Poway High School: Wild LS-Powered Exomotive Exocet
When Joseph Cousin, an auto shop teacher at Poway High School, set out to inspire his students, he didn't just crack open another textbook. He ripped out the pages with help from a 539-horsepower, 1,920-pound monster—and then unleashed it on the road course at LS Fest West.
LS2... Meet My Little Friend
The project started with an Exomotive Exocet kit, a purpose-built chassis designed to repurpose the drivetrain of a first-gen Miata. Typically, the idea is simple: strip down a donor Miata, bolt the rolling chassis to the lightweight Exocet frame, and go racing. But Cousin and his students had bigger dreams.
"We kept the Miata's steering knuckles, steering column, and rear subframe—everything else, we upgraded," Cousin says. A bored and stroked LS2 block, topped with ported LS3 heads and breathing through a Holley Hi-Ram intake are at the heart of the build. Under the "hood" are Holley accessory mounts and a low-profile oil pan. A Holley Terminator X ECU manages it all, while an 8.8-inch independent rear from a Cobra and a T-56 six-speed transmission pulled from a GTO put the power to the ground. With 539.5-wheel horsepower and less than 2,000 lbs, the power-to-weight ratio is absolutely bonkers.
Cousin was offered to try out Vitour tires. Even on smaller 245-width rubber compared to the original 275s, the grip immediately improved. "Cold tires, hot tires—it didn't matter," Cousin says. "The Maturos just stuck."
Built by Students, Powered by Passion
Over the course of 10 months, 35 students at Poway High School got their hands dirty. Some helped tear down and rebuild the engine after a spun bearing. Others installed suspension, mounted seats, or learned wiring fundamentals. "When you're teaching auto shop, a lot of the time it's oil changes and tire rotations," Cousin explains. "Getting to show them real performance builds—that's what really hooks them."
With just nine students able to attend LS Fest West in person, Cousin hopes this project will open the door to even bigger opportunities for future classes.
Track Day Firsts and Future Plans
LS Fest West marked the very first time Cousin—and the car—hit a full course. "I'm nervous, I'm shaking, but it's an absolute blast," he says, grinning after a session. "Each lap, the times are coming down. That's all I can ask for."
The car, already carrying a California-issued VIN, is on its way to becoming fully street-legal. "The only event that we have is what Holley throws, really, to be honest. Getting them out here to be able to see the performance side really gets the kids interested."
This green beast is not just a track weapon—it's a rolling lesson in creativity, craftsmanship, and what happens when you give the next generation the tools to dream big.
