47 horsepower with only the included items of Stage 3, and while the GT-40 heads were not included, a reported gain of 120 horsepower was obtainable with the Roush machined GT-40 heads.The Stage 3 Roush Mustang added the following to the Stage 2:
