Although “Jay Leno’s Garage” focuses primarily on the comedian’s personal collection, he does invite other enthusiasts to stop by with their unique cars. On this episode, Leno invited Matt Brown and his hot-rodded 1964 Honda S600 roadster to his garage.
After finding the engine-less S600 offered for sale on an internet forum, Brown decided to drop in a sport bike engine; specifically the 1.0-liter inline-four-cylinder engine from a 2007 Honda CBR1000RR that makes roughly 160 hp and revs to 12,000 rpm. The bike’s stock transmission backs the engine, while the car’s chain-drive rear end has been replaced by a two-piece BMW driveshaft that sends power to a BMW rear differential with Mazda Miata half-shafts and outboard brakes. A nitrous kit was added for a bit more fun, because, as Brown puts it, "Why not?"
Although Brown initially wanted to fix up the exterior, he decided to leave it as is for a rat rod look. With Brown doing most of the fabrication work, he estimates that the total build cost around $5,000. After checking out all the mods, Leno takes the Honda S600 out for a spin.
