Gone but not forgotten
I wasn't aware of the Mazda Protegé when this story was released in late 2002, but I just saw it on Car & Driver Television. Interesting story... Interesting car. :cool
MAZDASPEED PROTEGÉ
Remember the MP3? Here's the sequel. Better buckle up.

Callaway Cars, making its debut deal with an Asian manufacturer, was tapped to add turbocharging to the Protegé's powertrain.
Callaway adapted a Garrett T25 ball-bearing turbo with an integral waste gate for the project, developing a unique turbine housing for this application. To keep costs down, Callaway sorted through the Mazda parts bin and borrowed an air-to-air intercooler employed in a European turbo-diesel Protegé, as well as a higher-capacity radiator. A revised Visteon engine-management program increases fuel flow. By limiting boost to a maximum of 6.9 psi, Callaway and Mazda were able to avoid making changes to the engine's internals, although a new catalytic converter was required.
The net gain of all the foregoing: 170 horsepower (versus 140 for the MP3, 130 for the base version of the 2.0-liter DOHC 16-valve four) and 155 pound-feet of torque (versus the MP3's 142, 135 base).
