Grind Hard Plumbing Co released several updates on their 1962 Triumph Spitfire project since our last article. In the previous update the team installed a 998 cc inline-four and CVT transmission from a 2003 Yamaha RX-1 snowmobile into the Spitfire. They are hoping the engine will output at least 200 hp thanks to a MPI Stage 1 supercharger kit. In the videos below the team works on the engine mounts, fuel lines, wiring, custom CVT drivetrain, and supercharger. Then it’s time to drive the unique project.
