It’s getting to the point where 2011-2012 Mustang GTs have become affordable to the common working stiff. However, like every Mustang, our concern always comes down to how many miles are on the car, and generally, the more miles, the cheaper the asking price.

Brenspeed recently decided to let us in on a little experiment by seeking out the highest-mileage Coyote it could find to see if using such a car was a viable building block to performance. What Brenspeed is starting with is a 2011 Mustang GT automatic with 163,000-miles on it. Brenspeed’s Brent White says, “The two-owner car was 100-percent stock and had a nice stack of service records.”

Once the engine is found in good health, or restored to full health if need be, Brenspeed will get busy installing components from Kooks, Ford Performance, Strange Engineering, Circle D, Mickey Thompson, BMR Suspension, Afco, JMS Products, and Race Star Industries. Tuning will be handled by Brenspeed.

With those service records in hand Brent thought the GT was an ideal Mustang to build. “The car, although pretty clean outside, had an engine compartment that looked every bit of 160,000 miles,” Brent says. The first thing the Brenspeed crew is going to do is baseline the car on the dyno, and if nothing sticks out like a sore thumb, proceed to do a compression check, and check the health of the engine’s timing chains and guides, and oil pump gears.

Some would accuse this author of having as dirty an engine compartment as Brenspeed’s project car, but we don’t remember any of them looking this downtrodden. Even though the engine compartment looked neglected, a full service history was available with the car, which is why Brenspeed chose this car in the first place.

“As long as the car passes the inspection, we plan to move forward with a wicked build list that will address almost every aspect of performance from induction to exhaust, suspension and rearend, cooling, and a few other go fast goodies that you often find on a street/strip coyote Mustang,” Brent reports. “Once complete the newly transformed coyote will be taken to the track to see just how it performs.”
