The stock 1.5-liter four-cylinder was extracted and rebuilt using Arias pistons and a Bisimoto valvetrain, but the star of the show is that massive billet Turbonetics turbo. It shoves ample amounts of air through a 70-millimeter custom throttle body at a rate that has to rival most jet engines. The whole kit and caboodle is good for a staggering 533 horsepower, which helps explain why a car that started life with a 0-60 mph time of 10 seconds now requires a parachute to reduce its inertia.
